Combine several PDF documents into a single file. Each one is previewed with its page count, and you drag the rows to set the order before merging.

Every file is opened and its first page rendered as a thumbnail, with the page count shown. There is no guessing about which document is which.
Drag any row to move it, or sort everything alphabetically in one click. Numbering updates live so the result matches the list exactly.
Merging usually means combining invoices, medical records or signed contracts. Nothing here is uploaded, which is the only real guarantee.
Step by step
Drag several files onto the box or click to select them. A thumbnail and page count appear for each one.
Drag rows up or down, or use sort by name if your files are numbered. The position number updates as you go.
Press merge. The documents are combined in order and the finished PDF is saved to your device.
FAQ
There is no fixed limit. Because everything runs on your device, the practical ceiling is memory: a few dozen ordinary documents merge instantly, while combining several very large scanned files will be slower.
No. Merging copies the original page objects directly into a new document, so text stays selectable, images keep their original resolution, and nothing is re-encoded or degraded.
Only if the protection is an owner password restricting printing or copying, which is bypassed automatically. A document requiring a password to open must be unlocked first using the PDF unlocker.
Yes, exactly. Pages appear in the finished document in the order the files are listed, top to bottom. The number on each row is its position.
Internal page links within a document are preserved where the source file supports it. Outlines and bookmarks from the original documents are not carried over, which is a limitation of merging at the page level.
No. The files are read and the new PDF is assembled entirely inside your browser. Nothing is transmitted.
This tool lets you merge PDF files online into a single document, with no software to install and no upload. Add as many PDFs as you need, and each one is opened so you can see its first page as a thumbnail alongside its page count before you commit.
Order is set by dragging. Move any row up or down, or sort everything alphabetically when your files are numbered, and the position shown on each row is exactly where those pages will land in the result. This matters more than it sounds: most merging mistakes are ordering mistakes.
Unlike tools that rebuild pages as images, merging here copies the original page objects into a new document. That means no quality loss at all: text remains selectable and searchable, images keep their resolution, and file size stays proportional to the originals rather than ballooning.
Everything runs locally through your browser. That is the practical point rather than a slogan, because merging usually involves invoices, contracts, medical records or bank statements, which are precisely the documents nobody should be uploading to an unfamiliar server.
