Speed matters. Here's how to get the fastest screenshots from our API.

## 1. Choose the Right Wait Strategy

load (default): Waits for page load event — fastest, works for most sites
domcontentloaded: Even faster, but may miss lazy-loaded content
networkidle: Slowest but most complete — use for SPAs

## 2. Format Matters

| Format | Size | Speed | Quality | |--------|------|-------|---------| | WebP | Smallest | Fastest | Good | | JPEG | Small | Fast | Good | | PNG | Largest | Slowest | Lossless |

Use WebP with quality 75 for the best size/speed/quality balance.

## 3. Viewport Size

Smaller viewports render faster. If you only need a thumbnail, use mobile viewport (375x667) instead of desktop.

## 4. Block Unnecessary Content

`json { "url": "https://example.com", "blockAds": true, "blockCookies": true, "format": "webp", "quality": 75 } `

Blocking ads and cookie banners can reduce render time by 30-40%.

## 5. Use Base64 for Inline Display

Add ?base64=true to skip file handling and get the image data directly in your JSON response.
