FAQ
- Are PDFs uploaded to a server?

- How do I specify pages to extract?
- Use comma-separated values and ranges, e.g. 1, 3-5, 8.
- Can I merge more than two PDFs?
- Yes. Select multiple files when merging and they are combined in the order you choose.
- Is there a file size limit?
- Limits depend on your browser memory. Very large PDFs may be slow but are not sent anywhere.
