Use chromedp.Navigate to open the page, wait for its Hindi content and any required fonts to finish rendering, then call chromedp.FullScreenshot for a full-page PNG and save the returned bytes with os.WriteFile. For a visible element, use chromedp.Screenshot; for only the current viewport, use chromedp.CaptureScreenshot.
Capture a full Hindi webpage as a PNG
Install the chromedp Go package in your project, then use a browser context and run the navigation and screenshot actions in sequence. Replace the example URL with the Hindi page you want to capture.
package main
import (
"context"
"log"
"os"
"github.com/chromedp/chromedp"
)
func main() {
ctx, cancel := chromedp.NewContext(context.Background())
defer cancel()
var image []byte
err := chromedp.Run(ctx,
chromedp.Navigate("https://example.com/hindi-page"),
// Add a page-specific readiness action here if the page renders
// content or loads fonts asynchronously.
chromedp.FullScreenshot(&image, 100),
)
if err != nil {
log.Fatal(err)
}
if err := os.WriteFile("hindi-page.png", image, 0o644); err != nil {
log.Fatal(err)
}
}- Create a chromedp context. It controls the browser actions in the run.
- Navigate to the target page.
- Wait for any application-specific content or fonts that load after navigation.
- Capture the full page and write the PNG bytes to a file.
The value 100 selects PNG output for FullScreenshot. Other quality values produce JPEG, so use a different extension if you deliberately choose JPEG. The chromedp example uses the same navigation, screenshot, and file-writing pattern: chromedp README and examples.
Choose full page, viewport, or element
Use the action that matches the area you need; these screenshot helpers have different scopes.

| Goal | chromedp action | Result |
|---|---|---|
| Capture the whole document, including content below the fold | chromedp.FullScreenshot(&image, 100) |
Full-page PNG at quality 100 |
| Capture only what is currently visible in the browser | chromedp.CaptureScreenshot(&image) |
Viewport screenshot |
| Capture one visible page element | chromedp.Screenshot("main", &image, chromedp.NodeVisible) |
PNG clipped to the selected element’s bounds |
For an element capture, replace "main" with a selector that matches the page. The element screenshot API also supports a scale factor through ScreenshotScale. A selector that matches no visible node cannot produce the intended element capture.
Wait for Hindi text and fonts to render
chromedp drives Chrome; it does not provide a universal Hindi font or guarantee that Devanagari will render identically in every runtime. The browser needs to be able to render the glyphs, and a page using a web font may need additional time or a readiness condition after navigation.

- Compatible with Nintendo Switch 2’s new GameChat mode
- Crisp HD 720p/30 fps video calls with diagonal 55° field of view and auto light correction. Compatible with popular platforms including Skype and Zoom.
- The built-in noise-reducing mic makes sure your voice comes across clearly up to 1.5 meters away, even if you’re in busy surroundings.
- C270’s RightLight 2 feature adjusts to lighting conditions, producing brighter, contrasted images to help you look good in all your conference calls.
- The adjustable universal clip lets you attach the camera securely to your screen or laptop, or fold the clip and set the webcam on a shelf. You’re always ready for your next video call.
- Check the actual Chrome environment, especially if it is a minimal container, for Devanagari rendering capability.
- If the page loads content or fonts asynchronously, add a page-specific readiness action before the screenshot rather than assuming navigation completion means the page is ready.
- Inspect the resulting image in the same runtime where the capture runs. Confirm that Hindi glyphs are present and shaped correctly.
The chromedp documentation does not prescribe a Hindi font package or certify Devanagari output across environments. Font installation therefore depends on the browser image and operating environment; do not assume one package or configuration works everywhere.
Set viewport and headless runtime carefully
Viewport emulation
chromedp.EmulateViewport changes viewport metrics and touch emulation. Its documented default behavior forces landscape orientation and disables mobile and touch emulation unless options are supplied. If the capture needs a particular device layout, set the viewport and relevant emulation options deliberately.

FullScreenshot overrides device emulation settings. If later actions in the same browser session depend on the emulated device state, restore that state after the full-page capture.
Headless deployment
For headless execution, the chromedp project documents a chromedp/headless-shell image containing a headless Chrome build that chromedp can locate by default. Check the browser version and image contents used in your deployment: browser behavior and container contents can change.

Troubleshoot common capture problems
| Symptom | Likely cause | What to do |
|---|---|---|
| Hindi characters appear missing or as boxes | The Chrome environment may not have the needed glyph coverage, or the page’s font has not loaded. | Check the actual runtime’s Devanagari rendering and wait for the page’s font resources before capture. Inspect the saved image rather than relying only on a successful navigation. |
| The screenshot is blank or lacks dynamically rendered content | The page application or its content may still be loading after navigation completes. | Add a readiness condition tied to the page content, or wait for a known selector or other page-specific signal before capturing. |
| The output does not match the intended device layout | Viewport or device emulation was not set as required, or a full-page capture changed emulation state. | Configure the intended viewport and emulation options; restore device state after FullScreenshot if subsequent actions need it. |
| An element screenshot captures the wrong area | The selector identifies a different node than intended, or does not identify a visible element. | Use a selector that uniquely matches the visible target and confirm it on the loaded page. |
| The saved image cannot be opened as expected | The chosen extension may not match the screenshot format selected by the quality argument. | Use FullScreenshot(..., 100) for PNG, or use a JPEG extension when using another quality value. |
