Frequently asked
- What does Folio do?
- It's a complete PDF app for Mac, iPhone, and iPad: rearrange pages, search documents, fill forms, add notes, sign, and export. See the Folio page.
- Can I reorder or remove pages?
- Yes. Rearrange, rotate, remove, and combine pages in a visual overview, then export the result.
- Can I search a scanned PDF?
- Yes. Folio recognizes text in scanned pages with local OCR, so you can search the whole document.
- Can I sign documents and fill in forms?
- Yes. Create and place signatures, fill out form fields, and export the finished document.
- Are my PDFs uploaded anywhere?
- No. Folio works locally on your device — your documents and signatures stay yours. See the Folio privacy policy.
- I found a bug. How do I report it?
- Email support@error404.nl with what you were doing, what you expected, and what happened instead. Screenshots help.
- How do I request a feature?
- Same address. Tell us what you're trying to do, not just the feature you have in mind — it usually leads to a better fix.
