Does the conversion lose quality?

No. PNG is lossless, so every pixel from the decoded source is kept exactly. The file may be larger than the original if the source was a compressed photo.

What happens to transparency?

PNG supports transparency, so transparent areas in the source are preserved.

Can I convert many files at once?

Yes, add up to 100 files and they are converted one after another in your browser. The results can be downloaded together as a ZIP.

Are my files uploaded to a server?

No. This tool runs entirely inside your browser using JavaScript. Your files are read from your device, processed in memory, and the result is handed straight back to you as a download. Nothing is transmitted, stored or logged, and the page keeps working if you go offline after it has loaded.

Questions

Frequently asked questions

JPG is the universal photo format: small files, supported by every device and app, but no transparency and some loss of detail at low quality settings. PNG is lossless and supports transparency, which makes it ideal for screenshots, logos and graphics, at the cost of larger files for photos.
