How to Take a Full-Page Web Screenshot on a Mac with Browser Extensions

Learn how to capture an entire webpage on a Mac with built-in browser tools or extensions, including steps for Safari, Chrome, and Firefox.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To capture a whole webpage on a Mac, use your browser’s full-page screenshot feature or a browser extension’s full-page command. A normal Mac screenshot captures only what is visible on screen; a full-page capture includes content below the viewport. If you prefer not to install an extension, Safari and Chrome offer developer-tool routes, while Firefox has a direct page menu option.

Choose a full-page capture method

Browser or method Where to start Best fit
Safari built-in Develop menu > Show Web Inspector Capture without adding an extension
Chrome built-in Developer Tools > Toggle Device Toolbar Capture without adding an extension
Firefox built-in Right-click page > Take a Screenshot Quick capture, download or clipboard copy
Browser extension Toolbar icon > full-page command Convenient repeat captures or extra export options

Prepare the webpage before capturing

  1. Open the page and wait for its main content to load.
  2. If the page loads images or other content only as you scroll, scroll all the way to the bottom once, then return to the top. This can prompt below-the-fold content to load before capture.
  3. Close or move anything that should not appear in the screenshot, such as menus or dialogs.
  4. Choose an image for visual sharing or editing. Use PDF when a document-style output is more useful, if your chosen tool supports it.

Use Safari’s built-in full-page screenshot

  1. In Safari, open Settings. In some versions this is called Preferences.
  2. Open Advanced and enable the option to show web developer features or the Develop menu. The exact wording may vary by Safari version.
  3. Open the webpage, then choose Develop > Show Web Inspector.
  4. In the Elements tab, right-click the first html line and choose Capture Screenshot.
  5. Save the generated image.

This route uses Web Inspector rather than a toolbar extension. If you specifically want a one-click extension workflow, see the extension steps below.

Use Chrome’s built-in full-page screenshot

  1. Open the webpage in Chrome.
  2. Open Developer Tools from Chrome’s More Tools menu.
  3. Click Toggle Device Toolbar.
  4. Open the menu in the left-hand page panel and choose Capture full size screenshot.
  5. Open the downloaded image from your Downloads location.

Use Firefox’s built-in screenshot

  1. Right-click the webpage and choose Take a Screenshot.
  2. Select Save full page.
  3. Choose Download to save an image, or Copy to put it on the clipboard. On macOS, Mozilla documents Command+S for saving and Command+C for copying.

Firefox also has a DevTools route: enable the “Take a screenshot of the entire page” toolbox button in DevTools Settings, then click that button. For a console-based option, Firefox’s Web Console helper :screenshot --fullpage saves a screenshot beyond the current window bounds.

Capture a full page with a browser extension

  1. Install an extension from your browser’s extension store and review its current permissions and data practices before enabling it.
  2. Open the webpage you want to capture. Scroll through the page first if it contains lazy-loaded images.
  3. Click the extension’s toolbar icon.
  4. Choose its full-page capture command and wait for the capture to finish.
  5. Save or export the result using the options the extension provides.

Awesome Screenshot

The vendor’s help instructions, updated December 24, 2025, describe these commands: in Chrome-compatible browsers, click the extension icon, select Capture, then Full Page; in Safari, choose Capture Full Page; in Firefox, choose Capture Entire Page. Labels and interface details can change, so follow the current extension UI if they differ.

A Mac tutorial updated March 6, 2026, says its Awesome Screenshot Safari installation may require enabling the extension in Safari Settings and granting a screen-recording permission. Permission requirements are extension-specific; check the prompt for the extension you install rather than assuming all add-ons need the same access.

GoFullPage

The Firefox Add-ons listing describes GoFullPage as a scrolling capture extension with PNG, JPEG, and PDF export. It also says the extension can split a very large capture into multiple images if one image exceeds browser storage limits. Its listing describes crop, annotation, and emoji editing as features of a premium editor; these are vendor-listed capabilities, not a guarantee that every page will capture identically.

Troubleshoot a missing or incomplete screenshot

Below-the-fold images are missing

The page may load images only when they approach the viewport. Scroll to the bottom before starting a full-page capture, then return to the top and capture again.

The extension cannot capture the page

Extension behavior depends on the page, browser, and permissions; there is no universal compatibility guarantee. Try the browser’s built-in method, such as Firefox’s Take a Screenshot menu or the Safari or Chrome DevTools route.

The image is too large or the page is very long

A very long capture may exceed browser storage limits. The GoFullPage Firefox listing says it can split an oversized result into multiple images. If your extension does not offer splitting, try a browser’s built-in route or choose a tool with an output option suited to the page.

The extension asks for permissions

Read the current browser-store listing and the permission prompt before allowing access. Permissions differ among extensions; use the browser’s built-in feature if you do not want to install or authorize an add-on.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Which route should you use?

  • For no-install capture: Firefox has a direct context-menu workflow; the documented Safari and Chrome built-in methods use developer tools.
  • For a toolbar action: use a full-page command in an extension such as Awesome Screenshot, checking its current browser-specific labels.
  • For PDF export or oversized captures: check the extension’s stated export and splitting options. GoFullPage’s Firefox listing describes PNG, JPEG, PDF, and splitting for very large captures.
  • For privacy-sensitive pages: check the extension’s current permissions and data practices, or use a built-in browser feature when installing an add-on is unnecessary.

Frequently Asked Questions

How do I take a scrolling screenshot on a Mac?

Use a browser’s full-page screenshot feature or a full-page extension command; scrolling is useful beforehand on pages that load content as you move down.

Does a full-page screenshot include content below the browser window?

Yes. A full-page capture is intended to include the webpage beyond the currently visible viewport, unlike an ordinary screen capture.
