The result is a browser-emulated screenshot, not a photo or capture from physical iPhone hardware. If you need only particular dimensions, set an explicit viewport instead.
Use an iPhone device profile
This runnable Node.js example uses Playwright’s Chromium browser and the iPhone 13 profile documented in Playwright’s device emulation guide. Device profiles include browser parameters such as viewport, screen size, user agent, and touch capability. Confirm that the named profile exists in the device registry for the Playwright version installed in your project.

The default screenshot is the current viewport. The navigation waits for the page load event; sites that continue rendering content afterward may need an additional wait strategy, described below.
Choose a device profile or an exact viewport
Use a named profile when you want a coordinated set of emulated device settings, not just a width and height. Use an explicit viewport when exact dimensions are the only requirement. Playwright documents both context configuration and page-level viewport changes in its emulation guide.
| Method | Best suited to | What it configures |
|---|---|---|
| Named device profile | Emulating a device-style browser setup | A bundle of settings, including viewport, screen size, user agent, and touch capability |
| Explicit viewport | Controlling exact width and height | Viewport dimensions; it does not by itself supply the other profile settings |
To override a profile setting, put the explicit value after the profile spread; later object properties take precedence:
Recommended Free Tools
const context = await browser.newContext({
...devices['iPhone 13'],
viewport: { width: 390, height: 844 },
});The dimensions above are an illustrative explicit viewport, not a claim that every iPhone has those dimensions. For viewport-only emulation, omit the device spread:
const context = await browser.newContext({
viewport: { width: 390, height: 844 },
});You can also change a page’s viewport after creating it:

await page.setViewportSize({ width: 390, height: 844 });That changes the viewport dimensions; it does not turn the context into a complete named device profile.
Capture the first screen or the whole page
page.screenshot() captures the visible viewport by default, which is usually the right choice for checking the initial mobile layout. Set fullPage: true to capture the full scrollable page, including content below the fold. The screenshot API documents these options and supported output formats in the page screenshot reference.

fullPage: true,
scale: 'css',
});Full-page capture can produce a very tall image on long pages. Use viewport-only output when you need to review the first screen or keep the image to a predictable height.
Select image format and raster scale
Playwright supports PNG, JPEG, and WebP screenshots. The file extension can determine the output format; you can also specify type explicitly. Select the scale according to the image’s intended use:
| Scale | Output behavior | Useful when |
|---|---|---|
css |
One output pixel per CSS pixel | You want compact output dimensions aligned with CSS layout dimensions |
device |
Output uses device-pixel resolution and can be larger, especially for high-DPI settings | You need the emulated device-pixel resolution for downstream use |
For example, use a WebP filename and device scale for a viewport capture:

await page.screenshot({
path: 'mobile-page.webp',
scale: 'device',
});To set a format independently of the filename, specify it directly, for example type: 'jpeg'. These format and scale choices change the output image, not the fact that rendering is emulated. See the screenshot API options for the supported parameters.
Use Playwright Test or codegen when they fit your workflow
Playwright Test projects
In Playwright Test, configure a project with a named device profile by spreading it into use:
import { defineConfig, devices } from '@playwright/test';
export default defineConfig({
projects: [
{
name: 'iPhone 13 emulation',
use: { ...devices['iPhone 13'] },
},
],
});Alternatively, set a project viewport when dimensions alone are what matters. The same ordering rule applies: place explicit overrides after the spread.
Code generator
To launch Playwright’s code generator with a named profile, run npx playwright codegen --device="iPhone 13" https://example.com. For an explicit viewport rather than a named device, use --viewport-size="800,600"; that option specifies dimensions and is not a substitute for a device profile. See the codegen guide.
Make captures more reliable
A page’s load event does not guarantee that every image, animation, API-driven component, or lazy-loaded section has finished rendering. Choose a wait that matches the page rather than relying on an arbitrary delay for every site:

-
Wait for a meaningful element when the page has a clear completion signal:
await page.locator('main').waitFor({ state: 'visible' });. -
If content appears after a known interval, add a deliberate delay with
await page.waitForTimeout(1000); adjust it to the page, and avoid treating a fixed pause as proof that all content is ready. -
For content below the fold that loads on scroll, full-page capture may not cause every site’s lazy content to load. If missing content matters, scroll through the page before capturing or use a site-specific readiness condition.
Screenshot output can vary with the host operating system, browser version, settings, hardware, power source, and headless mode. For visual comparisons, create and update baselines in a consistent environment, and inspect a new baseline before accepting it. Playwright’s visual comparisons guide discusses these sources of rendering differences.
A one-off file capture and a visual regression assertion are different workflows. Use page.screenshot() to save an image directly. Use Playwright Test’s expect(page).toHaveScreenshot() when you want an assertion comparing a page against a screenshot baseline.

Troubleshoot common problems
-
“Cannot read properties of undefined” for a device name: The installed Playwright version may not include that registry entry, or the name may be misspelled. Check the available device names for that installed version and use one of those, or configure an explicit viewport.
-
The capture has desktop dimensions: Check that the context was created with the device profile or viewport before the page was created. When overriding a profile, ensure the explicit
viewportappears after the spread. -
The image stops at the first screen: That is the default viewport capture. Set
fullPage: truewhen you need the scrollable page.Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy. -
The image is unexpectedly large: Check whether
scale: 'device'is producing device-pixel output. Choosescale: 'css'for one output pixel per CSS pixel. -
Images or page content are missing: The page may still be rendering after navigation, or the content may be lazy-loaded. Wait for a relevant selector or condition; for below-the-fold content, scroll before capture if needed.
-
Visual snapshots differ between machines or runs: Rendering can depend on the browser and host environment. Keep the environment consistent and review changed baselines rather than assuming the page alone caused the difference.
