Image Compression Analyzer
Analyze all images on a page for format optimization, detect oversized images, and estimate how much bandwidth you can save with compression.
How to Use the Image Compression Analyzer
The Image Compression Analyzer reviews every image on a page for format choice, oversized dimensions, and the bandwidth compression could save. Freight-heavy pages carrying full-resolution photos are often the slowest pages on a logistics site, and the fix rarely requires a redesign.
Formats, dimensions, and where the weight hides
The report groups findings by cause. Photos saved as PNG instead of WebP or AVIF carry far more bytes than the format requires. Images delivered at twice their displayed dimensions waste bandwidth on every visit, a common problem when a 400-pixel thumbnail ships at 1600. Oversized hero images dominate the total. Address the largest files first; the savings are proportional, so the top three offenders usually account for most of the page weight.
Compression without visible quality loss
Modern formats maintain visual quality at a fraction of the file size, and most visitors cannot tell the difference at screen resolutions. Convert the heaviest photos, set explicit width and height attributes to prevent layout shifts, and serve responsive sizes through your CDN. After deploying, re-run the analyzer to confirm the reported savings match the estimate, then check the page speed analyzer to see the effect on Core Web Vitals.

Frequently Asked Questions
What's the best image format?▼
WebP offers the best compression-quality ratio. AVIF is newer and even better but less supported. JPEG XL is emerging.
How much can I save?▼
Switching from JPEG/PNG to WebP typically saves 25-35% without quality loss.
How accurate are the results?▼
Our tools use multiple AI engines and real-time data sources to provide accurate, up-to-date analysis.
Can I use the results commercially?▼
Yes, all results are yours to use for any purpose.
How much page weight is reasonable for a landing page?▼
Under two megabytes is a workable target for image-heavy pages, and less for text pages. The analyzer ranks images by size, so the goal is shrinking the top of that list rather than hitting one universal number.
Will compression change how my images look?▼
Converting photos to modern formats at standard quality settings is visually transparent on screens. Keep original files in your asset library if you print from them, and serve the compressed versions to visitors.
