TinyPNG – JPEG, PNG & WebP image compression

A: The plugin is free to use, you receive 500 free compressions each calendar month.
If you need to compress more, you can upgrade to the pay-per-compression pricing. You can view the current pricing at tinify.com.
When you use the bulk optimization tool, the plugin will first scan your media library and show you an estimated number of credits needed to optimize all uncompressed images. You can decide whether you want to upgrade your plan or stay within the free limit.

A: Just add your Payment details on your account dashboard to remove the limit. For a small fee the additional compressions above 500 will then be charged to your account at the end of each month.

A: When you remove the plugin all your optimized images will remain optimized.

A: When you upload an image to your website, WordPress will create different sized versions of it (see Settings > TinyPNG). The plugin will compress each of these sizes, so when you have 100 images and 5 different sizes you will do 500 compressions.

A: Yes, but they are very generous! The maximum file size is 500MB and the maximum canvas size is 256MP (16000px by 16000px in any ratio).

A: Yes, there are no limitations. You can add the same key everywhere.

A: Yes, you can hide your API key from the admin so other admin users will not be able to see it. To do this you should define the API key in your wp-config.php file. See the installation instructions for more information.

A: Everything will keep on working, but newly uploaded images will not be optimized. Of course we encourage everyone to switch to a paid account to cover the hosting and development costs of the service.

A: Yes! After installing the plugin, go to Media > Bulk TinyPNG, and click on the start button to optimize all unoptimized images in your media library.

A: You can upgrade to a paid account by adding your Payment details on your account dashboard. Additional compressions above 500 will then be charged at the end of each month as a one-time fee.

A: When the conversion feature is enabled (to convert images to AVIF or WebP), each image will use double the number of credits: one for compression and one for format conversion.
