What happens when you convert JPG to PNG
JPG is the universal photo format: lossy compression, no transparency, and support in essentially every piece of software ever written. PNG is a lossless format with full alpha transparency — ideal for screenshots, logos, and artwork with sharp edges, at the cost of larger files for photos.
- Expect the file to grow: PNG is lossless, so it faithfully stores JPG's compression artefacts too.
- PNG is lossless, so the output matches the decoded source pixel for pixel.
- EXIF metadata, including GPS coordinates, is dropped. Orientation is applied first, so the image stays the right way up.
- The file is converted in memory and streamed straight back — nothing is written to disk or saved to an account.
Frequently asked questions
Is converting JPG to PNG free?+
Yes — free, no watermark, and no account required. Signing in raises the per-file size limit and is the only reason you would need one.
Do you store the images I convert?+
No. Conversion happens in memory during the request and the result is streamed back to your browser. The file never touches our disks or database, and there is nothing to delete afterwards.
Will I lose quality converting to PNG?+
PNG encoding itself is lossless, so nothing is lost in this step. Quality already lost when the source was saved as JPG cannot be recovered, though — lossless output preserves the artefacts rather than removing them.
Is there a limit on file size?+
Guests get a smaller per-file limit than signed-in accounts. If a file is rejected as too large, signing in is usually enough to get it through.
Can I convert PNG back to JPG?+
Yes — the PNG to JPG converter handles the reverse direction.
