Pixelcheck by Journey Further

About

Pixelcheck is a Chrome extension built by Journey Further for SEO analysts, web developers, and designers. It provides three powerful tools for auditing and inspecting web pages:

IMAGE AUDIT
Scan all images on any page with one click. Each image gets a colour-coded overlay (red/amber/green) showing how oversized it is relative to its displayed size. The audit detects:
- File size and format (with next-gen format flagging for WebP/AVIF)
- Alt text presence and quality
- Priority loading signals (preload, fetchpriority, eager loading)
- Lazy loading detection
- File size detection that works even on CDN-hosted images

Export a full CSV report with all image data, or export just missing alt text URLs for quick fixes.

IMAGE INSPECTOR
Right-click any image and select "Pixelcheck - Inspect image" to see:
- Natural vs displayed dimensions
- File size and format
- Alt text
- Image URL with one-click copy

COLOUR PICKER & BRAND TOOLS
- Use the native eyedropper to sample any pixel on screen
- Scan the entire page to detect all background, text, and accent colours in use
- View colour history across sessions
- Detect all fonts actively used on the page (categorised as web or system fonts)
