How to Convert JPG to PNG

The output file name matches the original with the extension swapped to .png.
Why Convert JPG to PNG?
PNG uses lossless compression, meaning every save is exact — no artefacts, no quality decay. Once you have a PNG you can edit and re-save it hundreds of times without any degradation. PNG also supports a transparency layer (alpha channel), which makes it the go-to format for logos, icons and graphics that need to sit on coloured backgrounds. JPG is great for photos; PNG is better for anything that needs editing or transparency.

Frequently Asked Questions
Does JPG to PNG conversion improve image quality?
No. Converting JPG to PNG does not recover detail lost when the JPG was originally compressed. However, saving as PNG stops further quality loss — the image will not degrade on subsequent edits and re-saves.
Will the PNG file be larger than the JPG?
Yes, almost always. Because PNG is lossless, it stores more image data. Photographs typically result in PNG files 2–5× larger than the equivalent JPG. If file size is a concern, use our Image Compressor after converting.
Does PNG support transparent backgrounds?
Yes — PNG supports full alpha-channel transparency. However, since the source JPG has no transparency data, the converted PNG will have a solid background matching the original.
Is my image uploaded to a server?
No. This tool runs entirely in your browser using the HTML5 Canvas API. Your image is never sent anywhere — it stays on your device throughout the entire conversion process.
