JPG to PNG Converter
PNG is the format to reach for when an image will be edited, layered, or re-saved several times. Unlike JPG, PNG never re-compresses your pixels, so nothing degrades between saves — the trade-off is a noticeably larger file.

How to convert JPG to PNG
- 1Drop the JPG onto the converter.
- 2Select PNG as the output format.
- 3Convert and download — PNG has no quality setting because it is lossless.
Things worth knowing
- Converting to PNG cannot recover detail that JPG compression already removed; it only prevents further loss.
- Expect the PNG to be considerably larger, often 2–5× the JPG, especially for photographs.
- PNG supports transparency, but a converted JPG will be fully opaque — you still need an editor to cut out a background.
JPG to PNG — frequently asked questions
Does JPG to PNG improve image quality?
No. The compression artefacts baked into the JPG stay exactly where they are. What PNG gives you is a guarantee that no further quality is lost during future saves.
Why is my PNG so much bigger?
PNG stores every pixel exactly, while JPG discards detail the eye barely notices. Photographs, which have few repeating pixels, compress poorly in PNG — that size increase is expected, not an error.
Are my files uploaded to a server?
No. AllConverter runs the whole conversion inside your browser tab using WebAssembly and the Canvas API. Your file never travels over the network, which you can confirm by watching your browser's Network tab while you convert.
