Frequently asked questions

 

How many images can I resize at once?

Up to 50 images per batch. Everything is processed in your browser, so very large batches depend on your device memory.

Are my images uploaded?

No. Resizing happens locally with the HTML5 Canvas API and nothing is sent to a server.

Is it free and private?

Yes. It is free, needs no account, and your files never leave your device.
