JPG to PNG Converter

No — and nothing can. JPG compression already discarded detail when the file was created, and PNG simply preserves whatever is left perfectly. The benefit is that further edits and saves will not degrade it any further.

That is expected. JPG is lossy and PNG is lossless, so a photo typically becomes three to five times bigger as a PNG. Convert only when you actually need PNG; otherwise keep the JPG.

PNG supports transparency but the conversion cannot invent it — a JPG has no transparent pixels, so the result is fully opaque. You will need an editor to remove a background.

There is no fixed limit. Because everything runs locally, the practical ceiling is your device’s memory — batches of 20–50 photos are comfortable on a typical laptop.

Yes, completely. There is no account to create, no trial that expires, no watermark on the output and no feature held back behind a paywall. The site is supported by unobtrusive advertising, not by charging you.

Yes. Because processing happens locally, there is no copy of your data on any server to leak, subpoena or lose. Nothing is logged and nothing is stored.

Yes. The interface is built mobile-first, with touch-friendly controls and layouts that adapt to small screens. Everything that works on a desktop works on a phone.

Any current version of Chrome, Edge, Firefox, Safari or Opera, on desktop and mobile. If something behaves oddly, updating your browser resolves it in almost every case.

There is no server-side limit because nothing is uploaded. Files up to about 50 MB are comfortable on a typical device; beyond that, processing speed depends on your machine's memory.

Yes. Whatever you produce here is yours — use it in client work, products, packaging or publications. There is no watermark, no licence to accept and no attribution required.

No. There is nothing to keep: your data is never transmitted, and it is cleared from memory as soon as you close or reload the page.
