PDF merging FAQ
Are documents uploaded when I merge PDFs?
No. Reading, page copying, ordering, and output generation happen locally in your browser. Document contents are not uploaded to RouteMarket.
How many PDFs can I merge?
You can currently add up to 20 PDFs, with a 100 MB limit per file and a 250 MB combined input limit. Larger jobs use more device memory.
Can I change the PDF merge order?
Yes. Drag file cards or use the left and right arrow buttons. The result is generated in the queue's left-to-right order.
Why can encrypted or password-protected PDFs not be merged?
The tool does not bypass document protection. Remove the password through an authorized workflow before adding the PDF.
