Frequently Asked Questions
- Is there a limit on how many PDFs I can merge?

- Does merging affect PDF quality?
- No, pages are copied as-is into the combined file, so the quality stays identical to the originals.
- Can I change the merge order?
- Yes. Use the up and down arrow buttons on each file to reorder them. Files are merged from top to bottom.
- Can I use password-protected PDFs?
- Encrypted PDFs may not be processable in the browser.
- Is my PDF data sent to a server?
- No, all processing happens locally in your browser. No PDF data is ever uploaded to a server.
