About this tool
Merge PDF joins several PDF files into one document. It is useful when you need to send an application, bills, ID copies or assignment pages as a single file instead of many.
All pages from every file are kept in their original quality and in the order you choose. Nothing is re-compressed, so text stays sharp.
The merge happens inside your browser, so your documents are never uploaded to any server. Password-protected PDFs cannot be merged, so remove the password first.
Tips and common problems
- Check the order before you merge. The first file in the list becomes the first pages of the result.
- Number your files like 01, 02, 03 so they are easy to sort and add.
- Password-protected PDF? Remove the password in your PDF app first, then add it here.
- Check the page count shown after merging to be sure nothing is missing.
- Merged file too big to send? Make the pictures inside smaller before you make the PDFs.
Common questions
How many PDF files can I merge?
There is no fixed limit. Very large files use your device memory, so on a phone it is best to merge a few files at a time.
Can I change the order of the files?
Yes. Use the up and down arrows next to each file. The merged PDF follows the order of the list.
Why did one of my files fail?
The file is probably password-protected or damaged. Remove the password in your PDF app and try again.
Are my PDFs uploaded?
No. Everything runs on your own device and your files are not sent to us.
Merge PDF in detail
Why merge PDF files?
Applications often ask for one document, but your papers may be in several files: a form, a certificate, an ID copy and a bank statement. Merging them gives you a single PDF that is easier to send, easier to store, and less likely to be partly lost or opened out of order.
How the order works
The files are joined in the order shown in the list. Use the arrows to move a file up or down before you press Merge PDFs. Every page of every file is kept, so a three-page file followed by a two-page file gives a five-page PDF. Check the order twice, because the merged file is a new copy and your originals are not changed.
Keeping the file size reasonable
Merging does not recompress your pages, so the result is about as large as the files added together. If the merged PDF is too big for an upload limit, it usually means one of the files contains large scanned images. Scan again at a lower resolution, or turn pages into smaller images and rebuild them with JPG to PDF.
Protected and damaged files
PDFs that are locked with a password, or files that are damaged, cannot be merged. Open the file in a PDF viewer, remove the password if you are allowed to, save a fresh copy and try again.
Privacy
Your PDFs are joined on your own device. They are not uploaded, which makes the tool suitable for contracts, bills and ID documents.
