Help and FAQ
From shortcut to first mark.
The free Store listing is still a draft. Once FastMarkup is published, use these notes to set up the shortcut and troubleshoot capture or copy.
Quick fixes
Nothing happens on a page
Try the popup's Start annotating button on a normal HTTPS page. Chrome blocks internal pages. Reload the extension if it was updated.
Clipboard copy is blocked
Use the toolbar's Download control and attach the PNG manually. Check browser clipboard permissions and test in a supported paste target.
The page stays frozen
Press Escape or use the toolbar Close control. The overlay should be removed and the live page restored. If it is stuck, reload that tab.

Common questions
What does FastMarkup capture?
Only the visible viewport of the active Chrome tab at activation time. It does not stitch a full scrolling page.
Is the toolbar in the saved image?
No. Export combines the original screenshot with your annotations. Toolbar controls, toasts, and cursors are excluded.
Are screenshots saved automatically?
No. The free build keeps the active capture in memory and discards it when you close the overlay. Copy and Download are actions you choose.
Is Pro available?
No. Some Pro features exist in an unreleased draft, but paid activation and checkout are not available. See the Pro preview.
Where does the image go after I paste it?
FastMarkup does not upload it. The app you paste into handles the image under that app's own terms.
Does it work at every zoom level?
The extension is designed to map annotations to the captured image resolution. The full cross-site, zoom, and high DPI acceptance matrix is still pending.
