JPEG Imager

Optimize the size and quality of your images.

JPEG Imager is a simple and easy-to-use interactive image compressor, primarily designed to help you find the optimal balance between visual quality and file size of your pictures and digital photos.

It provides various compression controls, a fast real-time preview and handy side-by-side comparison of an image before and after compression. You can fiddle with parameters and observe the effect almost instantly. It is also possible to specify the desired file size or compression ratio and let the program adjust the quality controls automatically.

Despite its name, the program is not limited to JPEG only. It can also compress to PNG and GIF. That allows you to easily compare which of the formats best suited for your pictures.

Additionally, the program offers a set of basic image manipulation and enhancement tools. With it you can resize and rotate an image, crop the edges, adjust brightness, contrast and color balance, enhance saturation and sharpness, put text or caption on a picture, and more. Virtually every tool comes with a real-time preview.

JPEG Imager may prove to be useful if you often work with scanned images or digital camera, or when you prepare your images for the Internet.
