Image compressor

Compress an image below 500 KB

Useful for

  • Portfolio images that need a file-size cap without aggressive compression.
  • Presentation graphics that should stay detailed but easy to share.
  • Product photography for upload forms with larger limits.

Limitations

  • The output is always JPG in this compression workflow.
  • Transparent areas become white because JPEG does not support alpha transparency.
  • The tool compresses file size only and does not provide custom resize presets.

Questions

Frequently asked questions
