Merge PDFs into one clean document
Contracts, annexes, scanned receipts, drop them in, put them in order, and get a single PDF back. Pages are copied as-is: no re-encoding, no quality loss.

Files stay private: PDFs and images are edited in your browser.
Lossless by construction
Merging copies pages without re-rendering them. Vector text stays vector, images keep their exact bytes, the output is bit-for-bit faithful.
You control the order
Add several files, arrange them the way you want, and merge. The combined document follows your order exactly.
Runs in your browser
All files are read and assembled locally. Merging a 200-page contract bundle never sends a single byte to a server.
Order first, then one file
Drop the files in, drag the cards until the order is right, merge. Pages are copied, never re-rendered.
Drag the cards, not the page numbers
Each file shows its first page, the document you already had open is badged Current, and Add file inserts another PDF from your computer. The merged result follows this order exactly.
Lossless by construction
Merging copies page objects into a new document instead of re-rendering them, so text stays vector and images keep their exact bytes.
Heavy bundle? Compress after
Five heavy annexes make one heavy PDF. On a 208-page, 93 MB document the recommended preset returned 63.2 MB.
One file for the road
Sending five attachments invites five chances for one to get lost. A single merged PDF opens the same way everywhere, prints in one job, and archives cleanly.
Because pages are copied rather than re-encoded, a merge is fast even on large bundles, most of the work is bookkeeping, not rendering.
Keep the result manageable
Merging several heavy files can produce a document that is awkward to email. If the combined size matters, run it through the Compress tool afterwards, the recommended preset typically shrinks image-heavy PDFs by more than half.
Need only part of the merged file later? The Split tool extracts page ranges or breaks the document at its bookmarks.

Frequently asked questions
No. Pages are copied losslessly into the new file, text stays selectable and images keep their original compression.
A PDF locked with an opening password must be unlocked first. Permission-only restrictions can usually be lifted with the Unlock tool.
No server limit exists because everything runs locally. Very large merges are bounded only by your device's memory.
