FAQ
Frequently asked questions
Is there a file size limit?
Images up to 50 MB are supported. Everything happens in your browser’s memory, so very large images depend on your device.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you type, paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
