JPG to PNG converter

Drop a JPG here and you get a PNG back, immediately.

A JPG throws away detail to keep the file small, and it throws a little more away every time it is re-saved. A PNG keeps every pixel exactly as it was and can hold transparent areas, which is why logos, screenshots and diagrams belong in PNG. Converting a JPG to PNG will not put back the detail the JPG already discarded — but it stops any further loss, which matters if the image is about to be edited and re-saved several times.

Expect the PNG to be larger than the JPG it came from. That is the trade: PNG stores everything, JPG stores an approximation.

If transparency is your reason for wanting a PNG, converting will not give you any. A JPG has no transparent areas to recover, so the result is a fully opaque PNG; you need the original artwork for that.

Accepts: image/png, image/jpeg, image/webp, image/gif, image/bmp, image/avif

Questions

Will converting to PNG improve the quality?
No. Detail lost when the JPG was first made cannot be recovered. What you gain is that no further detail is lost from this point on.
Is there a file size limit?
Only your device's memory. Nothing is sent anywhere, so there is no upload limit to hit.
