## What is One Tool Box?

One Tool Box brings together the everyday utilities you'd otherwise need a dozen separate apps for — documents, PDFs, photos, audio, and more — in one fast, focused app that never leaves your device.

DOCUMENTS & PDF
- Scan documents with auto-straightening and clean output
- Sign PDFs by hand, place and flatten your signature
- Merge, organize, reorder, and page-number PDFs
- Compress PDFs while keeping text sharp
- Password-protect PDFs and add watermarks
- Convert PDFs to images and images to PDF
- Copy IDs and passports to a print-ready sheet

PHOTOS & IMAGES
- Retouch: heal blemishes, censor, adjust, apply filters and crop
- Remove backgrounds automatically
- Compress and convert between image formats
- Add watermarks, stitch panoramas, compare images side by side
- Crop to circles, split into grids, read EXIF data
- Pick colors from any photo
- Passport and ID photos sized to spec

AUDIO & FILES
- Transcribe recordings to text, fully on-device
- Convert audio and video between common formats
- Encrypt and decrypt files and folders, interoperable with your computer
- A private vault for sensitive documents
- OCR: pull text out of scanned pages and images
- Translate text between languages
- Word count and text utilities

FOR LIFE IN FRANCE
- Income tax and mileage allowance calculators
- VAT calculator
- IBAN checker
- Administrative letters and attestations, ready to send
- Notaire and calendar helpers

Everything happens locally on your device: no accounts, no ads, no analytics, no data collection of any kind. One Tool Box contains no networking code whatsoever, so nothing you scan, sign, encrypt, or transcribe can ever leave your device.

One purchase. Every tool. Nothing else needed.
