Lossy, Glossy or Lossless – which one is the best for me?

• Lossy is the best option for most users. The images processed with Lossy algorithms are the smallest optimized images you can get. So, if the speed of your site is paramount and you want the best balance between optimization and picture quality, we recommend you to continue to use Lossy optimization.

  Glossy is the best choice if you still care about Google PageSpeed Insights or GTmetrix but you believe that a slight loss of page speed is an acceptable compromise for a top notch image quality.

  Lossless optimized images are pixel-by-pixel identical with the originals, but they offer a smaller size reduction compared to either Lossy or Glossy processed files. If you want your image information to remain untouched, while slightly reducing image size, then select this option.

Does a credit equal an optimized image?

• If you are using ShortPixel Image Optimizer, yes, that is correct. If you are using ShortPixel Adaptive Images, a credit equals 5 MB of CDN traffic.

What types of formats can be optimized?

• ShortPixel optimizes JPEG, PNG, GIF and PDF type files. We also offer the option to also generate the WebP/AVIF version of the image.

Do you optimize the images in cloud?

• Yes, all the images processed by ShortPixel are optimized in the Cloud. This takes the load off of your server and allows us to produce the best results.

What payment methods are accepted?

• We accept payments via PayPal and credit card.

How do I activate the API key on a WordPress multisite?

• You have to activate the plugin as the network admin and then activate it manually on each individual site in the multisite. Once you have done that, the Settings menu appears and you can add the API key for each individual site. As an alternative, you can edit wp-config.php and add this line

  define('SHORTPIXEL_API_KEY', 'APIKEY');

  where ‘APIKEY’ is the API Key received upon sign up. If configured that way, the API key will be used for all the sites of the multisite but will only be visible on the main site’s Settings page, being hidden for the rest of the sites.

Do you optimize existing WebP/AVIF images?

• No, but ShortPixel can generate the optimized WebP/AVIF version of any JPG, PNG or GIF image that you're optimizing. If your images are delivered using JavaScript, then it is possible that our way to serve the WebP/AVIF versions of your images to the compatible browsers will not work.

How do monthly subscriptions work?

• After signing up, you can upgrade to any of our available monthly plans. They give you access to larger image quotas that renew automatically each month. After purchasing a monthly subscription, the billing happens automatically each month until you decide to cancel your payments. No headaches. :)
