27 PDF tools in one app. Merge, split, compress, convert, sign — plus AI that summarizes, extracts data, and chats with your documents.
Stop juggling five apps for one file format. Folio puts 27 PDF tools in your pocket — merge, split, compress, convert, sign, scan, and more.
CONVERT ANYTHING
Turn PDFs into Word, Excel, or image files. Go the other way too — photos, documents, and spreadsheets become clean PDFs in a tap.
MERGE & SPLIT
Combine multiple PDFs into one. Pull out individual pages or page ranges. Reorder, rotate, and crop pages exactly how you need them.
COMPRESS WITHOUT COMPROMISE
Shrink file sizes for email and uploads while keeping your documents sharp. Choose your compression level and let the app handle the rest.
SIGN & PROTECT
Draw or upload your signature, place it on any PDF, and send. Lock files with passwords, add watermarks, or redact sensitive content before sharing.
SCAN TO PDF
Point your camera at any document, receipt, or whiteboard. The built-in scanner straightens, enhances, and saves it as a searchable PDF with OCR.
AI-POWERED TOOLS
Ask questions about any PDF and get instant answers. Summarize long reports in seconds. Extract tables and key data points automatically. Translate entire documents without leaving the app.
WHO IT'S FOR
Students managing assignments, professionals handling contracts, small business owners processing invoices — anyone who touches PDFs regularly and wants one app that does it all.
HOW IT WORKS
1. Open or import a PDF from Files, email, or your camera
2. Pick a tool — convert, merge, compress, sign, scan, or ask AI
3. Done. Save, share, or export in the format you need.
Your documents stay on your device unless you choose to share them.
