What is the ideal image file size for a website?

Hero images should be under 200KB, product images under 150KB, and thumbnail images under 50KB. These targets keep page load times under 3 seconds on average connections.

What image format is best for web use?

WebP is the best choice for modern browsers, offering 25–34% smaller files than JPEG. JPEG is the most universally compatible. PNG is best for images with transparency or logos.

How much can I compress an image without visible quality loss?

JPEG quality of 75–85% is typically indistinguishable from the original on screens. Below 60%, compression artifacts become noticeable in photographs.

Does compressing images help SEO?

Yes. Google uses page speed as a ranking factor, and large images are one of the most common causes of slow load times. Compressed images directly improve Core Web Vitals scores.

Can I use FixTools to optimize images for WordPress?

Yes. Compress images to under 150–200KB using FixTools, then upload directly to WordPress. This is faster and avoids the overhead of WordPress image optimization plugins.

How does browser-based compression work?

FixTools uses the browser's built-in Canvas API to re-encode images at lower quality levels. No files are sent to a server — everything runs locally on your device.
