Compress Image to 100 KB

Reduce your image file size to exactly 100 KB. This is the most common target for email attachments, job applications, CV photos, LinkedIn profile pictures, and general web uploads.

When to use 100 KB compression

  • Job application portals and CV photos
  • LinkedIn and professional profile pictures
  • Email attachments with 100-200 KB limits
  • Web forms and online applications
  • Document scans for digital submission

Tips for best results

  • Start with a reasonably sized image (under 3000px on longest side)
  • Use WebP output for better quality at the same file size
  • If 100 KB is impossible, the tool will suggest resizing
  • Crop unnecessary background before compressing

How it works

  • Your image never leaves your device — all processing happens in your browser
  • Binary search finds the optimal quality setting to match your target size
  • If the target cannot be reached at minimum quality, you'll see the best possible result
  • WebP typically achieves 25-35% smaller files than JPEG at equivalent quality
