Runs locally — your files are never uploaded

Merge & split PDF

Combine a bundle into one file, or pull pages out into their own. People merge PDFs to assemble a mortgage application, a visa file, a contract with its annexes — and every other merge site takes the whole bundle onto their servers. This one doesn't.

Three separate PDF files combining into a single twelve-page PDF — A bundle into one file, or one file into its pages — nothing uploaded

Why merge and split PDFs here?

Never uploaded

The bundles people assemble are applications and contracts — the paperwork you'd least want sitting in a stranger's queue. Nothing here leaves your device.

No quality loss

Pages are copied whole, not re-encoded. Text stays selectable, images keep the exact bytes they had, and file size doesn't balloon.

No limits

No cap on how many files you merge, no daily quota, no sign-up and no watermark — because there's no server bill to pay for.

Merging and splitting without touching the pages

Why this is lossless and fast

A PDF is a tree of objects with a page list at the top. Each page points at its own content stream — the drawing commands — plus the fonts and images it needs. Merging two documents means building a new tree whose page list references the pages of both; splitting means building trees that reference a subset.

The content streams themselves are copied byte for byte and never decoded. Nothing is re-compressed, nothing is rasterised, no image is re-encoded. Text stays selectable because it is the same text objects; a scan keeps exactly the JPEG it arrived as. This is also why it is quick even on large files: the work is proportional to the number of objects, not to the number of pixels.

It is worth knowing what that implies about size. A merged file is roughly the sum of its inputs, because all the content is still there. Merging is not a way to make documents smaller, and any tool that shrinks a merged PDF noticeably has re-encoded something.

Page ranges, and why bad ones are refused

Ranges are written the way people write them: 1-3, 5, 8- gives three files, and the open-ended 8- means page eight to the end. Each range becomes its own document, so you get one file per range rather than one file with the pages you chose.

A range that runs past the end of the document is rejected rather than quietly trimmed. Silently clamping 1-99 to 1-20 would hand you a file that looks complete and is missing everything you asked for beyond page twenty — a mistake you would find much later, when the submission was already sent.

Encrypted files

A password-protected PDF is refused when you add it, and says so. That is deliberate: the alternative is discovering the problem partway through a merge, with an output file that is missing one input. Open it in a PDF reader, remove the protection, and add it again.

Frequently asked questions

Is merging and splitting PDFs free here?

Yes — free, unlimited, no sign-up and no watermark. No cap on how many files you merge and no daily quota, because there is no server bill behind it.

Are my PDFs uploaded to a server?

No. Both operations run in your browser and nothing is transmitted. The reason people merge PDFs is to assemble a submission — a mortgage application, a visa file, a contract with its annexes — and that is precisely the bundle you would not want sitting in someone else's processing queue.

Does merging reduce quality or make the file huge?

Neither. Pages are copied whole between documents without touching their content, so nothing is re-encoded or rasterised. Text stays selectable and images keep the exact bytes they had — the merged file is essentially the sum of its parts.

How do I choose which pages to split out?

Type ranges like 1-3, 5, 8- and you get one file per range; '8-' means page 8 to the end. Leave the box empty and every page becomes its own PDF. A single range downloads as one file, several arrive as a zip.

Can I reorder the files before merging?

Yes — drag the rows. The merged document follows the order shown on screen.

Can it open password-protected PDFs?

No. An encrypted PDF is rejected when you add it, with a message saying so, rather than failing silently partway through. Remove the password in a PDF reader first.
