FAQ
JPG to PNG questions, answered
Why convert JPG to PNG?
Common reasons: a design tool insists on PNG, you want an alpha-capable container for editing, or you need a lossless re-save (further JPG edits keep degrading; PNG does not).
Will the PNG be bigger than the original JPG?
Usually yes — sometimes 3–8× bigger. JPG is lossy and very efficient on photographs; PNG is lossless. Converting JPG → PNG doesn't restore lost detail (the JPG already discarded it), but the file size grows because PNG keeps every pixel verbatim.
Is anything sent to a server?
No. The conversion runs entirely in your browser using the Canvas API. You can verify in DevTools → Network — nothing carrying your image leaves your device.
How many files can I convert at once?
No hard cap. The tool processes them sequentially to keep memory under control. We have tested with 50 files at 4000×3000 each without issue on a normal laptop.
Can I use these PNGs commercially?
Yes. The tool runs entirely on your device — we never touch the files, so usage rights stay yours.
