Use Urlbox’s CLI in Terminal to capture a webpage from top to bottom and save it as an image: install the CLI, authenticate, then run urlbox screenshot https://example.com --full-page --output page.png. Replace the example URL and filename with your own. For automated jobs, set URLBOX_API_SECRET instead of signing in interactively. [Urlbox CLI Quickstart]
Capture a full page with Urlbox CLI on macOS
Open Terminal and install Urlbox’s command-line interface with npm. You need Node.js and npm available on the Mac; the command installs the CLI globally.

npm install -g @urlbox/cliurlbox login— complete the browser authentication flow.urlbox screenshot https://example.com --full-page --output page.png— replace the URL with the page to capture. The output file is saved in the current working directory. [Urlbox CLI Quickstart]
The --full-page flag requests the entire scrollable webpage rather than only the visible viewport. Use an appropriate file extension for the image format you want, such as .png. Urlbox’s CLI documentation also describes rendering controls for command-line captures. [Urlbox CLI Rendering]
Use the CLI in CI
For a non-interactive environment, configure the URLBOX_API_SECRET environment variable rather than running the interactive login step. Keep the secret in your CI platform’s secret manager; do not commit it to source control. [Urlbox CLI Quickstart]

Use the Urlbox API instead
If you want to request a render from an application rather than use the CLI, include the page URL and set full_page to true. Urlbox documents this JSON shape:
{"url":"https://example.com","full_page":true}The API supports full-page rendering options, including choosing the capture mode and controlling scrolling behavior. [Urlbox full-page capture documentation]
Choose between stitch and native capture
Urlbox documents two full-page modes. The default, stitch, scrolls the page, captures sections, and combines them into one image. Urlbox describes it as optimized for accuracy and its more reliable choice for most sites. The native mode uses the browser’s native full-page screenshot capability; it is faster, but Urlbox notes that it may be less accurate on some pages. [Urlbox full-page capture documentation]

To request native mode, add full_page_mode:
{"url":"https://example.com","full_page":true,"full_page_mode":"native"}For pages where completeness and seam handling matter more than speed, begin with the default stitch mode. Try native when faster rendering is more important and inspect the result for missing or distorted content.
Adjust full-page capture for difficult pages
Lazy-loaded images or content are missing
Urlbox’s stitch mode scrolls initially to trigger lazy-loaded content and establish the page’s scrollable height. If elements still appear only after additional time or more frequent scrolling, keep the initial scroll enabled, reduce scroll_increment, or increase scroll_delay. Urlbox lists 4096 pixels as its default section height and scroll increment, and 100 milliseconds as its default scroll delay; these are documented defaults and may change. [Urlbox full-page capture documentation]
Sticky headers repeat or seams appear
In stitch mode, Urlbox uses heuristics to identify fixed elements and capture them only once. If that handling is unsuitable for a particular page, set freeze_fixed: false. For diagnosis, enable show_seams: true to make stitching boundaries visible. [Urlbox full-page capture documentation]

Cookie notices, popups, or overlays cover the page
Try Urlbox’s click_accept and hide_cookie_banners options. These are automated controls, so check the output: the page’s particular consent interface or popup may not respond as expected. [Urlbox full-page capture documentation]
The page is extremely tall or uses infinite scroll
Use max_height to cap the output height or max_sections to limit stitched sections. Urlbox normally stops when it detects an infinite-scroll page; allow_infinite: true overrides that behavior. Use the override deliberately because an infinite feed may have no natural endpoint. [Urlbox full-page capture documentation]
The page scrolls horizontally
Set full_width: true along with full_page when you need the full scrollable width as well as the page’s full height. [Urlbox full-page capture documentation]
The capture should start below the top
Use scroll_to with a pixel offset or a CSS selector to choose a starting point. [Urlbox full-page capture documentation]

The output is too tall for JPEG or WebP
Urlbox documents maximum dimensions for JPEG and WebP and recommends PNG for full-page captures because PNG does not have the same stated image-dimension limitation. Choose the format based on the required dimensions and file characteristics. [Urlbox full-page capture documentation]

Why Mac screenshot shortcuts are different
macOS shortcuts capture the display, a selected region, or a window—not a webpage’s entire scrollable length. Apple documents Shift-Command-3 for the screen, Shift-Command-4 for a selected area, and Shift-Command-4 followed by Space for a window or menu. [Apple: Take a screenshot on Mac]
Safari’s File > Save As options include Web Archive and Page Source. A web archive can preserve graphics and working links when the destination webpages remain available; Page Source saves the HTML. Those are useful for saving or inspecting page contents, but neither is a single full-page screenshot image. [Apple: Save part or all of a webpage in Safari on Mac]

Can I capture a full-page screenshot with macOS’s built-in screenshot shortcuts?
No. The documented shortcuts capture the screen, a selection, or a window; they do not capture the full scrolling webpage.
Which Urlbox full-page mode should I try first?
Start with the default stitch mode for its accuracy emphasis. Try native when speed matters more, then inspect the result on the specific page.
