What this tool does
Combine multiple PDF documents in the order you choose. The tool processes supported PDF structures locally. Review form fields, annotations and signatures in the result.
Privacy, file support and limitations
Your document is read in the current browser tab and is not sent to our server. Files are not automatically saved for later recovery. Current limit: 60 MB per file; phone memory may impose lower practical limits. Browser PDF operations can affect advanced structure and digital signatures; do not use a modified PDF as though its existing signature remains valid.
Frequently asked questions
Do I need an account?
No. This tool is available without registration.
Will my PDF be uploaded?
No. The current implementation performs this operation locally in your browser. The page loads application code and libraries from our own domain, but does not upload the PDF bytes.
Can I use this for a confidential document?
Processing is local, but your device and installed browser extensions can affect privacy. Avoid untrusted browser extensions and verify the output before sharing.
