Set the screenshot viewport size
Use --window-size=WIDTH,HEIGHT to choose the viewport dimensions in pixels. For example:
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
--headless
--screenshot
--window-size=1280,1696
"https://example.com/"The dimensions set the viewport used for capture; they do not, by themselves, guarantee an image of the whole document. Chrome’s command-line reference also uses --window-size=412,892 as an example. Pick dimensions that match the desktop or mobile-like layout you need.

Allow time for a page to load
Add --timeout with a value in milliseconds when a page needs a brief wait before capture:

Pick the symptom - the matching free tool is one click away.
"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
--headless
--screenshot
--timeout=5000
"https://example.com/"This is a maximum wait, not a signal that every resource has finished loading. Chrome may capture after the timeout even if the page is still loading, so a fixed delay cannot ensure that all images, scripts, or dynamically rendered content are ready. The available options are documented in the Chrome command-line reference.

Viewport image or full-page image?
The command above captures a screenshot using the specified viewport. Raising the viewport height is not a reliable substitute for a full-page capture: the documented command-line reference does not establish that it will capture the complete scrollable document for arbitrary sites. If you specifically need a full-page screenshot, use a method that explicitly supports full-page capture and check its current documentation rather than assuming --window-size provides it.
Chrome Headless version note
Instructions for older Headless versions may not apply to current Chrome. The Chromium project’s README says that old Headless functionality was removed from the Chrome binary beginning with milestone 132; users who still need that old functionality are directed to the separate Chrome Headless Shell binary. Check your installed Chrome version if a legacy tutorial’s command behaves differently: Chromium Headless README.

Troubleshoot common problems
- “No such file or directory” for Chrome: The standard app-bundle path may not match your installation. Confirm where Chrome is installed and use the executable inside that app bundle; other channels and custom installs can differ.
- The image is the wrong size: Set the intended dimensions with
--window-size=WIDTH,HEIGHT. Remember these are viewport dimensions, not a guarantee of the document’s full scroll height. - Some content is missing: Try a longer
--timeout, but treat it only as a maximum wait. A page with asynchronous rendering may still be incomplete when Chrome captures it. - A legacy Headless command fails: Check the Chrome version and consult the Chromium project’s Headless Shell guidance for workflows that depend on old Headless.
Websites can differ in their rendering, authentication requirements, and dynamic-loading behavior. The documented command is not a guarantee that every URL will produce identical or complete output.
