File Watermarker stamps a reader's name and email onto their own copy of your book, so a leaked copy can be traced back to them.

Make a copy for one reader

  1. Open File Watermarker from the sidebar.
  2. Under 1. File Configuration, drop a PDF or EPUB onto the box, click Browse…, or click Choose from Storage to use a file you've already uploaded.
  3. Under 2. Watermark Settings, check the Book. It's usually filled in from the file you chose.
  4. Enter the Reviewer Name and Reviewer Email.
  5. Check the Reviewer Text. This is the exact text stamped onto the file. It fills in from the name and email, and you can edit it.
  6. Look at the Preview to see how the stamp will look.
  7. Click Apply Watermark.

Get the copy to your reader

When it's done, 3. Send File lists the new copy.

  • Click Save… to download it to your computer.
  • Click Email to send the reader a download link from your connected email account.

Without a connected email account you can still make and download copies, but you can't email them from here. Connect Gmail or a custom SMTP account in Settings under Email.

Good to know

  • Files you upload here are saved to your active storage, so you can choose them again later.
  • Each copy can be downloaded for 30 days, then it's deleted.
  • To make copies for a whole review team at once, turn on Enable batch mode.
