Merge PDF

Combine contracts, scans, invoices, or chapters into one PDF, in exactly the order you choose. Nothing is re-compressed, so every page stays crisp.

Private by design: This tool merges documents locally using an in-browser PDF library. Your files are not uploaded to a server, and nothing is stored or logged. See how in-browser processing works.

How to merge PDF files

Drop two or more PDFs onto the upload area.
Arrange them with the up/down arrows: the list order becomes the final page order.
Click Merge PDFs, then download the combined document.

Combine documents in the order you choose

The file list is your table of contents: the top document comes first, and the arrows rearrange everything before you merge. Contract plus annexes, chapters into a book, a semester of scanned notes, application forms with supporting documents: one ordered PDF beats a zip of loose files every time.

Nothing is recompressed

Pages are copied into the merged document exactly as they are, original quality, original dimensions, original orientation. Mixing A4 with Letter or portrait with landscape works fine; each page keeps its own geometry.

Merge, then tidy

Merged the right files but need to drop a few pages? Split PDF extracts exactly the pages you want to keep. Result over an upload cap? The PDF Compressor finishes the job. Step-by-step walkthrough: How to merge PDF files.

Good to know

All pages from each document are included, in list order.
Pages are copied without re-compression, so quality and page sizes are preserved exactly.
Password-protected PDFs need their password removed before merging.

Frequently asked questions

Can I change the order of the documents?

Yes, use the up/down arrows next to each file before merging. The file at the top comes first in the merged PDF.

Is there a limit on file count or size?

No fixed limit, merging happens on your device, so capacity depends on your browser's memory. Dozens of typical documents merge without trouble.

Will page sizes and orientations be preserved?

Yes. Each page keeps its own dimensions and rotation, so mixing A4, Letter, portrait, and landscape documents works fine.

Are my documents uploaded to a server?

No. Merging happens entirely in your browser: your documents never leave your device.

Are bookmarks and links preserved?

Page content is preserved exactly, but document-level extras like bookmarks/outlines don't carry into the merged file. Links printed on the pages themselves remain visible as text.

Can I merge password-protected PDFs?

No, remove the password first, then merge. Encrypted documents can't be read by the merger.

How many PDFs can I merge at once?

No fixed limit, dozens of typical documents merge comfortably; the practical ceiling is your device's memory.
