MegaOptim is image optimization plugin and that is easy to use, stable and actively maintained by dedicated team of experts. 🙂
The plugin uses minimal resources on your server and all the heavy lifting is done by our API service on our servers. No binaries will be ever installed on your server that will slow down your site.

Developer Hooks / CLI
Click here to read more about our WP CLI integration and the actions and filters that are available.
1.) Sign up for api key at https://megaoptim.com/register
2.) You will receive your API key in the email address you provided.
3.) Upload the MegaOptim plugin to /wp-content/plugins or install it via the wp-admin interface, finally activate it.
4.) Navigate to wp-admin and in the sidebar menu click on «MegaOptim», hover over and go to «Settings», here you can paste the api key and save the settings.
5.) In the same section check the other settings, change them according to your needs.
6.) You are all set! Begin optimizing by navigating to «MegaOptim» > «Optimizer» ( In the top right corner you can select optimizer )
What is API token?
One API token is one image. Please note that WordPress generates multiple thumbnails per one image. You will be charged one token for each thumbnail. If the total saved size per image is less than %5 you will not be charged.
Can I use the same API Key on multiple websites?
Absolutely. You can use your API key on as many websites as you want, or you can also create subaccounts for each of the sites you manage if you want to keep the things separate or bill your clients separate.
Do you offer CDN?
No, but our plugin integrates with WP Offload Media and that way you can easily use Amazon S3 bucket as your CDN which is much cheaper than actual CDN service.
Is the plugin compatible with WP Offload Media?
Yes. If you have configured WP Offload Media no further configurations are needed, the images will be automatically optimized and offloaded to your S3 bucket.
How the WebP feature works?
The WebP versions are free of charge and our API service will create optimized WebP for each image upon optimization and store it in your storage. If you enable Front-End delivery the content will be re-written and if .webp version exist for specific image it will be used instead.
Can I back up and restore the images?
Yes, MegaOptim have option to back up the images, and it is enabled by default. You can alawys restore the original images if there is backup.
Can I manage multiple sites separately with subaccounts?
Sure! You can create subaccount for your client and transfer tokens to the subaccount balance. This way your client will have separate account and api key and you will be managing it. You have the option to add or remove api tokens from it.
Is WP CLI (command line) supported?
Sure! You can optimize and restore images from the command line using WP CLI. Please see this guide for more information.
How to delete the MegaOptim database data?
To delete the database data, set define(‹WP_DEBUG›, true) in wp-config.php, navigate to «Settings» > «MegaOptim» > «Advanced» and in the bottom you will see the option «Delete MegaOptim database metadata». Use it with caution and read about the consequences.
Is this plugin heavy for my site?
The plugin optimizes images on our external servers and does not run anything on your own servers that may cause slowndowns. In addition, it only runs when you start bulk process or if you upload image via Media Library to autoamatically optimize it. It’s not active in background unlike some other plugins.
I used ShortPixel, Imagify and other plugins. Will your plugin reduce the images size furthermore?
In most cases yes! The plugin will make attempt to optimize the image further. If the saved size result is less or equal to 5% no token will be charged!
What happens if i stop using or deactivate MegaOptim plugin?
Nothing, your images will remain optimized, if you used the WebP feature the site won’t serve WebP any longer.
What are the pricing packages?
We do both one-time and monthly. Please check out here.
Can I cancel my subscription?
Absolutely! You can cancel your subscription whenever you want.
Do you have an API?
Will MegaOptim work with CloudFlare?
Yes! You need to use the CloudFlare plugin with correct credentials or setup credentials in the Settings > Advanced menu. If the credentials are set up correctly, the plugin will automatically purge from the CloudFlare cached images when they are optimized with MegaOptim.
Do you have referral program?
Sure! Help us spread MegaOptim and earn 120 tokens per sign up and 300 tokens once customer becomes paid customer. Our Referral program can be found in the dashboard area.
