💡 WHY DOCUSIZE

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Many PDF and scanner apps upload your files, require sign-up, or hide basic features behind a paywall. DocuSize is different: a complete scanner, resizer, and PDF toolkit in one app, 100% offline.

Use DocuSize to:

• Scan documents and save as PDF

• Resize a photo to an exact KB size

• Compress a PDF to fit an upload limit

• Combine multiple PDFs into one file

• Convert images to PDF

• Print 2 or 4 pages on one sheet (N-up)

PERMISSIONS

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Camera — used only when you open the scanner

• Storage / Photos — used to read your source files and save the documents you create
