A few useful answers
Can I merge password-protected files?
No. Open and save an unencrypted copy using a trusted PDF application first. Formatixa does not remove passwords.
Will signatures and forms remain valid?
Merging changes the document. Signed PDFs and interactive forms are rejected in this version to avoid invalid signatures or missing form behavior.
Are bookmarks and attachments copied?
This tool combines pages. Document-level bookmarks, embedded attachments and other document features are not guaranteed to transfer. Keep your originals.
Do my files leave my device?
No file bytes are sent to a server. Processing and downloads happen in your browser. Optional Google Analytics measures page visits and tool usage only after you accept analytics. It does not receive your files or filenames. See the privacy and limits page for details.
