Documented steps Create and connect a session, then navigate to the target page (see create/navigate routes). Open a CDP session on the page: Playwright `const client = await context.newCDPSession(page);` (Puppeteer: `await page.createCDPSession();`). Capture a FULL-PAGE screenshot: `client.send("Page.captureScreenshot", { format: "jpeg", quality: 80, captureBeyondViewport: true })`. For a VIEWPORT-ONLY screenshot (just the visible area), drop captureBeyondViewport or set it to false. The response returns base64 in `data`; decode and write it: `Buffer.from(data, "base64")` / `base64.b64decode(...)`. Official doc: https://docs.browserbase.com/platform/browser/files/screenshots Known gotchas CDP screenshots are significantly faster than the framework screenshot methods — prefer them on Browserbase. For full-page captures you MUST set captureBeyondViewport=true, otherwise you only get the viewport. Use JPEG with a quality value (e.g. 80) for smaller files; PNG is larger but lossless.
