How does the image compression tool work?

Our image compression tool uses advanced algorithms to reduce PNG and JPG file sizes by up to 80% while preserving image quality and transparency. All processing happens in your browser - no files are uploaded to our servers, ensuring complete privacy.

What image formats are supported?

We support PNG (with transparency), JPG, and JPEG formats. The tool automatically detects the format and applies the best compression algorithm.

Is my data safe when using this tool?

Yes, absolutely safe. All image processing is done entirely in your web browser using JavaScript. Your images never leave your device and are not uploaded to any server.

Is there a file size limit?

Since processing happens in your browser, the limit depends on your device's memory. Most modern devices can handle images up to 50MB without issues.
