Tornado PDF: View,Edit, Reader

Tornado PDF is the calm, fast PDF toolbox built for iPhone and iPad. Merge, sign, compress, convert, scan, and OCR every tool you actually use, in one pocket-friendly app. Stop juggling four different PDF apps. Stop uploading private documents to random websites. Tornado PDF runs every operation on your device, so your contracts, receipts, and IDs never leave your hands. EVERY TOOL YOU NEED • MERGE - Combine unlimited PDFs into one. Drag pages into the order you want. • SPLIT & EXTRACT - Pull out the two pages that matter. Leave the rest behind. • ROTATE & CROP - Real page previews, not placeholders. Straighten sideways scans in seconds. • COMPRESS - Shrink chunky files small enough to email, while keeping the text crisp. • SIGN -Draw a signature with your finger or Apple Pencil. Drop it on the line. Done. • CONVERT -Turn PDFs into Word, Excel, PowerPoint, JPG, PNG, or HTML -and back again. • OCR -Make old photocopies searchable. Scanned text becomes text you can copy and paste. • PASSWORD PROTECT -Lock a document before you send it. • REDACT -Cover sensitive details so they never come back to haunt you. • WATERMARK -Brand a draft, mark a copy "confidential", or stamp every page. • EDIT TEXT -Fix a typo on a contract without printing, scanning, and re-uploading. • FORMS -Fill, save, and sign PDF forms without ever printing them. • SCAN -Use your camera to turn paper into a clean, cropped, OCR-ready PDF. • BATCH -Run the same operation on a folder full of files. Save your evening. WHY PEOPLE SWITCH TO TORNADO PDF • ON-DEVICE PRIVACY -Your files are processed locally. Nothing is uploaded to a server, ever. • NO ACCOUNT REQUIRED -Open the app and start working. No signup, no email harvesting. • FAST -Tools open instantly. Compression and conversion run in the background. • CALM DESIGN -Built for the messy reality of paperwork, not for showing off animations. • iPHONE & iPAD -A real workbench on iPad with split view, drag and drop, and Apple Pencil support. • WORKS OFFLINE -Sign a contract on a plane, merge receipts in a basement, OCR a scan in a tunnel.
