Merge PDFs into one file
Combine contracts, invoices, chapters or scans into a single PDF. Files are joined in exactly the order you add them — nothing is silently re-sorted, because a merge tool that reorders your documents is a bug, not a feature.
The merge happens server-side with a proper PDF library (no re-rendering, no quality loss): pages are carried over losslessly, so text stays text and vector content stays sharp.
- 1
Add two or more PDFs — the order you add them is the order they merge.
- 2
Check the list; add more files if needed.
- 3
Merge and download the combined PDF.
Limits are honest and generous for real use: each file up to 25 MB, and the combined result respects the same 120-page cap that applies everywhere — the page total is checked before work starts, so you get a clear message instead of a half-built file.
Merged files live in your private workspace only and are permanently deleted within 24 hours, like everything else here.
Merge PDF — questions
Is there a file-count limit?
Up to 20 documents per merge, within the combined 120-page cap.
Does merging reduce quality?
No — pages are copied losslessly, not re-rendered. Fonts, vectors and images are untouched.
Can I reorder after adding?
Remove and re-add in the order you want, or use the full app where drag-to-reorder is available.
