Frequently asked questions
Can I remove a watermark later?
Keep your original file. The watermark is drawn onto the saved copy, so use the original if you need a clean version.
Can the watermark be diagonal?
Yes. Choose the diagonal layout for slanted text across the page, or horizontal for straight text.
Can I use Arabic text?
Not yet. Use English letters, numbers and common symbols.
Is my PDF uploaded?
No. The tool runs in your browser, so the file is processed on your own device and is not uploaded to our servers.
