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, install and use.

Compress PDF documents

Reduce your scanned PDF documents down to 150dpi for sharing on the Web.

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 hidden metadata collection, upload faster and preserve image quality.

Reduce file attachments

Reduce file size of your images and documents to meet the strict requirements 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.
