Frequently asked questions

Will the text still be selectable?

Each page is rendered to a grayscale image, so the result is image-based and text is no longer selectable. Keep your original if you need the text layer.

Is my file uploaded?

No. The conversion is done on your device with an in-browser PDF engine; nothing is sent to a server.
