Frequently Asked Questions
Common questions about ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF
ShortPixel consistently has better compression rates along with more features, backup support and has very affordable one-time or monthly plans. Here are a couple of independent reviews: AuthorityHacker - "ShortPixel is our tool of choice, simply because it’s pretty much automated – we just let it do its thing." (read full review) WP Modula - "One of the reasons I’m personally a huge fan of ShortPixel is the built-in support for next-gen image formats like WebP." (read full review)
Yes, you can. As long as you have available credits, you can use a single API Key on as many websites as you wish!
Everyone has different needs, but generally, we recommend getting a One-Time plan to optimize your whole Media Library and then get a Monthly plan to optimize your future uploads. To learn more, have a look at this comparison
To know how many thumbnails you have, just install the plugin and go to Media > Bulk ShortPixel. The plugin will tell you how many thumbnails you've got. Based on this, have a look at our plans
Of course. You can upgrade or downgrade your plans in a couple of clicks from your account on shortpixel.com.
Yes, you can. We offer 100 free image optimization credits each month. Exceeding the monthly free quota will pause the optimization process till the quota is reset or extended by buying one of our plans.
Absolutely. You can actually optimize any image you have on your site regardless of its place. You just need to add - in the Advanced section of the ShortPixel Settings - the folders where the images you want to optimize are located and ShortPixel will work its magic and do the rest.
Sure! You can optimize all your past/current images and photos using our "Bulk ShortPixel" page in your Media with a single click.
Yes, that is correct. But please note that usually, an image in Media Library has 5 or more associated thumbs. Each optimized thumbnail requires a credit. In the rare cases when ShortPixel does not optimise the image (lossy) with at least 5%, the credit will not be consumed, though.
If you choose the "Image backup" option in Settings/ShortPixel then the original version of any optimized image or PDF will be saved in the backup folder. The original image is needed if you want to restore an image or if you want to convert an image from lossy/glossy to lossless or vice-versa.
