PDF Watermark — Add Text & Image Watermarks

Upload a PDF and get a watermarked copy. Server-side processing (PHP + FPDI/TCPDF). No heavy client dependencies.

No file selected.
Tip: keep text short. To use an image logo, leave this field empty and upload a PNG to the 'Logo' field below.
If a logo is provided, the server script will use logo instead of text. Keep PNG < 1 MB for best performance.

By uploading you agree that you own the rights to the files. Files are processed on the server and can be auto-deleted after download by your PHP script.
How it works
  1. Upload a PDF and enter text or a logo.
  2. Form posts to watermark.php (server-side).
  3. PHP script uses FPDI/TCPDF to place watermark and returns the watermarked PDF for download.
