How to Use

  1. Upload an image using the file picker or drag and drop.
  2. Enter your target file size in KB (e.g., 100 KB).
  3. Choose output format: JPEG or WebP recommended for best compression.
  4. Click Compress to process the image.
  5. Check the resulting file size and click download if satisfied.

How It Works

Image compression uses binary search on the quality parameter (0.01 to 1.0). The image is repeatedly encoded at different quality levels until one produces output closest to the target size. JPEG and WebP support quality control; PNG does not.
