FAQ
Is this JPG to PNG converter free, with no upload?
Yes. The image is decoded and re-encoded in your browser using a Canvas + Wasm pipeline — it never uploads. No signup, no watermark.
Will converting JPG to PNG lose quality?
PNG can store the image losslessly (or near-losslessly), so converting from JPG preserves visual quality.
Does it preserve transparency?
Yes — the output format supports an alpha channel, so transparent areas in the source are preserved.
What is the maximum file size or resolution?
Up to 50 MB per image. Resolution caps depend on browser memory; modern browsers handle 12000 × 8000 px without issue.
