## 🌐 Why Image Optimization Matters for SEO

Images can make up **over 50% of your page’s total weight**.
When properly optimized, they:
– Load faster (reducing bounce rates)
– Improve **Core Web Vitals** (especially LCP and INP)
– Increase organic traffic through Google Image Search
– Enhance accessibility for all users

Faster pages mean better rankings — and happier visitors.

## 🧠 1. Use Descriptive Filenames

Search engines read filenames to understand image context.

Tips:
– Be specific, not spammy.
– Keep it under ~125 characters.
– Use keywords naturally.

## 🏷 2. Write Meaningful Alt Text

**Alt text** is crucial for both SEO and accessibility.
It describes an image’s purpose and helps screen readers — while also giving search engines context.

## 🧩 3. Compress and Resize Before Uploading

Large, uncompressed images slow down pages — hurting SEO.
Use our [**Image Compressor Tool**](/image-compressor) to:
– Resize to appropriate dimensions
– Convert to **WebP** or **AVIF**
– Reduce file size by 70–90% instantly
– Preserve quality while staying privacy-safe

Everything happens **client-side**, so no data is uploaded or tracked.

## ⚙️ 4. Choose the Right Format

Use modern formats for best performance:
– **WebP:** Excellent balance between size and quality
– **AVIF:** Smaller than WebP, ideal for high-resolution content
– **SVG:** For vector graphics, icons, and logos

Fallbacks:
– Keep a JPEG/PNG backup only if necessary for older browsers.
