Compress an image to a target size (20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, 2 MB)

Many forms, job portals and exam sites ask for a picture under a certain size, such as 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB or 2 MB. To reduce image size in KB:

  1. Compress the image and check the result in your file manager.
  2. If it is still too big, shrink the dimensions with Resize Images, then compress again. Smaller pictures mean smaller files.
  3. If the file is a PNG, try PNG to JPG, because JPG is usually smaller for photos.

The tool reduces file size, but it does not promise to hit an exact number, so always check the final size before you upload.

Compress images for websites

Large pictures slow pages down. Before you upload photos to a blog or online store:

  • Resize first to the largest size you will actually display.
  • Compress next to cut the file size.
  • Consider WebP for the web. Convert Images can switch formats.

This helps with compress images for web and compress images for website goals.

Tips for the best quality

  • Do not compress more than needed. Heavy compression can blur details or add blockiness.
  • Keep your original. Work on a copy so you can always go back.
  • Choose the right format. JPG suits photos, while PNG suits screenshots, logos and graphics with sharp edges.
  • Avoid compressing the same file again and again. Each round can lose more quality.
