The Essential Guide to PNG to JPEG Conversion
Converting PNG files into JPEGs is a common image optimization task with many use cases. In this comprehensive guide, we’ll cover everything you need to know about PNG to JPEG conversion.
As leading providers of online marketing tools, Optimized24 offers the best PNG to JPEG converter available today. With both free and paid options, our image converter allows effortless batch conversion to reduce PNG file sizes while maintaining quality.
Overview of Key Image Formats
Before diving into PNG to JPEG conversion, let’s briefly overview these key image file formats.
PNG (Portable Network Graphics)
PNG is a raster or bitmap image format that utilizes lossless data compression. Key features include:
- Lossless compression – All image data is preserved
- Supports transparency – Pixels can be fully transparent
- Useful for diagrams, logos, icons and text
- Larger file sizes than JPEG
JPEG/JPG (Joint Photographic Experts Group)
JPEG is a lossy compressed file format designed for photographic images. Key features include:
- Lossy compression – Data is discarded to reduce file size
- No transparency support
- Better compression for photographic images
- Wide compatibility across web and devices
- Smaller file sizes than PNG
Lossless vs Lossy Compression
- Lossless retains all original data. PNG uses lossless compression.
- Lossy discards data to achieve higher compression. JPEG uses lossy compression.
When to Use Each Format
- PNG is better for logos, text, diagrams with flat colors and shapes. The lossless compression and transparency support are key advantages.
- JPEG is more suitable for photographic images like photos. The lossy compression provides much smaller files sizes, ideal for web use.
Now that we’ve compared the PNG and JPEG formats, let’s look at common reasons for converting between them.
Why Convert PNGs to JPEGs?
There are many scenarios where converting from PNG to JPEG can be advantageous, despite the loss of data.
1. Reduce File Sizes for Web Use
PNG files can be 2x to 5x larger than an equivalent JPEG. Converting to JPEG can significantly reduce image file sizes for web use. This helps pages load faster.
2. Improve Compatibility
JPEG is supported across more web browsers and devices than PNG. Converting PNGs to JPEGs improves compatibility issues.
3. Prepare Images for Print
PNGs with transparency often need to be flattened and converted to JPEG for commercial printing. JPEGs also offer better CMYK color management for print.
4. Optimize Images for Social Media
Leading social platforms like Facebook and Twitter recommend JPEG for image uploads over PNG due to better compression.
5. Edit Images in Apps Limited to JPEG
Some mobile apps for editing images may only support the JPEG format. Converting PNGs allows them to be opened.
For these reasons, most digital images go through PNG to JPEG conversion during their lifecycle. The key is determining optimal settings to balance quality and file size.
Methods for Converting PNG to JPEG
There are many options available to convert PNG images into JPEGs, both free and paid. Let’s compare the leading methods.
1. Online Converters
Using a free online PNG to JPEG converter is the fastest and easiest option. Simply upload your PNG files or enter an image URL to convert instantly.
Optimized24’s image converter is an industry leading online tool that allows batch conversion too. There are also advanced customization options available in the paid version.
2. Desktop Applications
Installing a desktop image editing app like Photoshop or GIMP allows PNG to JPEG conversion. This works well for occasional conversions, but lacks batch processing features.
3. Command Line Tools
For developers, ImageMagick provides command line interface (CLI) tools for scripting and automating PNG to JPEG conversion. The learning curve is higher but provides more control.
4. Programming Libraries
Conversion can be directly built into apps using libraries like Python’s PIL or Pillow. This allows PNG to JPEG conversion features within a custom solution.
For most users, an online converter or desktop app will be the most accessible options. But developers have great flexibility using command line or coding solutions too.
Optimizing Conversion Settings
When converting PNG to JPEG, there are some key settings to consider for controlling quality and file size.
JPEG Quality Level
This sets the amount of compression applied, from 1 to 100. Lower values give smaller files but lower quality. Values between 60-85 are common for optimal web use.
JPG does not support transparency like PNG. The background must be flattened to a chosen color, usually white or grey.
Resampling the image to a lower resolution before conversion can further reduce JPEG file size. But quality loss may be unacceptable for print use.
Most converters will discard PNG metadata like color profiles by default. Some allow metadata transfer to the JPEG to preserve it.
Testing different settings will determine the optimal balance between quality and filesize for your images. Batch conversion tools allow these parameters to be reused.
Leading Use Cases and Applications
Now let’s explore some of the most common applications and use cases for converting PNG images into the JPEG format.
Web Design and Publishing
Using PNG to JPEG conversion to optimize images for web use is certainly the most common scenario. The reduced file sizes accelerate page loading speeds while still retaining quality. JPEG images also avoid the browser compatibility issues of PNGs with transparency.
