What does the JPG to PNG converter do?

JPG is already lossy-compressed, so converting to PNG does not magically restore detail — it just stores the existing pixels without further loss. PNG is a good choice when you plan to edit the image further and want each save to preserve quality.

Will my PNG have a transparent background?

JPG files have no alpha channel, so the result will have a solid background. To get transparency in PNG, use the Remove Background tool on the PNG output.

Is the JPG to PNG conversion reversible?

You can convert the PNG back to JPG on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.

Will the PNG be larger than the JPG?

Yes — lossless containers store every byte. Expect the PNG to be 3-8x the size of the JPG. The benefit is no further quality loss on editing or re-encoding.

Is there a file-size limit when converting JPG to PNG?

Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.

Can I batch-convert several JPG files to PNG at once?

Yes. Drop or pick multiple JPG files in one upload — the converter processes them in parallel and returns a ZIP of the PNG results. There is no need to repeat the upload step per file.

What happens to my JPG files after the conversion?

Uploaded files and PNG outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.

Where can I open a PNG file?

PNG opens natively in every modern browser, every image viewer, and every photo-editing app. No additional software is needed.

Do I need to install software to convert JPG to PNG?

No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.

Do I need an account to convert JPG to PNG?

No. JPG to PNG conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.

Is there an API for JPG to PNG conversion?

Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. JPG to PNG is one of the supported pairs.

What if my JPG fails to convert to PNG?

Failures are usually caused by corrupted source files or unsupported JPG variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
