Frequently Asked Questions (FAQ)

Are my uploaded images secure?

Yes, absolutely! This tool runs entirely using your browser's JavaScript. Your photos are processed locally on your device and are never uploaded, stored, or sent to any external server.

Which image format provides the best compression?

We highly recommend selecting WebP format. It provides superior lossless and lossy compression for images on the web, often making files 25-34% smaller than comparable JPEG images.

Why did my PNG file size increase?

Native browser compression works best on lossy formats like JPG and WebP. Compressing a PNG file with transparent backgrounds might sometimes result in a larger file depending on the browser engine. To fix this, change the output format to WebP.

Is this tool free to use on mobile devices?

Yes. The tool is 100% free and fully responsive, meaning it works flawlessly across all Android, iOS, tablets, and Desktop devices without any screen overflow issues.
