Merge PDF
Several files into one, in the order you want.
Combine contracts, scans, invoices or book chapters into a single PDF. Add as many files as you need, drag them into the right order, and download one clean document.
The merge happens entirely in your browser — your files are never uploaded anywhere, which also means there is no queue and no file-count limit.
How it works
Drop two or more PDF files into the box above.
Arrange them in the order you want with the arrows.
Click “Merge files” and save the combined PDF.
Why this tool
No file limit
Merge two files or two hundred — nothing is capped, because your own browser does the work.
Order under your control
Reorder files before merging; page order inside each file is preserved exactly.
Original quality
Pages are copied, not re-rendered: text stays sharp and selectable, bookmarks of pages intact.
Frequently asked questions
Is there a limit on the number of files?
No. The merge runs on your computer, so the only practical limit is your device’s memory — hundreds of typical documents are fine.
Will the quality drop after merging?
No. Pages are copied into the new file as-is, without re-compression or rasterization. Text remains selectable.
Are my files uploaded to your server?
No. This tool runs fully in your browser. You can switch off the internet after the page loads and it will still work.
Can I mix page sizes and orientations?
Yes. Each page keeps its own size and orientation — A4 and letter, portrait and landscape can live in one file.
