A PDF watermark is text or an image overlaid on every page of a PDF document — typically used to mark documents as "Confidential", "Draft", or to add company branding. Filator's watermark tool supports both text and image watermarks with 9 positions, adjustable opacity (0-100%), custom rotation, 3 fonts, and any hex color — all processed in your browser using pdf-lib.
Most PDF watermark tools — iLovePDF, Smallpdf, and Adobe Acrobat ($19.99/month) — upload your files to their servers. Filator processes everything locally, which is especially important when watermarking confidential documents.
All watermarking happens in your browser. Your PDF files never leave your device, unlike competitors that upload files to their servers for processing.
Process PDFs of any size without restrictions. No 50MB caps or 50-page limits like Sejda, and no 100MB maximums like iLovePDF's free tier.
No "3 tasks per hour" limits or daily caps. Watermark as many PDFs as you need, whenever you need them.
Start watermarking instantly with full access to all features. No account creation, email verification, or registration walls.
Best for document classification and status labels. Add "Confidential," "Draft," "Copy," "Do Not Distribute," dates, names, or custom messages. Text watermarks offer font customization, color control, and crisp rendering at any zoom level.
Ideal for branding and copyright protection. Upload your company logo, signature, stamp, or custom graphic. Supports PNG with transparency for professional integration with your document content.
Mark documents as "Confidential," "Internal Use Only," "Draft," "Copy," or "Sample" to control distribution and usage.
Add copyright notices, company logos, or "© 2025 Company Name" to protect intellectual property in shared documents.
Brand proposals, contracts, and reports with your company logo, tagline, or visual identity.
Label versions with "FINAL," "APPROVED," "PENDING REVIEW," or dates to track document status and revisions.
Adobe Acrobat Pro ($19.99/month) adds watermarks to PDFs, but it requires desktop software. Adobe's online tool uploads your file to their servers.
