Watermark PDF

Mark every page.

One or many · 50 MB each

Add a diagonal text watermark such as CONFIDENTIAL or DRAFT across every page before sharing. Stamp once, then protect or compress without re-uploading.

When to watermark

Mark drafts, NDAs in review, internal financials, and anything that should not be mistaken for a final public copy.

Watermark is not encryption

A stamp discourages casual misuse and signals intent. Pair with Protect if the file must require a password to open.

Studio chaining

Typical path: strip metadata → watermark → compress → protect. One upload through the whole checklist.

Common questions

Can I customize the watermark look?
You set the text. Filemynt applies a consistent diagonal stamp designed to stay visible without fully blocking content. Advanced style controls may expand later.
Does watermarking work on every page?
Yes. The stamp is applied across the document so no page is left unmarked.
Can I watermark a batch?
Yes. Studio can watermark multiple files and return a ZIP when you need the same mark across a set.
Is my watermarked file private?
Yes. Uploads and the stamped result are handled over an encrypted connection and deleted on a short schedule (typically within about one to two hours). Filemynt keeps no copies and never uses your files for advertising or training.
