Podifai is designed to have minimal impact on your store’s loading speed. Here’s how we keep things fast, and what you can do to optimize further.
How Podifai Loads
- Deferred loading — Podifai’s script loads after your page’s critical content, so it doesn’t block your initial page render.
- CDN-delivered assets — All scripts and images are served from a global CDN for fast delivery worldwide.
- Native form injection — Options are injected into your existing product form rather than loading a separate iframe or widget.
The live preview composites image layers on the client side (in the browser). This means:
- No server round-trips per selection — updates happen instantly
- Cached images — After the first load, option images are cached in the browser
- Typical update time — Under 100ms per selection change
Optimization Tips
Image Sizes
| Image Type | Recommended Size | Maximum |
|---|
| Base product image | 500–1000KB | 2MB |
| Option layer (swatch) | 50–200KB | 500KB |
| Customer upload | N/A (user-controlled) | 10MB |
Compress PNGs with tools like TinyPNG before uploading. A 50% file size reduction is common with no visible quality loss.
Option Count
There’s no hard limit, but performance considerations:
| Options per product | Impact |
|---|
| 1–10 | No noticeable impact |
| 10–20 | Minimal impact; use accordion mode |
| 20+ | Consider conditional logic to load options progressively |
Theme Compatibility
Some themes load heavy scripts that can compound with any app. If your page feels slow:
- Use your browser DevTools → Network tab to identify the largest requests
- Check if the slowdown is from Podifai or other apps/theme scripts
- Contact us if you need help diagnosing
Core Web Vitals
Podifai is built to preserve your store’s Core Web Vitals scores:
- LCP (Largest Contentful Paint) — Not affected, as Podifai loads after critical content
- CLS (Cumulative Layout Shift) — Minimal, since options inject into the existing form layout
- INP (Interaction to Next Paint) — Option selections respond in under 100ms
