Will converting JPG to PNG improve image quality?

No — and this is the most common misunderstanding. PNG is lossless, so it preserves the JPG exactly as it currently looks, including any compression artifacts. It cannot recover detail or remove blockiness that JPG already discarded. What PNG does is prevent any further loss from future edits and saves.

Why would I convert JPG to PNG then?

Mainly two reasons: to stop quality degradation during repeated editing (every JPG re-save loses a little more), and to gain transparency support so you can cut out a background or composite the image.

Why is the PNG larger than the JPG?

PNG stores image data losslessly while JPG compresses aggressively. For a photographic image, the PNG can be several times larger. That extra size is the cost of lossless storage.

Does the PNG get a transparent background automatically?

No. Converting does not remove the existing background — the image looks the same. PNG simply gives you a format that can hold transparency once you erase areas in an editor.

Are my photos uploaded to a server?

No. Everything runs in your browser via WebAssembly and your device's image encoder. Files never leave your machine.

Can I batch convert JPGs to PNG?

Yes — up to 20 files at once, downloadable as a single ZIP.

Is there any quality setting?

PNG is lossless, so there is no quality slider — it always preserves the image exactly.

What is the maximum file size?

100MB per file, ample for high-resolution photos.
