Frequently Asked Questions & Optimization Tips

Why is Image Compression Important for SEO?

Search engines like Google prioritize fast-loading websites. Large images are the #1 cause of slow page speeds. By compressing your images or converting them to modern formats like WebP, you significantly reduce load times, improve user experience, and boost your Core Web Vitals scores—leading to better search rankings.

Why Convert Videos to WebM?

WebM is a royalty-free video format designed specifically for the web by Google. It offers high-quality video at much smaller file sizes compared to MP4. Using WebM videos ensures your pages load faster on mobile devices, reducing bounce rates and improving your technical SEO performance.

Is it Safe to Process Files Here?

Yes, 100% safe. Unlike other online tools, this processor runs entirely in your browser using JavaScript and HTML5 canvas. Your photos and videos are never uploaded to any external server. They stay on your device, ensuring complete privacy and security for your sensitive data.

Can I resize images without losing quality?

Yes! Our "Smart Resize" algorithm maintains high fidelity even when downscaling. For the best balance, we recommend converting to WebP with the default 85% quality setting, which is indistinguishable from the original but rarely 50-80% smaller in file size.

Does this work on Mobile?

Absolutely. The tool is fully responsive and uses your phone's processor. However, for batch processing hundreds of files, we recommend using a desktop for better performance and battery life.
