What fits in 5 MB

Spread across the pages, 5 MB gives each page this much room. Text costs very little; scans and photos cost the most.

5 pages1 MBPhotos and scans stay sharp

Rough guide. Text-only pages are often just a few KB each; a scanned page is mostly image data.

What 5 MB is typically for

  • Attaching big PDFs to an email comfortably
  • Brochures and slide decks exported to PDF
  • Upload forms with a 5 MB cap

Limits vary by site and change over time; check the exact number where you're uploading.
