Merge PDF Free Online

How it works

Merge runs entirely client-side. We never receive your PDF contents for this tool.

1

Add PDFs

Drop two or more PDF files. Larger merges are limited by your device memory — aim under ~100 MB total for smooth runs.

2

Order pages

Arrange files in the sequence you need. The merged document follows that order from first to last.

3

Download one file

Processing uses pdf-lib in your tab. Nothing is sent to SortMyFile servers for merge.

When you’d use this

Contracts with annexures, multi-scan KYC packs, and chapter PDFs that must become one attachment — merge in order without a watermark or account wall.
