Advanced JPEG Compressor is a free software program for Windows that allows you to compress JPEG images to reduce their file size without significant visible loss of quality. It offers more control over the compression process than many basic image editing programs, providing options to fine-tune the compression level and balance file size against image quality. This can be useful for saving space on hard drives or for optimizing images for web use, email, or other situations where smaller file sizes are beneficial.

While it[SQ]s labeled "advanced," the user interface is generally straightforward and easy to navigate, even for users without extensive photo editing experience. Its primary function is compression; it doesn[SQ]t offer extensive image editing features like resizing, cropping, or color correction.
