JPG to PNG Converter

How it works

Each JPG is decoded into a canvas and re-encoded losslessly as a PNG. The original JPG compression artifacts remain (PNG cannot undo lossy compression), but no further quality is lost.

Frequently asked

Does converting JPG to PNG improve quality?

No. PNG is lossless, but it cannot restore detail that JPG compression already discarded. The PNG will look identical to the JPG; only the file size and format change.

Why would I convert JPG to PNG?

PNG is required by some tools and platforms (some chat apps, print services, transparent-background workflows). PNG is also better for further editing because it does not re-compress on each save.

Will the PNG be bigger than the JPG?

Usually yes — PNG is lossless so photographic content is 3–10× larger than the equivalent JPG. Screenshots and graphics may stay similar or shrink.

Is the conversion safe?

Files never leave your device. The entire conversion runs in your browser using the standard Canvas API.
