Frequently Asked Questions

How much can I compress without losing quality?

With our smart compression algorithm, you can typically reduce file sizes by 70-90% while maintaining excellent visual quality. Our tool analyzes each image to find the optimal compression level processed entirely in your browser.

What compression types does your tool offer?

Our WebAssembly image optimizer offers both lossy and lossless compression. Lossy (JPEG, WebP) removes some data for smaller files, while lossless (PNG) maintains perfect quality. Our WebAssembly engine intelligently applies the best method for each format.

Is this image compressor completely free to use?

Yes! This is a completely free online tool with no hidden costs, no watermarks, and no usage limits. No sign up required - just upload your images and start compressing instantly.

How is my privacy protected during image processing?

All image compression happens locally in your browser using WebAssembly technology. Your images never leave your device - no server uploads, no data collection, and complete privacy protection for sensitive visual content.

Which format should I choose for optimal results?

Choose JPEG for photos, PNG for transparency, WebP for modern browsers (25-35% smaller), and AVIF for best compression. Real-time preview shows your compression results instantly as you adjust settings.
