Merge PDF

Processed in this browser

File limit: 32 MB

This tool never uploads your input.

Drop a file

Drop a file here or choose one.

Sample workflow: choose a PDF on this device, then Process. The file stays in this tab.

This step may download a library in this browser the first time you use it.

Concatenate PDFs in this tab in the order you drop them so a portal or inbox gets one file instead of twelve. Password-protected inputs may fail, and a stack of scans can still blow Gmail’s 25 MB send limit.

A school portal, visa pack, or hiring form wants one PDF, not a zip of twelve. That is the job: put existing PDFs in order and download a single file, without sending the packet to a merge service.

This page concatenates PDFs in the current tab. It does not turn a folder of photos into a PDF — that is images to PDF. It does not shrink the result. Merged camera scans are often larger than any one input.

When one file is the actual requirement

  • Job or school uploads that reject a second attachment.
  • Receipts plus a cover letter that must travel together.
  • A contract addendum you will not upload “just to combine,” even if the brand deletes the cloud copy in an hour.

Drop files in the order you want them read. Mixed page sizes (A4 plus a landscape phone scan) stay mixed; we do not normalize paper.

How to use it

  1. Choose two or more PDFs from this device.
  2. Check the order. Process in this tab.
  3. Download the combined PDF. If Gmail offers a Drive link instead of a real attachment, the file is still too heavy.

Typical ceiling is about 32 MB for what the tab can hold. That is tight for a stack of full-resolution scans.

After the merge

Zipping the merged PDF almost never helps email. The inbox still sees one fat binary.

FAQ

Can I merge photos and PDFs in one drop?

This tool joins PDF files only. Turn JPGs or PNGs into a PDF first, then merge that file with the rest of the packet.

Will bookmarks and forms survive?

Treat the result as a new concatenated document. Interactive forms, some bookmarks, and encryption often do not carry over cleanly.

The merged file is too big for Gmail. What now?

Personal Gmail sending is 25 MB for the whole message. Base64 encoding adds roughly a third, so many people aim nearer 18–20 MB of raw files. Compress scan-heavy PDFs, or split the packet across messages.

Why did a file fail to merge?

Password-protected, corrupted, or huge files often fail in the tab. Unlock or repair the source elsewhere; this page cannot crack a password.

Is this the same as rearranging pages in one PDF?

No. Merge builds one file from several. To rotate, delete, or reorder pages inside a single PDF, use organize PDF.

Does any file get uploaded?

No. Concatenation stays in this browser tab. Typical total ceiling is about 32 MB — a twenty-scan binder may not start.
