Frequently asked questions
Are my images uploaded to a server?
No. Every image is processed locally in your browser using your own device. Nothing is ever sent anywhere, which is why it still works with your wifi switched off.
Which formats can I convert to?
You can convert to WebP, AVIF, JPG, PNG, GIF, BMP and ICO. WebP and AVIF give the smallest files for the web, while PNG stays lossless with transparency.
Is there a file size or batch limit?
There is no hard limit. You can drop many images at once and the only real constraint is your device memory.
