General Information

Authorizing to Buildify

Before starting to work with the extension you need to enter the authorization keys by going to Stores → Configuration → Aheadworks Extensions → Minifier. Two keys are required: Public and Private API.

You can find Public and Private API keys in My Projects and Licenses in personal account on aheadworks.com.

Enable prefetching

To enable prefetching in Minifier, set Enable to Yes. By default, this option is set to No. Minifier will track when a user is about to click on a link on your shop and load that link in the background.

Minifier on Backend

The dashboard has four areas:

Images optimized
Image weight reduce by
Average product load time decreased by
File names optimized

How does your website perform on various networks?

To find out how does your website performs on different networks, click on the question mark. In the table down below you will see information on how your average product page, as well as the entire store, would perform on two most commonly used networks - 4G and household WiFi.

Clicking on the Review us button you will be automatically redirected to the Minifier product page on Shopify app store.

Settings Configuration

The Automatic optimization service tab provides information about the number of already optimized images. For changing optimization configurations click on Edit setting.

Automatic optimization process goes via the Kraken. Where customers’ images are processed in order and loaded back in the amount of 250 images at a time.

The settings area allows to configure the following:

lossy or lossless kind of compression - lossy compression will reduce the image size by up to 70%, losing a little in quality; lossless compression will reduce the image size by up to 30%
optimize only published products - Minifier will skip images that don't need to be optimized, which will speed up the optimization process
convert files to JPG - images saved in JPG load faster than in PNG
skip previously optimized images - previously compressed images will not be compressed
optimize file names automatically - for higher search engine rankings, filenames must be supplied by keywords. If this configuration is switched on, Minifier will combine image titles from the file data such as PRODUCT TYPE and PRODUCT TITLE. When PRODUCT TYPE is unavailable, the image title will be made from PRODUCT TITLE only.

After clicking on the Save settings button new settings will be saved and will be used in the future for the auto-optimization process for not optimized store pictures.

Optimization performance

The images optimized graph introduces the information on the extension usage. Choose the needed period to check the number of optimized images during it.

The Optimization History area contains the following columns:

Type – the name of the report
Status – the condition of an optimization process:
- collecting;
- collected;
