Frequently Asked Questions

Is my image data stored on your servers?

No. This tool operates entirely within your web browser using the Canvas API and WebAssembly. Your images never leave your local environment, ensuring maximum privacy for sensitive assets.

What is the difference between lossy and lossless conversion?

Lossy formats (like JPEG and WebP) discard some data to achieve significantly smaller file sizes. Lossless formats (like PNG) retain every single pixel exactly as it was, which is ideal for graphics needing transparency or high precision, though file sizes are larger.

Why should I use WebP?

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. It is roughly 25-34% smaller than comparable JPEG or PNG files, leading to faster page load times and better SEO rankings.
