What you can do here
Three of the most common PDF chores, without installing software or uploading anything. Merge combines several PDFs into one in the order you choose — use the up/down buttons to arrange them first. Extract / split pulls a page range (like 1-3, 5) out of a PDF into a new file, leaving the original untouched. Rotate turns every page of a PDF by 90°, 180°, or 270° to fix a scan that came in sideways.
Nothing is re-rendered
An important quality point: merging and extracting copy pages exactly as they are. Your text stays selectable and searchable, and no image is recompressed, so there's zero loss of quality — unlike the "print to PDF" trick that flattens everything. (If your goal is a smaller file rather than reorganising, use the PDF compressor instead.)
Why doing it locally matters
The PDFs people most often need to merge, split, or rotate are the sensitive ones — a signed contract, an ID scan, a medical form, financial statements. Free "PDF merge" websites upload those to a server you don't control. Here, the files are read and rewritten entirely inside your browser using pdf-lib, with no upload at any point. You can confirm it yourself — watch the Network tab or work with the connection switched off. The merge & split guide explains each operation in more depth.
Frequently asked questions
Are my PDFs uploaded?
No. Everything runs in your browser using pdf-lib. The files never leave your device.
Does merging reduce quality or lose text?
No. Pages are copied as-is, so text stays selectable and nothing is recompressed.
How do I extract specific pages?
Choose "Extract / split," then type the pages you want — for example 1-3, 5 — and download the new PDF.
Can it open password-protected PDFs?
It can handle some restricted PDFs, but a PDF locked with an open password must be unlocked first. Very large files are limited by your device's memory.
