Free image optimizer tool guide. Learn how to reduce image file sizes while maintaining visual quality for faster website loading and better SEO.
Images are the biggest contributor to page weight on most websites. A single unoptimised photo can be 5MB, while the same image optimised might be 200KB - a 25x reduction. Every kilobyte you save means faster loading times, especially on mobile networks.
Our Image Optimizer compresses your images without visible quality loss.
How Image Optimization Works
- Remove metadata - Strips EXIF data, camera info, GPS coordinates, and thumbnails
- Smart compression - Applies lossless or lossy compression based on the image content
- Colour optimisation - Reduces colour palette where appropriate without visible difference
- Resizing - Ensures images aren't larger than needed for their display size
Best Practices
For photographs, save as JPG with 80-85% quality. For screenshots and graphics with text, use PNG or WebP. Modern format WebP typically provides 25-35% better compression than PNG or JPG at the same quality level.
Run all images through the optimizer before uploading to your website. The improvement in page speed scores (Core Web Vitals) is immediate.
