Frequently asked
Does it re-encode my PDFs?
No. Pages are copied byte-for-byte. Text, fonts, and images are exactly as they were in the source files. If you want size reduction too, run the merged result through the Compress PDF tool.
Can I merge more than two PDFs?
Two-file merging today. We're adding 3- and 4-file merging as a follow-up — drop a note via the contact link if it's blocking you.
Are my files private?
Files are encrypted in transit, processed on our servers, and auto-deleted within 1 hour. We never train AI on your documents.
Will the resulting PDF have proper bookmarks?
Outline (bookmark) trees from the source files aren't carried over in v1. The merged PDF has clean pages; we can ship bookmark preservation later if it's useful.
What's the max file size?
50 MB per file on the free tier. So you can merge two 50 MB files into one 100 MB result.
