Convert Images & Receipts to PDF Directly on Mobile Browsers

Avoid installing bloated native mobile apps that track your location and demand subscription fees. Learn how to convert camera snapshots, handwritten homework, and expense receipts into clean PDFs right in mobile Safari or Chrome.

Why Mobile Web Is Superior to Native Scanner Apps

App stores are flooded with document scanner apps that require mandatory account logins, prompt for weekly $4.99 subscriptions, and upload camera photos to distant cloud analytics endpoints.

By leveraging modern mobile WebAssembly and HTML5 Canvas APIs, SlowPDF runs directly inside iOS Safari or Android Chrome. You take a photo, tap convert, and receive an optimized PDF file in seconds with zero data leaving your smartphone.

3 Simple Steps on Mobile

  2. Choose Photos from Camera Roll: Select JPG, PNG, or HEIC camera snapshots of receipts, slides, or documents.
  3. Adjust Page Margin & Export: Choose A4 or US Letter page dimensions and tap Generate PDF.
