Merge PDF

How to use

1. Drop in the PDFs you want to join, or click to choose them. The order you pick them is the page order.
2. Check the list and the order. Remove any file you didn't mean to include.
3. Press Merge PDFs and download the result.

FAQ

Does merging reduce quality?

No. The pages aren't re-rendered as images; the document structure is copied as is. Text stays text, so search and copy still work, and the file size is usually close to the originals added together.

How do I change the order?

The order you pick the files is the page order. To change it, remove them from the list and pick them again in the order you want. Prefixing filenames with 01, 02 also keeps things in order when you select them all at once.

Can it handle password-protected PDFs?

No. Encrypted files can't be opened, and we tell you that rather than producing something empty. Try again with a copy that has the password removed.

How many can I merge?

Up to 20 files and 100MB in total per go. For more, merge in two passes. Merging an already merged file again gives the same quality.
