Merged PDF ready
Key features
Choose two or more PDF files, reorder them with the up/down arrows, and merge them into a single PDF. The download starts automatically once merging finishes.
Every PDF is read, combined, and saved entirely on your device using an open-source PDF library, and files are never uploaded anywhere.
How to use
Choose your PDF files
Click to browse, or drag and drop two or more PDFs onto the box. Add more any time.
Put them in order
Use the up and down arrows next to each file to set the order they'll appear in the merged PDF.
Merge, then decide
Click "Merge PDFs" and review the result: preview it, download it, or start over if it's not right.
Frequently asked questions
Are my PDFs uploaded anywhere?
No. Files are read and combined entirely in your browser using an open-source PDF library. Nothing is sent to a server.
Is there a limit to how many files I can merge?
No hard limit is enforced, but very large or numerous files take longer and use more memory since everything is processed on your device.
Can I merge a password-protected PDF?
No. Encrypted or password-protected PDFs can't be read by the library this tool uses. Remove the password first using a PDF editor, then merge.
