Merge & split PDFs
Add your PDFs, then drag pages into any order, rotate or delete them, and either merge into one file or split however you like. Nothing is uploaded.
Files are processed in your browser and never uploaded.
How to use Merge & split PDFs
Add your files
Drop one or more PDF files onto the upload area, or tap the area to choose them from your device.
Run it
Press Merge to one PDF, Don. The button stays disabled until there is something to work on, and each file shows its own progress and result.
Start over any time
Nothing is saved on a server, so reloading the page clears everything.
What this tool does
Merge multiple PDFs into one
Add as many PDFs as you like and they are joined in the order you arrange them, into a single file.
Visual page thumbnails
Every page is shown as a thumbnail, so you are working with the document you can see rather than a list of page numbers.
Reorder pages by drag or arrows
Drag a page to a new position, or use the arrows, and the order in the finished file follows what is on screen.
Rotate and delete pages
Rotate a page that was scanned sideways, or delete the blank one at the end, before you export.
Split into each page, every N pages, custom ranges or selected pages
Split into one file per page, every N pages, custom ranges like 1-3,7-9, or just the pages you selected.
No upload, no sign-up
The PDFs are opened, rearranged and written by your browser, so contracts and statements never leave your device.
Frequently asked questions
Are my PDFs uploaded anywhere?
No. Every PDF is opened, merged and split inside your browser on your device, and nothing is ever sent to a server.
What can I do here?
Add several PDFs and see every page as a thumbnail in one grid. Reorder pages by dragging or with the arrows, rotate or delete any page, then either merge everything into one PDF or split by each page, every N pages, custom ranges, or just the pages you select.
Does merging or splitting reduce quality?
No. Pages are copied across exactly as they are, so there is no re-compression and no quality loss. To make a PDF smaller, use the Compress PDF tool instead.
Can I reorder pages across different files?
Yes. Every page from every PDF you add appears in the same grid, so you can drag pages into any order, mix files, and remove pages before merging.
How big a document can it handle?
Everything runs on your device, so very large or many-page PDFs depend on your computer's memory and speed. On older phones or low-memory devices, work with smaller files or fewer pages at a time.
