How does image compression work?

Our Image Compressor uses advanced algorithms to reduce file size by removing unnecessary metadata and optimizing pixel data. We offer both lossy compression (smaller files, slight quality reduction) and lossless compression (no quality loss, moderate size reduction).

What image formats are supported?

The Image Compressor supports JPG, PNG, WebP, and GIF formats. JPG is best for photographs, PNG for graphics with transparency, WebP for modern websites, and GIF for simple animations.

Are my images stored on your servers?

No. All compression happens 100% in your browser. Your images never leave your device — we don't upload, store, or process them on any server. This ensures complete privacy and security.
