No rate limits here. You’ll be able to create images up until you reach your account limit.
By default we render images for high resolution screens. This is known as
@2X. This ensures your image looks great on devices like iPhones and high resolution monitors.
You can adjust this back to
@1X by setting
device_scale:1 when creating your image.
Absolutely. All of our enterprise plans include an SLA. Contact us at email@example.com and we can build a custom plan for your specific needs.

url to your webpage to the API. Learn how to do that here: .
Alternatively, when passing your HTML to the API, include the full HTML markup. Starting and ending with the

All images served by the hcti.io domain are cached by Cloudflare’s global content delivery network. Bandwidth is unlimited and paid for as a part of your subscription.
Definitely. If you’re a student and using the API to build something cool. Email us and we’d be happy to add free images to your account.
The filename for your image is a randomly generated (and unique!) UUID. We currently do not have the option to set the filename.
v1/image namespace is shared by everyone who uses the API. Auto generating the file names makes your content more secure (hard to guess). We also use these long keys as partition keys for our infrastructure. This helps us scale the API for creating millions of images each month.
Using UUID’s helps us keep the service easy to use, fast and secure. Which is important to us.
We regularly keep HCTI up-to-date with the latest version of Chrome. We run a full test suite to ensure images render as expected before upgrading the API.
