What is Image Compression?
Image compression is the process of reducing the file size of an image while maintaining acceptable visual quality. This is essential for websites, email attachments, social media, and storage optimization. Our free online image compressor uses advanced algorithms to significantly reduce file sizes without noticeable quality loss.
There are two main types of image compression: lossy compression and lossless compression. Lossy compression (like JPEG) removes some image data to achieve smaller file sizes, while lossless compression (like PNG) preserves all original data but typically results in larger files. Our tool supports both methods, giving you full control over the compression level.
