What is image compression and why does it matter?
Image compression reduces the file size of an image by removing redundant or less-important data. For websites, compressed images mean faster page load speeds, better Core Web Vitals scores, and lower bandwidth costs — all of which directly improve SEO rankings and user experience.
There are two types of compression:
- Lossless compression (PNG, GIF) — reduces file size without any quality loss by removing metadata and redundant colour information.
- Lossy compression (JPG, WebP) — achieves much higher reduction ratios by selectively discarding image data that the human eye barely notices.
Our tool applies the right algorithm automatically based on your image format, so you get the best result every time.
How much can you reduce image file size?
Typical compression results vary by format and image content:
- PNG files: 30–70% reduction using lossless optimisation
- JPG files: 40–80% reduction at quality 80 (the default sweet spot)
- WebP files: 25–60% reduction — WebP is already very efficient
For most web images, setting JPG quality to 75–85% produces files that are visually identical to the original but 50–70% smaller — the same technique used by Google, Facebook, and every major CDN.
