Convert to next-gen formats like AVIF and WebP
With the TinyPNG WordPress plugin, you can easily convert your images to next-gen formats like AVIF and WebP. AVIF and WebP are modern image formats designed for the web. They are often smaller in size than older formats like JPEG and PNG, while keeping excellent image quality.
WebP images are 25–34% smaller than JPEG (lossy) according to Google.
AVIF can reduce image size by up to 50% compared to JPEG, often even beating WebP in compression.
Google’s PageSpeed Insights and other tools strongly recommend serving images in AVIF or WebP. Most modern browsers (like Chrome, Firefox, Edge, and Safari) now fully support WebP and AVIF. That means you can safely serve these formats to most of your visitors.
With the TinyPNG WordPress plugin, your images can be automatically converted to AVIF or WebP when you upload them. No extra steps are required.
Optimizing all your images
You can bulk optimize your existing JPEG, PNG, and WebP images all at once by going to Media > Bulk TinyPNG. Clicking on the big button will start compressing and converting, when needed, all unoptimized images in your media library.
If you have more images than your free credits allow, the tool will show you an estimated cost to optimize your entire library. If you are interested, you can upgrade your account to the paid plan and optimize the full library all in one go. Prefer to stay on the free plan? No problem! The bulk optimization tool will simply process images until your free limit is reached.
Compress for performance
The Tinify optimization engine is more than just compression. It is built to deliver the best image performance for the web, without sacrificing visual quality. Here’s how it helps:
Display JPEG images more quickly with progressive JPEG encoding.
Color profiles are automatically translated to standard RGB color.
Convert CMYK to RGB to save more space and add compatibility.

Pricing
You get 500 credits per month at no cost.
With a regular WordPress installation, you can compress roughly 100 images per month. Please note that converting images to AVIF or WebP uses an additional credit per image size. This means with the conversion feature enabled, you can roughly compress and convert 50 images per month for free.
The exact number depends on how many thumbnail sizes are generated by your theme or plugins. You can choose which of the generated thumbnail sizes should be optimized by going to Settings > TinyPNG page. You can upgrade to a paid plan to remove the limit and compress as many images as you like.

Frequently asked questions.
Q: How many images can I optimize for free?
A: In a default WordPress installation you can optimize around 100 images for free each month. WordPress creates different thumbnails of your images which all have to be compressed. Some plugins even add more sizes, so take a look at the Settings > TinyPNG Image Optimization – Image Compression JPEG & PNG | Convert to WebP & AVIF page before you start optimization.
Q: How much does it cost to use the plugin?
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.
Q: How can I remove the 500 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.
Q: What happens to the optimized images when I uninstall the plugin?
A: When you remove the plugin all your optimized images will remain optimized.
Q: I don’t recall uploading 500 photos this month but my limit is already reached. How is this number calculated?
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.
Q: Is there a file size limit?
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).
Q: Can I use the same API key on all my websites?
A: Yes, there are no limitations. You can add the same key everywhere.
Q: Can I hide my API key from the admin?
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.
Q: What happens when I reach my monthly limit?
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.
Q: Can I optimize all existing images in my media library?
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.
Q: How do I switch to a paid account?
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.
Q: Does converting to AVIF or WebP use more credits?
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.
