What is Optimage?

Optimage is a simple yet powerful image optimization tool currently available for Mac that aims for automatic image compression at consistent visual quality and highest density.

Optimage is the first tool to achieve visually lossless compression in a comprehensive set of third-party tests. It is the new state of the art for PNG and JPEG compression with various improvements to GIF, SVG, PDF, WebP, ICO and ICNS compression.

Thousands of people have been successfully using Optimage to optimize their images and documents.

Visually lossless optimization

Optimage uses novel perceptual metrics and improved encoders to reduce image size by up to 90% without losing visual quality.

Clean and simple interface

A simple native interface gives you power to automatically compress images without touching any settings yet achieving the best performance.

Why use Optimage?

Make your website load faster

If you build websites, it is important to make all image assets, photographs and other media as small as possible because most users, especially on mobile, will leave a page that takes longer than three seconds to load.

Reduce app size

Automatically optimize image assets following Apple's HIG guidelines and Google's Android guides to save storage space, reduce mobile data usage and improve your app performance for your users.

Compress PDF documents

Reduce the size of your scanned PDF documents with max resolution 150dpi which is perfect for sharing on the web and via email.

Optimize vector graphics

Minimize bloated SVG or PDF images produced in tools like Illustrator, Photoshop or Sketch for your website or app.

Efficient sharing

Optimize your images for social media like Twitter, Facebook or Slack to prevent personal data collection, upload faster and preserve image quality.

Reduce file attachments

Reduce the size of your images and documents because nobody wants to receive huge files and there are often strict file size limits for email and form attachments.

Protect your privacy

Securely remove any hidden sensitive information from photographs and documents without relying on third-party services that may collect your data.
