Organize PDF, in your browser.
Sort, add and delete PDF pages. Drag and drop the page thumbnails and sort them in our PDF organizer — then download the result. Nothing is uploaded, it all happens on your device.
Add your PDFs
Pick one or more files, or drag and drop them onto the page. You can keep adding more PDFs at any time.
Reorder, rotate, delete
Drag thumbnails to sort pages. Use the red icons on each card to rotate, insert a blank page, or delete.
Download
Click build. The new PDF is generated in your browser and offered as a download — no server involved.
Why client-side?
Private by default
Your files never leave your device. There's no server to send them to.
No signup, no watermark
No accounts, no email, no paid tiers, no logo stamped on your output.
Mix and match
Drop several PDFs and the organizer treats them as a single sequence — perfect for stitching chapters from different files.
Original quality
Pages are copied directly from the source. Text, images, and forms are preserved exactly.
FAQ
Are my PDFs uploaded anywhere?
No. The organizer runs in your browser using pdf-lib. The files stay on your device.
Can I add blank pages?
Yes. Use the red rotate menu on any thumbnail to insert a blank page before or after it. Blank pages inherit the size of the page next to them (or A4 if you start from scratch).
Does rotating a page change the original PDF?
No. Rotations are stored as part of the new PDF being built. Your source files are never modified.
What about encrypted PDFs?
The organizer tries to read encrypted PDFs in compatibility mode. Files with a real password will be skipped with an error message.
How does sorting work?
The ascending / descending buttons reorder pages by their original page number, grouped by the file they came from. Use drag and drop to fine-tune.
