Visually lossless optimizations

Optimage uses advanced metrics to automatically adjust image quality for up to 10x smaller image files that are visually perceived as originals.

Nearly optimal compression

Max compression ratio is achieved by exhaustively trying various compression parameters and image data structures using novel and traditional heuristics.

Why use Optimage?

Make your website load faster

When building a website, it is important to make all image assets, photographs and other media as small as possible. Recent studies show that most of mobile users abandon sites that take longer than 3 seconds to load.

Make your app smaller for your users

Image assets in your app are probably bigger than needed. Reduce their size, so that your app is faster to download and install.

Efficient sharing

Optimize your images for faster sharing on social networks and other popular services, while reducing the load on them and saving Internet bandwidth.

Reduce file attachments

There is often a strict file size limit on file attachments in emails and web forms. Reduce your images to meet the requirements or send more.
