Merge PDFs online in your order, with bookmarks kept intact
Combine up to 100 PDFs into one, in exactly the order you arrange them — a drag-and-drop file list can be sent to this tool with no extra field, because the array order is the merge order.
Rotate files without the "rotate right does nothing" bug
Rotation here is relative, added to whatever rotation a file's pages already have, so a file already on its side actually straightens out instead of staying put.
Bookmarks are added automatically
The merged file gets a bookmark outline by default, with each source file as its own entry and that file's original bookmarks nested underneath it — or skip it entirely with one setting.
Mixed password-protected and open files? No problem
Password-protected files merge in alongside ordinary ones, just by naming the password on that entry.
Why you get a job ID, not the file, right away
Fetching and merging up to 100 files takes longer than a single web request allows, so this tool runs as a background job: submit it once, then poll for the finished PDF.
What you get
- Up to 100 PDFs combined into one, in your chosen order
- Automatic bookmark outline, or none if you turn it off
- Free, with nothing stored for longer than an hour
What's next?
Need to go the other way? Split PDF breaks a file back apart by range, page, or size. To drop a few pages from the merged file instead, Remove PDF Pages is the faster route, and Compress PDF can shrink the combined file if it's grown too large.