Social Media Marketing
Leading social platforms all recommend JPEG images over PNGs. Facebook, Twitter, Instagram, LinkedIn and others all compress images during uploads, so starting with JPEG avoids double compression artifacts. Marketing teams routinely convert PNG graphics and logos to JPEG before uploading to social media.
Photo Editing and Retouching
Many graphic designers work with stock PNG images that ultimately need to be delivered in JPEG format. Rather than export JPEGs directly from Photoshop or other editors, converting via a dedicated tool allows you to preview the impact of different compression settings on quality.
While PNG is a better format choice over JPEG for print graphics, some transparent PNGs will still need to be flattened and converted to JPEG prior to commercial printing. Printing presses and software utilize different color profiles that are better supported by the JPEG format.
Mobile Apps and Games
Due to slower processors and limited memory on smartphones, mobile apps often only support JPEG images. Game developers need to convert any transparent PNG textures into JPEGs before imported into app projects. Online converters provide an easy solution.
Amateur photographers using entry level cameras or smartphones capture images in JPEG format. But raw images from DSLRs are often processed into PNGs for editing flexibility. Converting back to JPEG maintains compatibility with devices and online platforms.
As you can see, PNG to JPEG conversion plays an integral role in countless modern digital imaging workflows. The optimal tool depends on your specific use case and requirements.
The Pros and Cons of JPEG Images
Now that we’ve covered the key reasons and methods for conversion, let’s examine the advantages and disadvantages of using JPEGs over PNGs in more depth.
The Pros of JPEG Images
- Smaller file sizes – Compression ratios of 10:1 or more versus PNG
- Web compatibility – Supported by all major browsers and devices
- Printability – CMYK color management better suited for commercial printing purposes
- Memory efficiency – Smaller file sizes use less RAM when editing images
- Sharpness – Lossy compression reduces file noise compared to lossless PNG
The Cons of JPEG Images
- Lossy compression – Image quality degradation from discarded data
- No transparency – Flattening PNGs can introduce artifacts
- Generational loss – Repeated saves/edits decrease quality over time
- Color banding – Limited color palette can create banding artifacts
- Less pixelation resistance – Upscaling JPEGs creates more pixelation than PNG
The pros of smaller file sizes and broad compatibility need to be weighed against the lossy compression trade-offs. Testing different JPEG quality settings minimizes the downsides.
The Pros and Cons of PNG Images
In contrast, PNG offers some unique advantages but has compatibility and performance challenges.
The Pros of PNG Images
- Lossless compression – Retains all original image data
- Transparency support – Pixels can have variable transparency
- Print graphics – Sharper text and line art details

Resolution and Re-Sizing Considerations
When converting PNGs to smaller JPEG versions, changes to the image resolution and dimensions may also be required depending on the target use case.
Here are some key re-sizing considerations:
Web and Mobile Requirements
Understanding platform specifications allows matching target device displays:
- Desktop web: 72-96 PPI
- Mobile web: 192+ PPI
- iOS: 72, 167, 326 PPI
- Android: 96, 192, 480 PPI
Printing requires much higher resolution images:
- Standard print: 300 PPI
- High resolution print: 600+ PPI
Increasing image dimensions will decrease resolution. This can introduce unwanted pixelation artifacts.
Reducing dimensions will increase resolution. But may discard important details from the image.
Loss of Transparency
PNG re-sizing that adds canvas area fills with white or other color backgrounds.
Smart Re-Sizing Algorithms
Advanced tools like Optimized24 utilize intelligent resampling methods like Lanczos to minimize quality loss when re-sizing images.
Understanding resolution requirements of different mediums ensures the converted JPEGs have suitable print or digital dimensions. Intelligent re-sampling also avoids degradation during any required up or down-scaling.
Leveraging Image Metadata
PNG and JPEG images have different approaches to encoding supplemental metadata like color profiles, creation dates, and other embedded data:
- Utilizes tEXt, iTXt and zTXt chunks to store metadata
- Metadata remains intact when converting PNG to PNG
- Uses Exif, IPTC and XMP standards for metadata
- Some data may not transfer when converting PNG to JPEG
To retain maximum metadata when converting PNG to JPEG:
- Opt for “Copy metadata” option if converting within an image editor
- Use converter tools that actively transfer metadata
If full metadata transfer is not possible, determine most crucial data to retain:
- Color profiles
If needed, some metadata can be re-added after conversion:
- EXIF data with CLI tools like exiftool
- Copyright via image watermarking
- Location data by geotagging
Conscious metadata management ensures valuable supplemental data like color space profiles can still be leveraged after PNG to JPEG conversion.
