  3. Stamp it, then download.

When the browser is not enough

scanmydocz for Android

Live edge detection through the camera, text recognition that makes the PDF searchable, a signature you can place, and batch capture. All of it on the phone.

In closed testing. There is no public Play link yet, so there is no button here yet.

scanmydocz Pro

Pro is the paid tier in the Android app. It cannot be bought on the web yet, because checkout is not connected, and we would rather say that than show you a price you cannot pay.

Questions

Does a watermark protect the document?

No, and anyone telling you otherwise is selling something. Anything drawn onto a page can be taken off again by whoever can open the file. A watermark makes a leak traceable and stops an old draft being mistaken for the final version. It is not a reason it is safe to send something.

Will it cover the text?

Light is the default for that reason: it sits behind the reading without fighting it. Medium and heavy are there when being unmissable matters more.

Why is the size different on different pages?

It is sized to each page rather than fixed. The same setting that suits A4 would run off the edge of a receipt and vanish on a poster.

Is my file uploaded?

No. The stamping happens in this page.
