Limits and Pricing for Image Optimization

Image optimization pricing is dependent on your plan and on specific parameters outlined in the table below. For detailed pricing information for each region, review Regional Pricing.

This ensures that you only pay for the optimizations when the images are used instead of the number of images in your project.

Image Optimization on the Pro trial plan has the following limits.

Image transformations are billed for every cache MISS and STALE. The cache key is based on several inputs and differs for local images cache key vs the remote images cache key.

The total amount of Read Units used to access the cached image from the global cache, measured in 8KB units.

It is not billed for every cache HIT, only when the image needs to be retrieved from the shared global cache.

An image that has been accessed recently (several hours ago) in the same region will be cached in region and does not incur this cost.

The total amount of Write Units used to store the cached image in the global cache, measured in 8KB units. It is billed for every cache MISS and STALE.

You are billed for the number of Image Transformations, Image Cache Reads, and Image Cache Writes during the billing period.

Additionally, charges apply for Fast Data Transfer and Edge Requests when transformed images are delivered from Vercel's Edge Network to clients.

Image Optimization is free for Hobby users within the usage limits. As stated in the Fair Usage Policy, Hobby teams are restricted to non-commercial personal use only.

Vercel will send you emails as you are nearing your usage limits, but you will also be advised of any alerts within the dashboard.

Once you exceed the limits:

• New images will fail to optimize and instead return a runtime error response with 402 status code. This will trigger the onError callback and show the alt text instead of the image
• Previously optimized images have already been cached and will continue to work as expected, without error

You will not be charged for exceeding the usage limits, but this usually means your application is ready to upgrade to a Pro plan.

If you want to continue using Hobby, read more about Managing Usage & Costs to see how you can disable Image Optimization per image or per project.

For Teams on Pro trials, the trial will end if your Team exceeds the limits outlined in Pro trial pricing. For more information, see the trial limits.

Vercel will send you emails as you are nearing your usage limits, but you will also be advised of any alerts within the dashboard.

Pro teams can set up Spend Management to get notified or to automatically take action, such as using a webhook or pausing your projects when your usage hits a set spend amount.

For all the images that are optimized by Vercel, the following limits apply:

• The maximum size for an transformed image is 10 MB, as set out in the Cacheable Responses limits
• Each source image has a maximum width and height of 8192 pixels
• A source image must be one of the following formats to be optimized: image/jpeg, image/png, image/webp, image/avif. Other formats will be served as-is

See the Fair Usage Policy for typical monthly usage guidelines.
