Each image format has its own strengths depending on how you use it. JPG is great for photos and has the widest compatibility, PNG excels at logos and icons that need transparent backgrounds and crisp edges, and WEBP packs the same quality into a smaller file, which helps web performance. This tool freely converts between all three — JPG, PNG and WEBP — so you can switch to whatever format a platform requires or a task calls for.
When you convert a PNG with a transparent background to JPG, JPG does not support transparency, so the transparent areas are automatically filled with a white background to keep the colors from breaking. When converting to a lossy format (JPG or WEBP), a quality slider lets you balance file size against image quality; when converting to lossless PNG, there is no quality setting and the quality is preserved as-is. Every conversion runs on the browser Canvas and your image is never uploaded to a server, so you can change formats even for sensitive material with peace of mind.
It helps to remember that converting a format cannot create new quality. Turning a photo that has already been compressed as JPG into PNG will not bring back the lost detail. It does, however, make the file easy to store without further loss or to use in transparent compositing afterwards. Conversely, if your goal is to make a photo lighter, it is more efficient to convert to JPG or WEBP while adjusting the quality.
How to Use

- 2
Choose the target format
Pick JPG, PNG or WEBP. Use WEBP/JPG for photos, and PNG when you need transparency.
- 3
Adjust quality (optional)
When converting to JPG or WEBP, the quality slider lets you balance file size and image quality.
- 4
Convert and download
Click Convert to see a preview and the resulting file size, then save it with the download button.
When It's Useful
Switch to WEBP for web performance
Convert photos to WEBP to fit the same quality into a smaller file and speed up your site loading.
When you need a transparent PNG
Convert JPG photos to PNG or WEBP so they are ready for later logo compositing or transparent-background work.
Fix compatibility issues
When an older program or print shop cannot read WEBP, convert to the most widely supported JPG or PNG.
Flatten a transparent PNG to JPG
Fill the transparent areas with a white background so the image drops cleanly into upload forms or documents that assume a white background.
Tips
- If site speed matters, convert photos to WEBP to reduce file size.
- If you must keep a transparent background, convert to PNG or WEBP. Converting to JPG turns transparent areas white.
- When converting to JPG or WEBP, use the quality slider to balance size and quality. PNG is lossless, so it has no quality setting.
- When submitting to a print shop or an older system, the widely supported JPG is the safe choice.
- Images with crisp color edges, like logos and icons, look sharpest as PNG.
- For a photo you have already finished editing, WEBP offers better quality-per-size than PNG, which is handy for storage and sharing.
FAQ
Which formats can I convert between?
JPG, PNG and WEBP convert freely among one another. When you add an image, the default target is set automatically to avoid converting to the same format.
What happens when I convert a transparent PNG to JPG?
JPG does not support transparency, so the transparent areas are filled with a white background. To keep transparency, convert to PNG or WEBP instead.
Does WEBP open everywhere?
Modern browsers and most platforms support WEBP. Some older programs may not open it, though, so if compatibility matters, use JPG or PNG.
Can I adjust the quality during conversion?
A quality slider appears only when converting to JPG or WEBP. PNG is a lossless format, so the quality setting does not apply.
Is my image uploaded to a server?
No. Every conversion is processed in your browser and your image is never sent anywhere.
Does converting reduce quality?
Converting to PNG is lossless, so quality is preserved. JPG and WEBP are lossy formats, so there may be a slight loss depending on the quality setting.
Does converting a JPG to PNG improve quality?
No. Information that has already been lost will not come back. That said, PNG is better for storing without further loss or for transparent compositing afterwards.
My file got bigger after converting.
Converting a photo to PNG makes it lossless, so it is normal for the file to be larger than JPG or WEBP. To reduce size, convert to WEBP or JPG, or use the 'Compress Image' tool.
