## FAQ

### How many copies can I create at once?

You can create between 1 and 20 copies of a PDF in a single operation. Each copy gets its own custom filename.

### Does duplicating modify the PDF content?

No. Each copy is an exact byte-for-byte duplicate of the original. Only the filename changes — no content, formatting, or metadata is altered.

### Are my files secure when using this tool?

Absolutely. All processing happens locally in your browser using JavaScript. Your PDF is never uploaded to any server, making it safe for confidential documents.

### What file format is the download?

If you create 2 or more copies, they're packaged as a ZIP file. A single copy downloads directly as a PDF.

### Can I use special characters in filenames?

Characters like / \ : * ? " < > | are automatically stripped for cross-platform compatibility. Letters, numbers, hyphens, and spaces all work fine.
