FAQ
- Do you upload my PDFs?
- No. Merging happens in your browser with pdf-lib. Files never leave your device.
- Is there a file size limit?
- There is no hard server limit, but very large PDFs may be slow or run out of memory on phones. Prefer files under ~50 MB on mobile.
- Will bookmarks and forms be preserved?
- Basic page content is merged. Advanced interactive features may not carry over perfectly.
