Stamp DRAFT, CONFIDENTIAL, or custom text diagonally on each page. Optional page numbers — all in the browser.
PDF Watermark draws repeating text — DRAFT, CONFIDENTIAL, REVIEW COPY, or words you type — diagonally across every page of a PDF. Optional corner page numbers show “3 of 12” so reviewers can reference a stamped draft. The stamped file downloads with .watermarked in the name; your original PDF on disk is untouched.
Processing uses pdf-lib in the browser. No upload. That makes it reasonable for internal reports that still contain customer data while you want a visible label that the version is not final.
Legal and finance teams use stamps to slow mistaken reliance on a preview. Teachers mark answer keys. Designers send CLIENT REVIEW watermarks before print approval. The stamp is a social signal, not encryption. Anyone with an editor can remove it from a copy, so do not treat it as DRM.
Opacity defaults light on purpose. Raise it when the goal is to discourage casual screenshot sharing, lower it when readers must study fine print.
Huge files are limited by RAM because each page is rewritten. Split with PDF Split, watermark parts, and merge again if the browser struggles. Born-digital and scanned pages both receive the overlay.
Forms and links may survive, but interactive PDFs vary. Keep an unstamped original until you test clicks in the viewer your audience uses.
The PDF never leaves the tab during stamping. QuickConvert does not log document titles. Separate from that, the public site may load analytics, described alongside other tools in privacy with online file tools.
Export a Word brief with Office to PDF, stamp DRAFT, then email. Photograph evidence with Images to PDF, merge exhibits with PDF Merge, stamp CONFIDENTIAL on the combined packet for counsel.
If the stamped file overshoots an upload cap, PDF Compress may help when the PDF is photo-heavy. Text-only drafts often barely shrink; read how to reduce PDF size before you expect miracles.
Application packets sometimes want an unstamped signed page and a stamped working copy. Keep both filenames obvious so you do not upload the wrong one to a portal covered in the guide on assembling application PDFs.
Rotated pages inside the PDF are not auto-straightened. If the scan arrived upside down, fix the source image with your viewer’s rotate command, rebuild, then watermark the corrected export.
Short words such as DRAFT fit one diagonal line well. Long legal disclaimers may wrap and cover more area; shorten the phrase if readers complain about readability.
Compare file size before and after: a text overlay adds little compared with photo pages, so emailing the stamped draft should not blow past limits by itself.
No. PDF Watermark reads the file with pdf-lib, draws the text on every page in the tab, and downloads a new PDF. The bytes never leave your device. Use it on drafts that still contain personal data without sending them to a third party.
How to combine PDFs in order, what page content is copied, and what to check before you send the download.
How to tell a browser-side tool from an upload, and what QuickConvert still sends when your files stay on the device.
Rental, visa, job, and grant applications often want “one PDF”. Here is how to collect the pieces, turn photos into PDFs, merge them in order, and check the result.
What actually makes a PDF large, which QuickConvert preset to start with, and why a text-only file often will not shrink.
