Frequently asked questions about Watermark PDF
Short, accurate answers to the questions readers ask most often about using Watermark PDF for PDFs. Browser-based, free, no signup, runs entirely on your device.
If you've ended up here, you have a PDF and a specific job: common questions. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.

Why common questions needs different settings
A PDF for common questions optimises for things the original PDF doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

What to verify before sending
Quick check-list once Watermark PDF finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
Can I undo the compression later?
No — compression is one-way. Always keep the original PDF archived somewhere, and treat the compressed version as a send-only copy.
Is Watermark PDF safe for sensitive PDFs like a resume or visa documents?
Yes — every step happens locally in your browser. The PDF never leaves your device because there is no server in the loop.
What if the recipient asks for the original?
Keep the original. Watermark PDF produces a copy; the source file you dragged in is never modified.
Should I rename the result?
Often yes. Recruiters and portals often pre-filter by filename patterns; a clean, predictable name (e.g. "FirstName_LastName_Resume.pdf") is worth the 10 seconds.
