Merged PDF
How it works
The browser parses each PDF locally, copies every page exactly once in the selected document order, preserves each document’s internal page order, and writes a new PDF with minimal generic metadata.
Limits and document features
Use 2–20 PDFs totaling no more than 100 MB and 500 pages. Complex forms, attachments, bookmarks, interactive features, and document metadata may not survive exactly. Merging signed PDFs generally invalidates their digital signatures. Encrypted PDFs are not supported.
