- Order files with the move buttons. All pages of the first file come before the next.

- Encrypted documents and interactive forms are unsupported. Use unsigned copies; annotations and links are removed; signatures, bookmarks, attachments and accessibility features may not survive.
A few useful answers
Are PDFs compressed or sensitive information removed?
No. This organizes pages; it is not compression, redaction or security sanitization. Sensitive text and information within copied page content may remain.
What about large or unsupported files?
Unsupported files are rejected and processing has a time limit. Try a smaller, ordinary unencrypted copy. Passwords are never bypassed and no external conversion service is used.
Do files leave my device?
No. Files are read and processed in your browser. Names and contents are neither transmitted nor stored. Clearing cancels processing and removes the result.
