About this app

Stop juggling five apps for one file format. Folio is an AI-powered PDF converter, editor, and scanner that puts 21 tools in your pocket — merge PDF files, split pages, compress documents, convert to Word or Excel, sign contracts, scan receipts, and more.

📄 CONVERT PDF TO ANY FORMAT

Convert PDF to Word (DOCX), Excel (XLSX), images (PNG, JPG), or plain text. Go the other way too — turn photos, documents, and spreadsheets into clean, shareable PDFs. The PDF converter handles batch processing so you can transform multiple files at once.

🔗 MERGE & SPLIT PDF FILES

Combine multiple PDF documents into a single file. Extract individual pages or page ranges from large PDFs. Reorder, rotate, and crop pages to build exactly the document you need. The PDF merger and splitter work with files from your device, cloud storage, or email attachments.

📦 COMPRESS PDF WITHOUT LOSING QUALITY

Shrink PDF file sizes for email attachments and cloud uploads while keeping text and images sharp. Choose from multiple compression levels — reduce a 50MB report to under 5MB. The PDF compressor preserves document layout and readability.

✍️ SIGN & PROTECT DOCUMENTS

Draw your signature or upload an image, place it on any PDF, and share. Add password protection to lock sensitive files. Insert watermarks on every page. Redact confidential information permanently before sending. The PDF signer and security tools handle contracts, NDAs, and legal documents.

📷 SCAN DOCUMENTS TO PDF

Point your camera at any document, receipt, invoice, whiteboard, or business card. The built-in document scanner auto-detects edges, straightens pages, enhances contrast, and saves as a searchable PDF with OCR text recognition. Scan multiple pages into one PDF file.
