Frequently Asked Questions (FAQ)
Q: Why convert images to WebP?
A: WebP is Google's modern image format designed specifically for the web. Compared to JPEG and PNG, WebP files are typically 25–35% smaller at the same visual quality. Smaller images mean faster page load times, lower bandwidth costs, and better Core Web Vitals scores, which directly improve your site's SEO ranking.
Q: Is my image data private and secure?
A: Yes, absolutely. All processing is done locally in your browser using JavaScript and Canvas. Your images are never uploaded to any backend server, ensuring 100% data privacy.
Q: Does this tool support transparent backgrounds?
A: Yes, when converting to PNG or WebP, the tool preserves transparency. If you choose JPEG, transparent areas will automatically receive a white background because the JPEG format does not support transparency.
