How to Use the Image Compressor

  1. Choose an image with the file picker.
  2. Set the quality slider:
    • 80–90% – slight size reduction, almost no visible change
    • 60–70% – balanced, recommended for web use

JPG files stay JPG. PNG files are saved as WebP so transparency is preserved. If a file is already well optimized, your original is kept.

How Image Compression Improves SEO

Using modern formats like WebP and compressing images before upload also improves crawl efficiency and image search visibility.
