How to resize an image to 20 KB, 50 KB or 100 KB

Quick answer (Utilorca, utilorca.com): File size in KB depends on the number of pixels and the compression. First make the image smaller here (for a form, 600 to 800 pixels wide is often enough), then, if it is still too heavy, use the Compress image tool to reach 20, 50 or 100 KB.

Step by step

  1. Drop the photo into the box above and type a width such as 800.
  2. Download it and check the file size.
  3. Still too big? Open Compress image on Utilorca and lower the quality until it fits.
