How it works
To combine several PDFs into one file, drop them onto this page and put them in the order you want — the pages are copied across without re-encoding, so nothing loses quality, and the merge happens in your browser.
Merging copies the pages out of each document you add and writes them into a single new PDF, one after another. Nothing is re-encoded along the way, so the result is exactly as sharp as the originals — text stays selectable, images keep their full quality, and the file size is roughly the sum of what went in.
The order in the list is the order in the finished document. Use the arrows to move a file up or down before merging; this matters more often than people expect, since files picked from a folder arrive in whatever order the operating system hands them over, which is rarely the order you want.
This is the tool for assembling a signed contract from separately scanned pages, putting a report and its appendices into one file, or collecting receipts into a single submission. Because the work happens in your browser, there is no upload wait and no limit on how many files you combine beyond your device’s memory.
Bookmarks and form fields from the source documents are not carried across — the pages themselves are copied, but that surrounding structure is not. For plain documents, which is almost all of them, this makes no practical difference.
FAQ
Does merging reduce quality?
No. Pages are copied across as they are, with no re-encoding, so the merged file looks identical to the originals.
How do I control the page order?
Files merge in the order shown in the list. Use the up and down arrows to rearrange them before pressing merge.
How many PDFs can I combine?
There is no fixed limit, because nothing is uploaded. Your device’s available memory is the practical ceiling.
Can I merge a password-protected PDF?
Not directly. Remove the password first — an encrypted file cannot be read without it, and the tool will tell you if it encounters one.
Will the merged file be huge?
It is roughly the sum of the inputs. If that is too large to send, run it through the PDF compressor afterwards.
