What Is Image Compression?
Image compression reduces the file size of images by removing redundant data or reducing image quality in ways that are minimally perceptible to the human eye. Compressed images load faster, consume less bandwidth, and improve web performance metrics like Largest Contentful Paint (LCP) and overall Core Web Vitals scores.
Types of Image Compression
- Lossy Compression: Permanently removes some image data to achieve smaller files. JPEG and WebP use lossy compression. At moderate quality levels (70-85%), the visual difference is negligible while file size reductions can reach 60-80%.
- Lossless Compression: Reduces file size without any data loss. PNG uses lossless compression. File size reductions are typically 10-30% but the image quality is perfectly preserved.
Image Format Comparison
| Format | Compression | Transparency | Best For |
|---|---|---|---|
| JPEG | Lossy | No | Photographs, complex images with gradients |
| PNG | Lossless | Yes | Logos, icons, screenshots, images needing transparency |
| WebP | Both | Yes | Modern web use — 25-35% smaller than JPEG at equivalent quality |
| AVIF | Both | Yes | Next-gen format — even smaller than WebP, growing browser support |

Frequently Asked Questions
What quality setting should I use?
For web images, a quality setting of 75-85% provides an excellent balance between file size and visual quality. Below 60%, compression artifacts become noticeable. Above 90%, file size savings diminish significantly.
Will compression affect my image dimensions?
No. Compression reduces file size without changing the image's width or height. To change dimensions, use an image resizer tool instead.
