FAQ
Are PDFs uploaded?
No. Merging is done entirely in your browser, and files are never uploaded to any server, making it safe for sensitive documents.
Are there page or file size limits?
There are no artificial page limits; individual files should be ≤ 100MB for smooth browser performance. The merged result has no watermarks.
Can I adjust the merge order?
Yes. After adding files, use the up/down buttons on each line to sort them; they will be merged in the final list order.
Can encrypted PDFs be merged?
Unpassword-protected encrypted PDFs can usually be merged directly; PDFs with an open password must be decrypted first.
