FAQ

Are my files uploaded?

No. The conversion runs locally in your browser and the original file stays on your device.

Why convert JPG to PNG?

PNG is the default output for this tool and is useful when you need a lossless image or transparency. You can also start with PNG, WebP, HEIC or HEIF images and choose another available output format.

Can I convert files on a phone?

Yes, if the mobile browser supports the required local decoding APIs. Large files may need more memory.
