How can I use ShortPixel with WordPress?
We have a popular, easy to use, lightweight and frequently updated WordPress image optimization plugin that you can use can freely use.
Lossy, Glossy or Lossless – which one is the best for me?Lossy is the best option for the 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 Insights 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 images remain untouched, then select this option.
Can I use the same API Key on multiple web sites?
Yes, you can.
As long as you have available credits you can use a single API Key on as many websites as you wish!
A credit equals an optimized image?
Yes, that is correct.
What types of formats can be optimized?
ShortPixel optimizes JPEG, PNG, GIF and PDF type of files. Also we offer the option to also generate (for no extra credits) the WebP version of the image, upon optimizing it.
Do you have one-time plans?
Yes we do.
The credits that come with our one-time plans never expire. Yummy! :-)
How does the plugin work?
Our light-weight plugin sends the original images to our Image Optimization Cloud where they are compressed. ShortPixel then downloads the optimized images and the unoptimized originals are replaced with the optimized versions.
Do you optimize the images in cloud?
Yes, all the images processsed 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
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.
How much is a credit?
A credit is used each time ShortPixel optimizes an image or thumbnail by at least 5%. If we're not able to optimize an image or thumbnail by at least 5% then no credit will be used :-)
Please also note that usually images in your Media Library have 3-5 thumbs associated and a credit will be used for each featured image or associated thumbnail that is optimized.
Why shall I use a wordpress plugin and not an offline tool?
Because ShortPixel algorithms were perfected while optimizing over a hundred and a half million real-life images.
ShortPixel not only offers the best compression for JPEG, PNG, GIF and PDF files but it also saves you a lot of time. You just install it on your site and then ShortPixel will take care that all the images on your site are immediately optimized after upload.
How does the one-time plan work?
After the free sign up, you can purchase a one-time plan for processing you images. You can use it for bulk optimizing your past gallery, or for optimizing new images uploaded to your website. The process is different because you pay for it only once. This plan is recommended for websites that have a large gallery that needs to be optimized.
My site is not in WordPress, can I still use ShortPixel?
Yes! If your site uses PHP then you can use our command line or web based tools. They are easy to install and operate and we're here to assist you in case you need it.
We also have an image optimization API that you can use in your own applications from any programming language.
Do you optimize existent WebP images?
No, but ShortPixel can generate (for no extra cost) the optimized WebP version of any JPG, PNG or GIF image that you're optimizing.
How can I pay?
We accept PayPal and (credit) card payments. If you cannot pay by any of these two means, please contact us and will work out a solution.
How do monthly subscriptions work?
After sign up, you can upgrade to the Short or Large monthly plans. Short and Large plans 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. :)
I want more!
The easiest way to quickly process more images, is to buy several one-time plans. With each purchase, the one-time plans will add up to your quota.
If you need even more, we can accommodate any demands. Contact us and we can choose together one of our enterprise plans tailored for your business.
What happens to my existing images?
Your existing images are replaced with the optimized ones.
If you choose the backup option then the originals will be saved in a separate folder so you can restore them, should you ever need/want to do that.
If I stop using ShortPixel will my images remain optimized?
Once optimized the images will remain optimized unless you explicitly choose to restore them. But why would you do that? :-)
Do I have to pay monthly or one time?
We have both options available.
One-time credits never expire but with monthly plans you pay less per credit. Check out our prices here
When can I cancel a monthly plan?
Whenever you want.
The credits you still have available for the current billing period will still be available until the end of the billing period. At the end of it, you won't be billed again and the plan will be reset to the free plan.
When do credits expire?
Monthly credits expire after 30 days while one-time credits never expire.
Will ShortPixel work if my website is using CloudFare?
Absolutely! Sometimes you'll need to make sure you whitelist some IPs, just contact us and we'll assist you with that.
What happens with my images on your servers?
The optimized images are kept on our servers for 2 hours so our image optimization plugin or you can download them. After this time the images are deleted according to the standards. The images are separately kept and processed for each customer to prevent any unautorized access.
Where is the backup folder located?
Your original images are saved in a backup folder located on your server at: /wp-content/uploads/ShortpixelBackups/
What happens after I optimize the 100 FREE images?
If you exhaust your free image credits, ShortPixel will stop optimizing. You can either wait for the next month's quota when your plan will renew, or change your plan.
