Are my images uploaded to a server?

No. Every conversion runs locally in your browser using the Canvas API, so your images never leave your device and we never see them.

Which formats can I convert between?

You can convert between PNG, JPG/JPEG and WebP, and use a GIF as input (its first frame is converted). WebP usually gives the smallest files at a given quality.

Is there a file size or quantity limit?

There are no artificial limits — convert as many images as you like. Very large files are limited only by your device’s available memory.

Will converting reduce my image quality?

PNG is lossless, so quality is preserved exactly. For JPEG and WebP you control quality with a slider, and the tool shows the resulting file size so you can find the right balance.

Does it work on a phone?

Yes. The converter is fully responsive and runs in any modern mobile or desktop browser — there is no app to install.
