Keys are stored in this browser only. A key lets you buy credits and keep going after the free runs.
How it works
- Paste your HTML into the field and set the width, format, and any other options you need.
- Press Run; the page renders the markup and produces the image file.
- Review the result and download it if it looks right.
Limits
The HTML input may be up to 2 MB and the rendered output may not exceed fifty million pixels total. Each run may take up to thirty seconds. Twenty runs a day are free with no login; after that each run costs three credits drawn from a prepaid balance tied to an API key.
Privacy
The HTML you submit is processed for that request and discarded immediately afterwards; it is not stored or used for any other purpose. Usage records retain only the time, tool name, status, duration, credits used, and a salted hash of the IP address.

Questions
Does the tool execute JavaScript in my HTML?
No. JavaScript is not executed; only the markup and any inline styles are rendered.
How do I get a transparent background?
Set the transparent option to true; this works with PNG and WEBP output only.
What happens after my twenty free runs?
Further runs cost three credits each, drawn from a prepaid credit balance attached to your API key.
How do I call this from code?
Send a POST request to https://data.voiddo.com/v1/html_to_image with your parameters as JSON; a curl example is shown on this page.
Is my HTML kept after the render?
No. The input is discarded once the request is complete and is not retained or used for anything else.