Reviewing File Size Optimization
A core benefit of converting transparent PNGs into JPEG format is the potential for huge reductions in file size. But what savings can you expect?
Here are some typical PNG to JPEG compression ratios:
- PNG: 100 KB
- JPEG: 20 KB
- 4-5x smaller
Graphics and Logos
- PNG: 50 KB
- JPEG: 15 KB
- 3-4x smaller
High Complexity Images
- PNG: 150 KB
- JPEG: 100 KB
- 1.5x smaller
Some tools offer lossless JPEG conversion of PNGs by archiving the discarded image data into the JPEG’s metadata. File sizes are only marginally smaller – expect less than 20% reduction.
The amount of optimization depends on image content as well as JPEG quality level selected. For web use, 60-85% quality levels are recommended. Lossless conversion is better suited for maximizing quality over optimization.
Remember that excessive JPEG compression introduces visual artifacts like blocky patches of color and smearing called “JPEG artifacts”. Regular testing during conversion avoids going too small.
Integrating PNG to JPEG Conversion Into Workflows
Now we’ll explore practical ways that PNG to JPEG conversion can be integrated into content production and web publishing workflows.
Export icons, logos and static graphics as PNG during design. Then batch convert to JPEG before delivering final assets to clients and partners.
Optimize any transparent PNGs within compiled source assets like spritesheets and bundles by converting them into web-ready JPEGs.
Maintain a PNG master archive but batch convert a JPEG copy of each image to embed into website posts and pages.

Troubleshooting Guide and Tips
Despite the wide use of JPEG format, you may occasionally encounter issues when converting PNG images. Here are some troubleshooting tips:
This “macroblocking” happens when JPEG quality is set too low. Try increasing quality settings.
If images appear soft after conversion, reduce any downscaling or disable smoothing filters.
Color banding is caused by too few colors. Try higher JPEG quality or adjust levels prior to conversion.
Halos around image edges happen when flattening transparent areas. Use cleaner isolation before converting.
Incorrect colors, contrasts or gamma after conversion are often due to lost metadata. Ensure color profile transfer if possible.
Large or high resolution PNGs will slow down conversion. Try sizing before converting and/or use accelerated services.
Following best practices for properly resizing, setting appropriate quality levels, and preserving metadata will help avoid most conversion issues.
Platform-Specific Concerns and Limitations
Depending on your operating system and software environment, there may be PNG compatibility considerations to keep in mind:

Individual Image Extraction
Specialized tools can identify and extract all embedded PNG, JPEG and other image formats within a PDF automatically. This avoids manual capture.
Text Layer Removal
Eliminating text layers and flattening any remaining transparent layers during conversion streamlines repurposing of extracted diagrams and figures.
Multiple Resolution Exports
When extracting images from PDFs, exporting both web resolution ~96 PPI and higher print resolution ~300 PPI copies can be beneficial for versatile reuse.
Automated batch conversion of PDF pages or graphics into JPEG accelerates digitizing large documents or publications for web access.
Native PDF Optimization
Beyond conversion, optimizing the original PDF itself by removing redundant objects, compressing images, and other tactics can significantly reduce source file size.
Like PNG, conversion to JPEG is often the optimal approach for publishing PDF graphics online. But retaining an archive of the PDF allows high resolution printing too.
Other Leading Image Conversions
Beyond PNG and PDF, there are many other common image conversion scenarios:
TIFF to JPEG
Archival TIFFs can often be 10x larger than JPEGs. Converting offers huge savings for web use while still retaining high print quality.
RAW to JPEG
Camera RAW files allow extensive editing options. But JPEG remains the standard delivery format to clients.
PSD to JPEG
Exporting JPEG copies from PSD design files reduces sizes drastically compared to layer-retained PSDs.
GIF to JPEG
Animated GIFs are extremely limited in colors and quality. JPEGs are preferable for nearly all photographic images.
BMP to JPEG
The BMP format offers high quality but very large files, even larger than PNGs. JPEG conversion delivers extensive optimization.
WEBP to JPEG
Despite benefits like smaller files, WEBP remains poorly adopted. JPEG conversion enables broader device support.
AVIF to JPEG
Similarly, AVIF has yet to achieve meaningful adoption outside of Chrome and a few tech early adopters. JPEG remains the pragmatic choice.
HEIC to JPEG
iOS uses the HEIC format for space savings, but compatibility issues require users to manually convert photos to JPEG.
Carefully converting from specialized formats into industry standard JPEG enables reaching the broadest audience online and across devices.
