Watermarks deter unauthorized sharing and clearly mark document status. CrispPDF's Watermark tool lets you stamp text ("DRAFT," "CONFIDENTIAL," your name) or upload a logo—then customize opacity, angle, size, and position.
Apply the watermark to one page, selected pages, or the entire document. Preview the result before downloading. The workflow is instant and entirely browser-based, so your files stay private.
For coaching centers protecting study materials, a semi-transparent logo on every page discourages redistribution. For legal teams marking drafts before final review, a diagonal "DRAFT" stamp ensures no one mistakes the file for the approved version.
After watermarking, explore related tools: flatten the PDF to lock the watermark permanently, compress for email, or password-protect before sending.

// Why CrispPDF
CrispPDF runs entirely in your browser — your files never touch a server. No signup, no watermarks, no daily limits, no upsells. We built it because every other PDF site is slow, ad-stuffed, or hides the good features behind a paywall. CrispPDF is fast on a phone, fast on a laptop, fast on a 10-year-old machine. Output is byte-clean: signatures stay sharp, compressed PDFs stay readable, conversions preserve layout where the source allows. And because nothing leaves your device, even confidential documents are safe to process. Bookmark this page, share it with your team, and stop juggling five different PDF sites for five different tasks.
// FAQ
Upload the PDF, drag in your logo image, adjust opacity and position, and download.
Yes. Type 'DRAFT,' set low opacity, and tilt diagonally for a classic draft stamp.
Yes. CrispPDF is 100 % free—no signup, no watermark on the output itself.
Upload to CrispPDF, add text or a logo, customize appearance, and download.
Yes. Upload a PNG with transparency and lower the opacity slider as needed.
Type 'CONFIDENTIAL,' set the angle and position, and apply to all pages.
Add a diagonal text watermark such as 'COPY — NOT FOR REGISTRATION' or the recipient's name across every page. That marks circulated copies clearly without altering the original, and it discourages reuse of a scanned deed.
'DRAFT', 'PRIVILEGED & CONFIDENTIAL', or the matter number, applied to all pages at low opacity so the text stays readable. Flatten the PDF afterwards so the watermark cannot simply be deleted.
If you flatten the document after watermarking, the mark becomes part of the page content and cannot be selected or deleted in an ordinary PDF editor.
