Where animation helps
Short-lived progress, recording, or urgent-state indicators can be useful when the tab is backgrounded.

Implementation choices
JavaScript can swap icon URLs or redraw a canvas favicon. GIF and animated SVG behavior varies across browsers, so do not depend on continuous playback.

A safe default
Ship a strong static icon first. If you add state, debounce updates, stop when hidden where appropriate, and always restore the canonical favicon.

Choose a state model before choosing animation
Define the event, maximum duration, update frequency, and stable resting icon. Progress, active recording, and an urgent failure can justify a temporary change; decoration that loops indefinitely usually adds distraction without information.
Keep the document title or in-page status synchronized so the favicon is never the only place where state appears. Stop updates when the task completes and revoke temporary object URLs when they are no longer used.
Implement and test a conservative fallback
The most interoperable approach is to swap static icon URLs or draw an occasional canvas frame. GIF and animated SVG playback varies by browser and surface, and saved bookmarks or home-screen icons may capture only one frame.
Test CPU use, tab backgrounding, private mode, saved bookmarks, and reduced-motion behavior. A strong static favicon must remain available when animation is paused or unsupported.

Questions, answered
Do animated favicons work on mobile?+
Not reliably across mobile browsers and home-screen surfaces.
Will animation hurt performance?+
Rapid canvas redraws or URL churn can. Keep frames and updates infrequent.
