Scanned Document vs Phone Photo of a Document
A flatbed scan at 300 DPI in colour can be 2-5MB for a single page, containing unnecessary colour data. Converting to greyscale cuts size drastically without loss of legibility. For phone photos, straighten and crop page edges first before compressing to 100KB.
How to Resize a Document Image to 100KB

- Switch to greyscale: For text documents, this instantly halves file size.
- Set 100KB target: Process directly in your browser.
- Read the smallest line at 100% zoom: Verify that dates, names, and numbers remain crisp.
