Frequently Asked Questions
Is it really free?
Yes, completely free and unlimited. The conversion happens in your browser using WebAssembly — there is no server to pay for.
Are my images uploaded?
No. Your images are processed entirely on your device and never leave it. You can verify this in DevTools → Network while converting.
Can I convert multiple images at once?
Yes — use Image Factory to build a batch pipeline: convert, compress, crop and resize many images in one flow, entirely on your device.
