How to Optimize Images for Faster Website Loading

> Faster images = faster websites. In this guide, you’ll learn how to optimize your images using our free online tools and boost your website’s speed, SEO, and user experience.

## 1. Use Modern Image Formats
Newer formats like **WebP** and **AVIF** achieve the same visual quality at a much smaller file size.
Both are supported in all modern browsers.

| Format | Best For | Notes |
|———|———–|——-|
| AVIF | Photos & graphics | Best compression ratio, excellent quality |
| WebP | All-round use | Widely supported, efficient balance |
| JPEG | Legacy support | Still useful where older browsers matter |
| PNG | Transparent & line art | Use only when you need lossless |
| SVG | Icons & logos | Lightweight and scalable |

👉 Convert your existing images easily with our [**Image Compressor Tool**](/image-compressor).

## 2. Resize Before Uploading
Upload images that are **only as large as you need them**.
If your website displays an image at 800 px width, avoid uploading a 4000 px file.

Our [**Image Compressor**](/image-compressor) automatically resizes large images before compression — no design software needed.

## 3. Compress Without Losing Quality
Compression reduces file size while maintaining visual clarity.

Recommended settings:
– **WebP:** Quality 75–80
– **AVIF:** Quality 40–55
– **JPEG:** Quality 70–80 with progressive encoding

Try compressing with our [**Image Compressor Tool**](/image-compressor) — it runs locally in your browser, ensuring privacy and instant results.
