Where 150KB shows up

Online job boards, university portals, community profiles and some CMS uploads enforce 150KB. It sits between the mild 200KB and the strict 100KB caps, so most images reach it with a standard 60-70% export.

Get under 150KB

  1. Open the Compress Image tool.
  2. Drop your image.
  3. Set quality to 65% and read the size.
  4. If still above, resize to 1200px first.
  5. Download and upload.

A 1200px image at 65-70% typically lands between 80KB and 150KB with no visible loss on screen.

Always start from the original

Compress from your original photo, not from a previously compressed file — re-encoding compresses artifacts again and makes everything softer at the same file size.
