PDF Merge — free online tool
Combine scanned receipts, contracts, or lecture notes in the order you choose—pages never leave your machine during merging.
When to use PDF Merge
Combine signed pages, scanned receipts, or chapter PDFs into one attachment for email or e-filing.
Keeps drafts on your machine instead of sending contracts to unknown servers.
What PDF Merge does not do
Cannot unlock password PDFs or OCR scans. Page size mismatch is not auto-normalized.
How to use PDF Merge
- Click add files on PDF Merge and select multiple PDFs in the order you want.
- Reorder filenames if the UI lists them before merging.
- Press merge and wait for pdf-lib to finish in the tab.
- Download the combined PDF and open it locally to confirm page sequence.
Practical tips
- Arrange files in the exact reading order before merging—reordering after needs the PDF Rotate tool.
- Merging happens in your browser, so confidential contracts never leave your device.
- Combine scanned receipts into one PDF before attaching to an expense claim.
Example
Join a signed cover PDF with a scanned ID PDF into one attachment for e-filing.

Why did the PDF Merge fail or look wrong?
Try a smaller file, fewer pasted characters, or an updated browser. Extensions that block scripts or downloads sometimes interfere—test in a private window if results never appear.
Are my files uploaded when I use the PDF Merge?
No. The file is read in your browser tab and the result is generated locally. Nothing is sent to Webtoolshop servers for in-browser image or PDF tools.
