# Image SEO Optimizer

> Check an image's SEO readiness — filename, alt text, format, and file size — against best practices.

**Category:** Performance

## How it works

The Image SEO Optimizer runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full performance audit.

1. Enter the relevant input for your page or project.
2. Review the tool's output and the reasoning behind each recommendation.
3. Apply the changes it surfaces to your actual page or content.
4. Re-check after publishing to confirm the fix took effect.

**Why it matters:** Core Web Vitals are a confirmed Google ranking factor and a direct driver of conversion rate — slow pages lose both rankings and revenue, and most performance problems are fixable once you know exactly what's slow and why.

This is a free, interactive, browser-based tool — no signup required. It runs client-side JavaScript, so this Markdown page describes what it does; [use the live tool](https://iliassami.com/tools/image-seo-optimizer) to actually run it.
