Frequently Asked Questions

Are my images uploaded anywhere?

No. Every image is converted directly in your browser using the Canvas API. Your files never leave your device — nothing is uploaded to any server.

Which formats can I convert to?

You can export to JPG, WebP and PNG. Input can be PNG, JPG, WebP, GIF, BMP and most images your browser can open.

Why convert PNG to JPG?

PNG is lossless and often very large for photos. Converting to JPG (or WebP) with a sensible quality setting can shrink the file size dramatically while looking virtually identical.

Is there a file size or count limit?

There are no artificial limits — only your device’s memory. You can process up to 100 images per batch.
