Frequently asked questions
Will the PNG be bigger?
Usually yes. PNG stores pixels losslessly, while JPG compresses photographs aggressively. Expect PNG files several times larger for photographic content.
Does quality change anything?
Not here. PNG encoding is lossless, so the quality slider has no effect for this conversion.
Are EXIF photos supported?
Yes. The pixels are decoded and re-encoded as PNG; metadata is not carried into the PNG container.
Is anything uploaded?
No. Decoding and encoding happen in your browser tab.
Privacy
Images are decoded and re-encoded locally. No bytes leave your device.
No account is required and no file is ever uploaded. See the privacy policy for details about analytics and the limited data this site stores.
Known limitations
- PNG output is larger than JPG for photographs.
- Camera metadata is not carried into the PNG container.
- Extremely large images are limited by browser canvas dimensions.
