How Full Page Screenshots Work
A standard screenshot captures only what fits inside the browser viewport — typically 768 to 1080 pixels of height. A full page screenshot goes further: it scrolls the entire document canvas and composites every section into one seamless image.
Site-Shot uses a real Chromium browser to render the page, execute JavaScript, load lazy images, and then capture the fully rendered document from the first pixel to the last.
When to Use Full Page Capture
- Landing page archiving — save a complete visual record of marketing pages before redesigns or A/B tests.
- Design review — save full page screenshots for designers and stakeholders without requiring them to visit the live site.
- Legal and compliance — capture entire terms of service, privacy policies, or product listings for evidence.
- Competitor analysis — document competitor pages in full for side-by-side comparison.
- SEO audits — visually inspect full page layout, content order, and above-the-fold elements.
Full Page Screenshot API
Automate full page captures with the Site-Shot API. Set full_size=1 in your API request to capture the entire document. Control the maximum height with the max_height parameter (up to 20,000 pixels).
Example API call:
https://api.site-shot.com/?url=https://example.com&userkey=YOUR_API_KEY&full_size=1&max_height=15000
Tips for Better Full Page Screenshots
- Enable No ads / No cookie to remove banners and overlays that clutter the capture.
- Use a wider viewport (1920 px) for desktop pages to avoid content reflow.
- Set a higher delay time in the API (
delay_time=3000) for pages with heavy lazy-loading. - Choose JPEG format for smaller file sizes when capturing very long pages.
