PDF Merger
Combine multiple PDFs into one in the order you choose, no quality loss.
Upload up to 20 PDFs, drag them into the right order, and we join them into a single PDF. Pages are kept exactly as they were, no re-rendering, no quality loss. Get the combined file by email.
How it works
- Upload your PDFs (up to 20, 25 MB each).
- Drag them into the order you want them joined.
- Unlock the result and download the combined PDF.

Frequently asked questions
How many PDFs can I merge at once?
Up to 20 PDFs, 25 MB each. If you have more, merge in batches: combine the first 20 into one, then merge that file with the next batch.
Will the quality drop after merging?
No. We do not re-render or re-encode any pages. Each page is copied byte-for-byte from your input, so text, images, and vector graphics are identical to the originals.
Can I change the order before merging?
Yes. After upload, each file appears in a numbered list with up and down arrows. Drag the order to whatever you like before continuing.
Do bookmarks and form fields survive the merge?
Page content (text, images, vectors) is preserved exactly. Bookmarks, anchored cross-file links, and form fields are not carried across files. If you need a fillable merged form, fill the forms before merging.
How long are my files kept?
Your uploaded PDFs and the merged output are auto-deleted after 7 days. Re-download is available during that window via the secure link.
