Imagify is an image compression service created by the folks behind the popular WP Rocket caching plugin for WordPress. Although it’s geared towards WordPress users (with the Imagify plugin), it can be used through the web interface or integrated with any content management system via their API.

Plans & Pricing

Imagify has a free tier, offering compression for up to 25mb of images each month. Any decent-sized website will exhaust that limit very quickly, so a paid plan will almost certainly be necessary. The starter plan offered will handle 1GB of images—roughly 10,000 photos—each month for $4.99. You can also buy one-time plans starting from $10.

Something we found frustrating was that it’s impossible to cancel an active Imagify subscription through the Imagify website. The only way to prevent automatic renewal is to contact Imagify’s customer support. This seems intentionally designed to make cancellation difficult to keep customers paying for something beyond the time they wish to use the service. Similarly, the website offers no way to delete a saved credit card—something which almost certainly violates PCI compliance standards or maybe even the GDPR laws.

In all honestly, the monthly subscription model doesn’t really work for a service like Imagify. Lots of sites don’t replace images very often, so a complete optimization once every couple of years would be sufficient. Utilizing Imagify’s one-time plans are a much better idea (albeit slightly more expensive) than signing up for a subscription.

Compressing Images

Imagify has different compression levels available, so you can choose how intensely your images are compressed. There’s the lossless (meaning images don’t lose any quality) normal option, and the lossy aggressive option.

We found that the aggressive compression reduced the image quality to the point that photos became unpleasantly blurry, so we stuck with the normal option. Fortunately, Imagify keeps a backup of all images prior to compressing them, so it’s easy to switch to a different compression level if you’re unhappy with the results.

An especially handy feature of the Imagify WordPress plugin is that you can designate non-media folders (such as plugins or themes) for optimization. It’s an easy way to shave a few milliseconds off your websites’s load time.

The Results

We optimized about 11,000 images in total. The Imagify plugin helpfully calculates the average savings from all images that were optimized, which in our case was 17%. That didn’t lead to any noticeable increase in page loading speeds, however users on slower connections may feel differently.

Closing Thoughts

Imagify did exactly what it claimed at a reasonable price.

There’s an argument that compressing images to improve page speed is a lot of effort for very little reward, but if you’ve already got caching, script optimization, and content delivery under control, shaving a few extra milliseconds off with Imagify can’t hurt.
