How to Compress an Image to 20KB

Getting a photo down to 20KB requires both resizing and compression. Our tool handles both automatically — just upload your image and it adjusts dimensions and quality to hit exactly 20KB. For best results:

  • Start with a well-lit, clear photo — compression works better on clean images.
  • Optimal dimensions for 20KB are around 200x250 pixels for passport-style photos.
  • The output is JPG, which gives the best quality-to-size ratio at small file sizes.
