JPG to PNG Image
Convert a JPG into a lossless PNG.
JPG to PNG is a free online tool that convert a JPG into a lossless PNG. It accepts JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. It produces pNG, with transparency preserved.. It runs entirely in your web browser using Canvas 2D, so files are processed on your own device and never uploaded to a server. There is no sign-up, no file size limit imposed by the site, no watermark and no paid tier.

About JPG to PNG
Converting JPEG to PNG stops further quality loss but cannot undo what has already happened — the compression artifacts baked into the JPEG are copied faithfully into the PNG. It is worth doing before you start editing, so subsequent saves stay lossless, and pointless as a way to "improve" an image.
How to use it
- Choose an image, or drag one onto the drop zone.
- The defaults suit most images.
- Check the preview, then download. Output is PNG, so transparency survives. Your original file is never modified.

Questions
Will this make my photo look better?
No. PNG is lossless, so it preserves exactly what is in the JPEG, artifacts and all. It will however be several times larger, because PNG is poor at compressing photographic detail.
When is JPG to PNG worth it?
When you are about to edit and re-save repeatedly, when you need transparency added afterwards, or when a system specifically requires PNG. Not for archiving photos.
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
