PDF files — add two or more, then put them in order

Files are processed entirely in your browser — they're never uploaded to a server.

Next steps

Combine several PDFs into one file

Merge PDF joins two or more PDF files into a single document, with every page of each file in the order you choose. Pages are copied across as they are — nothing is re-rendered or recompressed — so text stays selectable and pages keep their original quality.

The files are combined inside your browser and the result is saved straight to your device, so contracts, bank statements and other private paperwork never leave your computer.

How to merge PDF files

Select your PDFs, or drop them on the upload area. You can add files in several goes; each new one joins the bottom of the list.
Check the page count shown under each file name. A file marked as password-protected or unreadable is left out of the merge.
Use ↑ and ↓ to set the order and × to remove a file. The top file becomes the start of the merged PDF.
Click the merge button, which shows what it will join — for example “Merge 3 PDFs (24 pages)”.
merged.pdf downloads straight away. Click Clear all to start a new merge.

What the merged file contains

Whole files, in list order. Every page of every file is included; to leave pages out, trim the source file first.
Unchanged pages. Text, images and page sizes are copied exactly, so a mix of A4 and Letter pages stays mixed.
Pages only. The merged file is a new document, so bookmarks and fillable form fields from the originals aren’t carried over.
A size check. The confirmation message gives the final page count and file size before you open it.
File name: always merged.pdf, so rename it to something meaningful before sending.

Common reasons to merge PDFs

Applications: send a CV, cover letter and certificates as the single upload many portals ask for.
Bookkeeping: gather a month of invoices or statements into one file for your records or accountant.
Reports: assemble chapters or appendices that were exported as separate PDFs.
Scanning in batches: join the parts of a long document your scanner saved as several files.

Tips before you combine files

Need only a few pages from one file? Extract them with Split PDF, then merge the extracted copy.
Have photos or scans as image files? Turn them into a PDF with JPG to PDF and add that to the list.
If the combined file is too big to email, run it through Compress PDF afterwards.
Wait until every file shows its page count before merging — large files take a moment to read.

Merge PDF: common questions

How many PDFs can I merge at once?

There’s no set limit; you need at least two. Because the work happens on your device, very large or numerous files depend on how much memory your browser has.

Does merging reduce the quality of my PDFs?

No. Pages are copied without being redrawn, so text, images and scans look exactly as they did in the original files.

Can I reorder individual pages, not just files?

Not here — the arrows move whole files. Split PDF’s Extract pages mode keeps pages in the order you type them, so “3, 1, 2” gives you a reordered copy you can then merge.

Why is one of my files marked as password-protected?

Encrypted PDFs can’t be combined, including some that open without a password but restrict editing. Open the file in a PDF app that can remove the protection, save an unprotected copy, then add it again.

Are my files sent anywhere when I merge them?

No. Your PDFs are read and joined in this browser tab, and merged.pdf is saved directly to your device.
