Merge PDFs directly from their URLs
Pass one or more PDF URLs via ?url= and the merger fetches them server-side, ready to combine — no manual upload needed. Works with any publicly accessible PDF, regardless of CORS.
How to use
Single PDF
The page fetches the PDF server-side and opens the merger with it pre-loaded — ready for you to add more files or merge immediately.

Multiple PDFs
All PDFs are fetched and loaded into the merger in the order the ?url= parameters appear — drag to reorder, then merge.

Requirements
| Protocol | http:// or https:// only |
| Content-Type | application/pdf or application/octet-stream |
| Source | Any publicly accessible URL |
Server-side fetch · No CORS restrictions · Files never stored
Why use the URL entry point?
Skip the upload step
When your PDFs are already hosted somewhere, pass their URLs directly and skip the file picker entirely. The merger opens with your files pre-loaded.
No CORS restrictions
The server fetches the PDFs on your behalf, so browser CORS restrictions are irrelevant. Any publicly accessible URL works.
Merge multiple PDFs from URLs
Repeat ?url= as many times as you need. All the PDFs load in order, ready to merge into one file.
Shareable merge sessions
The URL is the session — share it and your teammates open the exact same set of PDFs in the merger, in the same order.
Fits into automated workflows
Generate the by-url link programmatically and embed it in dashboards, emails, or internal tools. Users click and merge without ever touching a file picker.
Same merger, different entry point
Once the PDFs are loaded, you get the full merger experience — reorder files, rename the output, merge and download.
Build the URL
Start with /pdf/merge-pdf/by-url, then append ?url= followed by each PDF's address.
The PDFs load automatically
The page fetches each PDF server-side and opens the merger with all files pre-loaded in the order you specified.
Reorder and download
Drag files into the order you want (or keep the URL order), click "Merge PDFs", and download your combined file.
- PDFs are never stored — fetched and forwarded in a single server request.
- URLs and PDF contents are not logged, inspected, or retained.
- No sign-up needed — construct the URL and go.
