Merge PDF Files

Combine multiple PDF files into one document.

Upload 2–10 PDF files and get a single merged PDF back. Pages are combined in the order you upload them.

Merging PDFs is essential when you need to combine chapters, reports, contracts, or scanned documents into a single file for sharing or archiving. Our tool supports up to 10 PDFs per merge, and pages are combined exactly in the order you select them.

The merge uses pdf-lib, a pure-JavaScript library that copies page content faithfully without re-rendering. Embedded fonts, images, links, and vector graphics are all preserved from each source document.

For documents requiring more than 10 PDFs, merge them in batches: merge the first 10, then merge the result with the next set. There's no limit to how many rounds you can run.

How to use Merge PDF Files

Step 1: Click the upload area and select 2–10 PDF files, or drag them all in at once.
Step 2: Files will be merged in the order they appear in the list. Click "Convert now" to combine them.
Step 3: Download your single merged PDF containing all pages from every file you uploaded.
