About Merge PDF
Combining PDFs is the most common thing people need to do with a document, and it should not require an account or a desktop app. Add your files, drag them into the order you want, and download a single merged document.
Merging happens entirely inside your browser. Nothing is uploaded, which means there is no waiting on a connection and no copy of your document sitting on someone else's server. Page quality is untouched: pages are copied across exactly as they are, with no re-encoding.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
You can merge as many PDFs as your browser can hold in memory. In practice a few dozen files of up to 100 MB each works comfortably.
Can I change the order of the files?
Yes. After adding your files, drag them into the order you want, or use the up and down buttons on each row for keyboard access.
Do my files get uploaded to a server?
No. Merging runs entirely inside your browser, so your documents never leave your device.
