How to merge PDFs

  1. 1. Drop your PDFs onto the page, or click to choose files.
  2. 2. Drag the file cards to set the order you want.
  3. 3. Click Merge. Your combined PDF downloads automatically.

When to use this

Combining a signed contract with its addendums. Stitching a receipt + statement + invoice into one file for an expense report. Merging scanned pages from different sessions into a single document. Anything where "here are three PDFs, send them as one" would save someone a click.

What happens to my files?

Nothing leaves your device. When you drop a file onto the page, it's loaded into your browser's memory and processed there. There's no server-side copy, no background upload, and no account. Close the tab and your files are gone from Paper entirely.

Limits

The free version handles files up to 25 MB, up to 30 pages per operation, and batches of up to 15 files. That covers most real-world documents. Paper Pro ($4.80 one-time) removes all limits — see pricing.
