Limits and support
Up to 15 MiB per file, 30 MiB total, and 200 pages combined. Encrypted PDFs, forms, detected digital signatures, damaged files, and files that cannot be checked are rejected. Bookmarks and interactive features are not guaranteed to be preserved. Memory limits vary by device.
Questions
Can I merge signed or fillable PDFs?
No. When encryption, forms, or signatures are detected, the entire job stops. Use an unsigned, unencrypted PDF without form fields.
Will the original files change?
No. You download a new document. Source files remain unchanged. The result contains pages in the selected order; it does not promise to retain bookmarks or interactive data.
