Image compression is the process of reducing the file size of an image by removing redundant data while maintaining acceptable visual quality. This can be achieved through lossy or lossless methods, making the images more efficient for storage and faster to transmit, especially for web use.

Compressing images is essential for optimizing web performance, as smaller files load faster, improving user experience and SEO. It also saves storage space and bandwidth, making it easier to share images via email or store them on devices and cloud services.

Yes, compressing images is generally safe, especially when using reliable tools. Lossless compression preserves all data, while lossy compression reduces file size with minimal quality loss. Always keep a backup of the original image for safety.

The compressor supports popular formats like JPEG, PNG, and GIF, commonly used on the web. These formats are ideal for various applications, ensuring that users can efficiently reduce file sizes while maintaining necessary quality.
