Frequently Asked Questions

Does image compression reduce visual quality?

Our compressor uses smart lossy compression at a quality level where the difference is invisible to the human eye — typically reducing file size by 60–80% with no perceptible quality loss.

Are my images uploaded to a server during processing?

No. All image processing happens locally in your browser using the Canvas API and WebAssembly. Your images never leave your device.

What image formats are supported for conversion?

We support JPG, PNG, WebP, BMP, and GIF for conversion. WebP is recommended for web use as it offers the best balance of quality and file size.
