About Image Optimization
Image optimization is crucial for website performance. Our tool lets you choose between two powerful paths: compressing images in their original format (like JPG and PNG) or converting them to the next-generation WebP format.
WebP typically yields 25-35% smaller file sizes than comparable JPEGs or PNGs, making it ideal for the web. However, retaining the Original Format is often necessary for compatibility with certain legacy systems or specific use cases.
Tips for Best Results
- For most web use cases, select the "Convert to WebP" option for maximum savings.
- A quality setting of 75-85% usually provides the optimal balance between file size reduction and visual fidelity.
- WebP format is ideal for web use, but if you need compatibility with older software, stick with JPEG or PNG formats.
- For transparent images, WebP supports alpha transparency similar to PNG but with better compression.
