How to Get Under 50KB

50KB requires both smaller dimensions AND compression.

  1. 1.
    Resize dimensions first (if needed). For large photos (smartphone shots at 4000px+), go to the Resize tool and reduce to 400–600px wide first. This alone cuts file size by 80–90%.
  2. 2.
    Compress. Upload your image above and click Compress. The quality is pre-configured for 50KB targets.
  3. 3.
    Verify and download. The compressed file size is shown after processing. Download when under 50KB.
