No browser runtime to maintain
Keep Python web apps and job workers from carrying a local browser runtime alongside the application environment.
HTML to JPEG with Python
Generate JPEG images with Python
No browser management required
Render HTML and CSS from Python without installing Chrome, running Playwright or Selenium, or building a separate image-storage pipeline.
- No browser processes to maintain
- Consistent managed Chromium rendering
- Complete Python request below

Python workflow
Test the render before adding it to Python
Adjust the HTML and CSS here, then use the Python example below instead of recreating the browser-rendering workflow locally.
Managed rendering
Skip the fragile parts of native Python browser automation
Keep the application code focused on the request and response while HCTI manages Chromium, render isolation, retries, and hosted output.
Predictable production rendering
Use managed browser versions, isolated render jobs, built-in timing controls, and consistent viewport behavior across deployments.
A usable image URL immediately
Receive the hosted .jpeg result without building a separate pipeline for temporary files, uploads, storage, and delivery.
HTML to image API
Send one Python request instead of running a browser
POST the HTML, CSS, and format from Python. HCTI handles the browser lifecycle and returns the generated .jpeg URL.
-
HTML and CSS input
Send complete markup and styles, including browser-supported fonts, images, SVG, and JavaScript.
-
JPEG output
Set format to jpeg and use the hosted .jpeg URL returned by the API.
-
Viewport and crop controls
Set viewport dimensions and device scale, or crop the result to a CSS selector.
-
Page environment
Choose light or dark mode, timezone, and screen or print media.
Request
How it works
From markup to a finished JPEG
-
Send HTML and CSS
Submit the content with format set to jpeg and any viewport or browser settings.
-
Chromium renders the design
The API loads the markup, styles, fonts, and assets in a managed browser environment.
-
Use the .jpeg URL
Embed the hosted result, download the file, or save it in your own storage and application records.
Output formats
One API, the format your workflow needs
Keep the same HTML and CSS. Choose lossless detail, compact compatibility, modern web delivery, or a paginated document.
