What is Image Optimization?
Image optimization reduces file size without significantly degrading visual quality. Smaller images load faster, use less bandwidth, and improve Core Web Vitals (LCP). Key techniques include choosing the right format, adjusting compression levels, resizing dimensions, and stripping metadata.
This analyzer helps you identify optimization opportunities by analyzing your image's characteristics:
- Format comparison — JPEG vs PNG vs GIF vs WebP vs AVIF
- Bit density analysis — How efficiently pixels are encoded
- Dimension analysis — Whether the image is larger than needed for web
- Estimated savings — Potential file size reduction for each technique
Frequently Asked Questions
Which image format is best for the web?
WebP offers the best balance of compression and browser support (97%+). AVIF provides even better compression but is only supported in newer browsers. Use JPEG for photos if compatibility is critical.
Is my image data uploaded to a server?
No. All analysis happens entirely in your browser using JavaScript. Your image never leaves your device.
What is bit density and why does it matter?
Bit density measures how many bits are used per pixel. High bit density (over 8 bpp) often indicates unnecessary detail or metadata that can be compressed. Lower values suggest more efficient encoding.
