Bind PDFs
Combine files into one document with a cover page and contents.
Merge several PDFs into a single bound document with a generated cover page listing every file and its page range. Page content is copied without re-rendering, so text stays selectable.
Your files are processed locally in your browser. Nothing is uploaded to a server, ever.
Tip
Drop your file here or click to browse. Everything is processed on this device — nothing is uploaded.

Frequently asked questions
Common problems and fixes
- The download button does not do anything
Why: some browsers block programmatic downloads after inactivity, or the disk is full.
Fix: allow downloads for this site in the browser settings, then process again — the job itself is instant for small files.
- Pages end up in the wrong order
Why: the selection order differed from the thumbnail order shown on screen.
Fix: re-check the page order in the preview list before running the job; the tool applies exactly what is shown.
- The output file will not open in my viewer
Why: the download was interrupted, or the viewer is very old.
Fix: download again and check the file size matches; if it persists, try a different PDF viewer.
