About Merge PDF
Merging PDFs is the most requested PDF operation, and almost every free option online asks you to upload confidential documents to a server you know nothing about.
This tool loads each file into memory in your browser, copies the pages into a new document in the order you set, and hands you the result as a download. Nothing is transmitted.
Frequently asked questions
Are my PDFs uploaded?
No. Merging happens in your browser using a JavaScript PDF library. The files never leave your device.
Is there a file size limit?
Only the memory available to your browser tab. Very large scanned documents may be slow but generally work.
Are bookmarks and forms preserved?
Page content, images and text are preserved. Interactive form fields and bookmarks are not carried across.
