Watermark any PDF directly from a URL
Append ?url= followed by a PDF link and the watermark tool opens with that file already loaded. PDFs are fetched server-side, so CORS rules don't apply and you don't have to download then re-upload.
How to use
Single PDF
The page loads, fetches the PDF on the server, and opens the watermark tool with the file pre-loaded — ready to configure and apply.

Multiple PDFs
Each PDF is fetched in turn and added to the batch. You configure one watermark, click Apply, and download the watermarked PDFs individually or as a single ZIP.

Server-side fetch · No CORS restrictions · 100% in your browser once loaded
Why use this URL-based entry?
Skip the upload step
When the PDF already lives on a public URL, point this page at it. The file is fetched in one round-trip — no download, no re-upload, no waiting.
No CORS restrictions
PDFs are fetched server-side, so the browser's CORS rules don't apply. URLs that won't load via JavaScript in a different tool will work here.
Batch watermark from URLs
Repeat ?url= for as many PDFs as you need. The same watermark is applied to every page of every PDF in one go.
Shareable and linkable
The URL is the session. Send it to a teammate and they land on the same PDFs ready to be watermarked — no manual file passing.
Fits into automated workflows
Hook this URL into a script, a no-code tool, or a CMS link and turn "PDF available somewhere" into "PDF watermarked and downloadable" in one step.
Same watermark experience
Once the PDFs are loaded, you get the full watermark tool — text or image, position, opacity, rotation, tile, page range. Just a different way in.
Build the URL
Start with /pdf/watermark-pdf/by-url, append ?url= and the full PDF address. Use &url= to add more.
The PDF loads automatically
The page fetches each PDF server-side and opens the watermark tool with them pre-loaded — no upload step.
Watermark and download
Pick text or image, set position, opacity, rotation, and pages. Click Apply, and download each watermarked PDF individually or as a ZIP.
- PDFs are never stored — fetched and forwarded in a single request.
