About the PDF Merge Tool
Combine several PDF files into one document, in the order you choose. Add files by dropping them in or browsing, drag the cards to reorder, then merge and download. Everything runs in your browser — your files are never uploaded to a server.
Common use cases
- Reports: stitch chapters or sections into a single deliverable.
- Records: combine invoices and receipts for archiving.
- Presentations: merge slide exports into one handout.
How it works
- Drop or select two or more PDF files.
- Drag the cards to set the order.
- Click Merge PDFs, then download the result.
Frequently asked questions
Are my PDFs uploaded?
No. Merging happens entirely in your browser using pdf-lib — your files never leave your device.
Is there a file limit?
There’s no fixed cap, but very large files are limited by your device’s available memory.
