Merge & Split PDF
Combine multiple PDFs into a single file, or split one apart by page or range — all in your browser, nothing uploaded.
Drag and drop multiple PDFs, or click
PDF · No server upload
🔒 PDFs are processed entirely in your browser. Files are never sent to a server.
Merge and split in one workspace
Two modes share the same panel. In Merge, drag in as many PDFs as you need or click to browse, then set the exact order with the up and down arrows before combining everything into one file — the button shows a live file and page count so you know what you are about to produce. Each file lists its size and page count as it loads, so you can catch a wrong or empty document before you commit. In Split, load a single PDF and either break every page into its own document or pull out specific parts by typing ranges like "1-3, 5, 7-9". Output files are named by their page position (p1, p4-6); when a split yields several files they are bundled into one ZIP, while a single result downloads on its own.
Where it comes in handy
Merging shines when scattered documents belong together: fold a signed contract, its appendices, and a scanned ID into one file to email, stitch a month of invoices or bank statements into a single packet, or join slides and chapters that were scanned page by page. Splitting handles the reverse — extract one signature page from a long agreement, lift a single chapter out of an ebook, separate a double-sided scan into individual records, or carve out a page range to share without sending the whole document. Because reordering and range selection are built in, you rarely need a second app just to get pages into the right sequence, and the range field accepts several selections at once so a large PDF becomes many focused files in one pass.
Private by design, lossless output
Every merge and split runs on your own device through an in-browser PDF engine, so the files never reach a server — contracts, statements, and legal or medical scans stay on your machine. There is no daily quota, no sign-up, and no watermark stamped on the result. Pages are copied rather than re-rendered, which keeps text selectable, preserves the original resolution of fonts and images, and avoids any re-compression that would soften a scan. The one exception is encrypted PDFs: the browser generally cannot open a password-protected file, so remove the password before loading it. On the free plan you can merge up to five PDFs at once, while splitting and single-file work stay unrestricted.
Frequently asked questions
Are my PDFs uploaded anywhere?
No. Both merging and splitting happen entirely inside your browser using an on-device PDF library. The files are never sent to or stored on a server, and they clear from memory when you close the tab — so even sensitive contracts or statements stay on your machine.
How do I split out only certain pages?
In the Split tab, choose "split by page ranges" and type comma-separated ranges such as "1-3, 5, 7-9". Each range becomes its own PDF named by its page position; several results download together as a single ZIP, while one result downloads on its own. Choose "each page" instead to break every page into a separate file.
Does merging lower quality or add a watermark?
No. Pages are copied as-is rather than re-rendered, so text stays selectable and images keep their original resolution — nothing is re-compressed and no watermark is added. The only files that may not open are password-protected PDFs; remove the password first, then merge or split as usual.
