Compressing Scanned Pages for iPhone Photos

Updated March 11, 2026 · 9 min read

Scanned pages are often saved at very high resolution. Modern phone cameras produce large files that are more than most sharing and upload needs require.

Recommended settings for iPhone photos

Widthabout 2048 px on the long edge
Quality78
File size500 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Compressing Scanned Pages

A page scanned at 600 DPI can be over 5000 pixels tall. For reading on screen, around 2048 pixels wide is enough.

Text on a white page compresses efficiently, so a target of 500 KB is usually achievable while staying sharp for iPhone photos.

Step by step with TheCompressJPEG

  1. Open the compress JPEG to 500 KB tool, or the main compressor for custom settings.
  2. Drop in your image. Nothing is uploaded; it is processed in your browser.
  3. Set the maximum width to 2048 and the target size to 500 KB.
  4. Press Compress, check the result and download it.

Quick tips

  • Use WebP where it is supported and you control the page.
  • Never re-compress an already compressed JPEG if you can avoid it.
  • Strip metadata from images you share publicly.
  • Always keep the original file and compress a copy.

Quality around 78 keeps photos looking natural while cutting file size substantially.

Will compressing reduce image quality for e-learning courses?

Wrapping up
