Merge PDF
Combine multiple PDFs into one document, in the order you choose.
How to use Merge PDF
- Drop in every PDF you want to combine, or click to pick them from your device.
- Drag the rows into the order you want. The numbered badge shows where each file will land.
- Check the running total — each row lists its size and how many pages it contributes.
- Press Merge PDFs and the combined document downloads straight to your device.
How Merge PDF works
Add every PDF you want to join, then drag the rows into the order you want. Each row shows the file name, its size and how many pages it contributes, so you can confirm the running order before creating the merged document.
Pages are copied without re-encoding, so the merged PDF keeps the exact quality of the originals — text stays selectable, fonts stay embedded and images are untouched.
If one file turns out to be corrupt it is skipped and reported, and the rest are still merged. You never lose a whole job to a single bad file.
Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely inside your browser — the file is read from disk by the page and never transmitted. It keeps working even if you disconnect after the page has loaded.
How do I control the order of the documents?
Drag any row up or down; the numbered badge shows where that file will land. Keyboard users can focus a row, press Space, move with the arrow keys, then press Space again to drop it.
Does merging reduce quality?
No. Pages are copied as-is with no recompression, so the merged file is essentially the sum of its parts.
Can I merge password-protected PDFs?
Files that merely declare encryption with an empty owner password usually work. A PDF that truly requires a password to open cannot be merged — remove the protection first.
