Infinite scroll pages (feeds, timelines, long docs) are one of the hardest targets for a “full page screenshot”.
They can load content while scrolling, reflow layout, or recycle DOM elements.
TL;DR
- Pre-load as much content as possible before capturing.
- Increase Scroll Delay for dynamic pages.
- For extremely long feeds on 4K/5K, make the browser window narrower.
- Consider exporting PDF if you want a document-style result.
Step-by-step: a reliable workflow
- Scroll slowly to load the sections you need.
- Pause and wait for images to finish loading.
- Start a Full Page capture.
- If you see missing images, retry with higher Scroll Delay.
Tip: If the page “jumps” while loading, stop scrolling and let it settle before you capture.
Why infinite scroll breaks captures
Many sites:
- Lazy-load images after scroll
- Load new sections asynchronously
- Re-render parts of the feed while you scroll (virtualization)
This can cause missing sections or repeated blocks in stitched screenshots.
Troubleshooting
- Missing images: increase Scroll Delay and retry.
- Very long feeds fail: narrow the browser window and retry (reduces total pixels).
- Need only a section: use Selected Area for the exact region.
