🔒 Every tool runs in your browser — the files and values you enter are never uploaded to any server. How it works

PDF Tools

Merge, split, rotate and build PDFs — in your browser's memory, not on someone's server. The documents people run through PDF tools are contracts, IDs and records; here they never leave your device, and every operation is structural, so quality is untouched.

Handle documents privately

Merging, splitting and rotating PDFs is the kind of task where uploading is genuinely risky — contracts, statements, medical forms and IDs are exactly the documents that shouldn't sit on a stranger's server. These tools use the pdf-lib library in your browser, so pages are rearranged on your own device and the file is never transmitted.

Combine several PDFs into one, pull out a range of pages, or fix a sideways scan — then download the result, which is assembled locally. Nothing is uploaded, and the tools keep working with your connection off.

Frequently asked questions

Why does local processing matter most for PDFs?

Because of what PDFs are: contracts, IDs, tax forms, medical records, signed agreements. Free "upload your PDF" sites receive exactly the documents people should share least. These tools parse and rebuild PDFs in your browser's memory — disconnect from the internet and they work identically.

Do these tools reduce PDF quality?

No — merging, splitting and rotating are structural operations that copy or annotate page objects without re-rendering them. Text stays selectable, vectors stay sharp, images keep their original compression.

Can I work with password-protected PDFs?

Not directly — encrypted PDFs can't be parsed without their password. Open the file in your PDF viewer with the password, save an unprotected copy, then use the tools.
