Merge PDF

Merge PDF

Stitch several PDFs into one continuous document.

Combine two or two hundred PDFs into a single file, in the exact order you want. Drag thumbnails to reshuffle, drop new files in mid-way, and export one clean PDF with a shared table of contents.

Files auto-deleted within 1 hour · no signup for basic use

How it works

Four calm steps.

  1. 01

    Drop your file

    Drag every PDF you want in the final file onto the upload card, or click to pick it from your device. You can also paste a link to a file hosted online.

  2. 02

    Arrange the pages

    Drag thumbnails to reorder documents. You can also mix in individual pages from larger PDFs instead of the whole thing.

  3. 03

    Preview before you commit

    Check the outcome in the browser first. Reorder, remove, or re-run with different settings – nothing is final until you press download.

  4. 04

    Download the result

    Save the merged PDF to your device, share a temporary link, or send it straight to Google Drive or Dropbox. Files are wiped from our servers within one hour.

Why Merge PDF

Built to be the last merge pdf tool you try.

No page limits on Pro

Free merges up to 20 files at once; Pro accepts as many as you can upload.

Quality that holds up

Bookmarks, outlines and page labels from the source PDFs are preserved in the merged file.

Private by default

Uploads travel over TLS, files are encrypted at rest, and every trace is deleted within 60 minutes. We do not read, index, or train on your documents.

No signup required

The free tier handles most day-to-day work. You only create an account if you want history, larger files, or batch automation.

FAQ

Questions people ask.

Can I merge PDFs with different page sizes?

Yes. We keep each page at its native size by default, or optionally normalise everything to A4 or Letter.

Are bookmarks kept?

Yes. Each source file's outline is nested under a top-level bookmark named after the file.

Is PDF Books Lib really free?

Yes. The free tier covers everyday use – you can merge several files per hour without an account. Pro unlocks larger uploads and batch jobs.

What happens to my files?

They live in an encrypted staging area for at most one hour, then they are permanently deleted. Nobody on our team can browse them.

Do I need to install anything?

No. Everything runs in your browser against our servers – Windows, macOS, Linux, iOS and Android are all supported.
