Question 1

How does browser-based image compression work?

Accepted Answer

We use WebAssembly and the HTML5 Canvas API to decode your image, resize it if necessary, and re-encode it at a lower quality setting directly in your browser's memory.

Question 2

Are my images uploaded to a server?

Accepted Answer

No. Your images never leave your device. The compression happens 100% locally in your browser, ensuring complete privacy for sensitive personal or business photos.

Question 3

What is the maximum file size I can compress?

Accepted Answer

While there is no hard limit from our side, extremely large images (over 50MB) may crash your browser tab due to memory constraints inherent to client-side processing. For best results, use files under 30MB.
