FAQ

Are my files uploaded anywhere?
No. This tool runs entirely in your browser. Your files and text are processed on your own device and are never uploaded to our servers.
Will text stay selectable?
In Lossless mode, yes — the document is rebuilt without changing content. Strong modes turn pages into optimised images, which shrinks scans dramatically but makes text unselectable.
