Why compress images?

Fit upload limits

Forms, job portals and government sites often cap uploads at 100 KB, 500 KB or 1 MB. Set a target size and the compressor gets your image under it.

Faster websites

Images are usually the heaviest part of a web page. Smaller files load faster and help Core Web Vitals and SEO.

Easier sharing

Smaller photos send faster by email and messenger and use less storage.

Tips

  • Start with "Recommended"

    It removes most of the file size while keeping photos looking the same. Use Strong or Maximum when size matters more than fine detail.

  • Need an exact size?

    Enter a target size such as 100 KB or 200 KB. For big reductions, resizing the image first helps keep it sharp.

  • Switch format for extra savings

    Saving as WebP or AVIF often halves the size again compared with JPG.

Common uses

  • Getting a photo under 100 KB or 1 MB for a form
  • Speeding up website images
  • Emailing many photos
  • Saving phone and cloud storage
