Frequently Asked Questions
How accurate are the compression metrics?
Our analysis uses professional-grade algorithms to provide precise compression ratios, quality scores, and performance metrics. For example, WebP typically shows 25-35% size reduction vs JPEG at equivalent quality, while AVIF achieves 40-50% savings - results verified against industry tools.
What makes this comparison tool different?
Unlike basic converters, we provide detailed performance analytics, visual quality assessment, and optimization strategies. For instance, our synchronized pixel-level inspection helps identify JPEG blocking artifacts vs WebP's smoother gradients, enabling data-driven format decisions.
Can I analyze specific image types?
Yes! Our tool adapts analysis based on image characteristics. For example: product photos benefit from AVIF's superior compression, logos/graphics work best with PNG transparency, while screenshots optimize well with WebP lossless mode.
Do you provide optimization recommendations?
Absolutely! Based on your image content and selected quality levels, we suggest optimal formats and settings. For instance, if your photo shows minimal quality loss at WebP 80% vs JPEG 90% with 40% size savings, we'll recommend WebP for web deployment.
Is this tool really free to use?
Yes! Our tool is completely free with no hidden costs, registration requirements, or usage limits. All processing happens in your browser using WebAssembly, so there are no server costs to pass on to users.
