PDF Merger
Combine several PDFs into one file, in the order you choose.
One file instead of five
Paperwork has a habit of arriving in pieces — a contract in one PDF, its appendix in another, a signed page scanned separately. Merging stitches them into a single document so you can send one attachment instead of a confusing bundle, and so the pages read in the right sequence from start to finish.
Drop the files in, drag them into the order you want, and export one combined PDF.
Order is everything
The one thing worth double-checking before you export is the sequence. It is easy to end up with the appendix before the contract or the cover page in the middle. Arrange the files deliberately, and remember the pages keep their original text and quality — merging copies them across untouched rather than flattening them into images.
How to merge PDF files
- Drop in every PDF you want to combine — add as many as you need.
- Drag the files into the exact order you want them to appear.
- Click merge and download the single combined PDF.
When merging beats attaching
Sending one clean PDF instead of five separate attachments is the difference between a reply and a confused email thread. Merging is the go-to for assembling a contract with its appendices, combining scanned receipts for an expense claim, or turning a set of chapters into one book.
Because the pages are copied across rather than re-rendered, any text stays selectable and searchable, and bookmarks inside each source file are preserved where possible — so the merged document behaves like one that was authored together.
Frequently asked questions
Is there a limit to how many PDFs I can merge?
There is no fixed limit; you are only bound by your device's memory. Very large batches of big files may be slower because everything is processed locally.
Will the file size balloon after merging?
The merged file is roughly the sum of the originals. If that is too big, run it through the PDF compressor afterwards.
Can I merge password-protected PDFs?
You will need to remove the password first, since an encrypted file cannot be read for merging.
Can I choose the order of the merged files?
Yes. Arrange them however you like before exporting, and the combined PDF follows that order.
Does merging reduce quality?
No. The pages are copied across as they are, so text stays sharp and searchable.
Are my PDFs uploaded?
No. The merge happens entirely in your browser.
