Merge PDF
Combine two or more PDF files into a single PDF, right in your browser. Add files, reorder them exactly how you want the merged document to read, then download the result - nothing is uploaded to a server.
Combine any number of PDFs
Add as many PDF files as you need - they're merged into one document in the order shown in the list.
Reorder before merging
Use the up/down controls to arrange files in the order you want them to appear in the final PDF.
Fully private
Merging happens entirely in your browser using pdf-lib - your files are never sent to a server.
Common Mistakes to Avoid
Adding files in the wrong order
Solution:
Check the file list and use the reorder arrows before clicking Merge - the output follows the list order exactly.
Trying to merge a password-protected PDF
Solution:
Password-protected PDFs can't be read in the browser without the password - remove protection first if needed.
