FAQ

Before You Start

What does Smart Region Screenshot do?

Smart Region Screenshot helps you capture any part of a webpage as a high-quality image. Besides taking regular screenshots, it can also automatically reformat desktop webpages into a clean mobile-friendly layout, making them easier to read and share.

I already have Windows/macOS screenshot tools. Why should I use Smart Region Screenshot?

Built-in screenshot tools capture exactly what's on your screen. Smart Region Screenshot is designed specifically for webpages. It lets you precisely select content, optionally reformat it into a clean mobile layout, and add useful source information such as the page title, URL, and capture time. It's especially helpful for research, documentation, note-taking, and sharing webpage content.

Which capture mode should I choose?

Direct Screenshot captures the webpage exactly as you see it.
Mobile Reformat reorganizes the selected content into a clean, single-column mobile layout for easier reading and sharing.

What is Mobile Reformat?

Mobile Reformat automatically rearranges desktop webpage content into a clean mobile-friendly layout. Instead of wide multi-column pages, the exported image becomes a simple vertical layout that's much easier to read on phones.

Which mode is better for sharing on mobile?

In most cases, Mobile Reformat provides a better reading experience on mobile devices because it removes wide desktop layouts and presents content in a single column.

When should I keep the original webpage layout?

Choose Direct Screenshot when the webpage's visual layout matters, such as dashboards, tables, charts, design mockups, presentations, or any content where the original appearance should be preserved.

Getting Started

How do I start capturing?

Click the extension icon (or use the right-click menu), choose a capture mode, drag to select the area you want, then confirm to save the image.

Why do I need to select an area first?

Smart Region Screenshot is designed to capture exactly the part of the webpage you need. This gives you more control and avoids including unnecessary content.

Can I cancel a selection?

Yes. Press Esc at any time before confirming to cancel the current selection.

Which browsers are supported?

Smart Region Screenshot works in Google Chrome and most Chromium-based browsers that support Chrome extensions.

Do I need to refresh the page after installing Smart Region Screenshot?

Yes. If the webpage was already open before installation, refresh it once so Smart Region Screenshot can load correctly.

Can I use both capture modes on every website?

Most websites are supported. However, browser-protected pages, such as the Chrome Web Store and `chrome://` pages, cannot be captured due to browser security restrictions.

Taking Screenshots

Why doesn't the screenshot include the whole page?

Smart Region Screenshot captures only the area you select. If you need more content, simply select a larger region.

Can I capture the entire webpage?

Not yet. Full-page scrolling capture is planned for a future update.

Can I capture very long webpages?

Currently, you can capture any visible portion of a webpage. Automatic scrolling capture is not available yet.

Can I resize or reselect the capture area?

Yes. Simply start a new selection before confirming the screenshot.

Why is my screenshot different from what I see?

If you're using Mobile Reformat, this is expected. The content is rearranged into a mobile-friendly layout before being exported. If you're using Direct Screenshot, the exported image should match what you see on the screen.

Can I capture videos?

Yes. You can capture the current frame of a video, but Smart Region Screenshot does not record video.

Why are some pop-ups, menus, or floating elements missing?

Some temporary interface elements disappear automatically when the webpage loses focus or begins rendering. As a result, they may not appear in the exported image.

Does it work on PDF files opened in Chrome?

Yes, in most cases. PDF documents opened in Chrome can usually be captured just like normal webpages.

Can I capture content outside the visible browser window?

No. Only content that is currently visible in the browser window can be captured.

Can I capture multiple areas at once?

No. Each screenshot captures one continuous selected region.

Mobile Reformat

What does Mobile Reformat actually do?

It extracts the selected webpage content and reorganizes it into a clean, mobile-friendly layout before creating the screenshot.

Why does the reformatted result look different from the original webpage?

This is expected. Mobile Reformat rearranges desktop layouts into a simpler single-column format, making the content easier to read on smaller screens.

Will Mobile Reformat change the original webpage?

No. The original webpage is never modified. Smart Region Screenshot only creates a temporary layout for generating the exported image.

Which websites work best with Mobile Reformat?

Mobile Reformat works especially well for articles, blogs, documentation, tutorials, and other text-focused webpages.

Which websites may not work well with Mobile Reformat?

Highly interactive webpages, such as dashboards, maps, games, and video players, may not reformat as expected.

Can I choose a different mobile width?

Not yet. The current version uses a fixed mobile-friendly width that is optimized for readability.

Export & Image Quality

Where are my screenshots saved?

Screenshots are downloaded to your browser's default download folder.

Can I change the filename before saving?

Yes. You can enter a custom filename before exporting the image.

What are Metadata Footers?

Metadata Footers are optional information displayed at the bottom of the image, such as the webpage title, source URL, export time, and tool name.

Can I remove the footer?

Yes. Simply disable the footer options before exporting.

Why is the exported image so clear?

Smart Region Screenshot exports images in high resolution to keep text and graphics sharp, even on high-density displays.

Can I export in JPG or PDF instead of PNG?

Not at the moment. The current version exports images as PNG files only.

Can I change the image resolution?

Not in the current version. Smart Region Screenshot automatically exports images using high-quality settings.

Privacy & Permissions

Does Smart Region Screenshot upload my screenshots?

No. Everything is processed locally in your browser. Your screenshots are never uploaded to external servers.

Why does Smart Region Screenshot need permission to access webpages?

Smart Region Screenshot needs access to the current webpage so it can capture the content you select and generate the exported image.

Does it collect my browsing history?

No. Smart Region Screenshot does not track or collect your browsing history.

Can I use it on password-protected or internal company websites?

Yes. If Smart Region Screenshot is allowed to run on the page, it works the same way as on public websites. All processing remains local to your browser.

Does it work in Incognito mode?

Yes. Simply enable Allow in Incognito in your browser's extension settings.

Does Smart Region Screenshot work offline?

Yes. Most capture features work without an Internet connection, as long as the webpage is already available in your browser.

Troubleshooting

Why doesn't it work on the Chrome Web Store or chrome:// pages?

Chrome blocks all extensions from accessing certain protected pages for security reasons. This limitation applies to all screenshot extensions.

Smart Region Screenshot icon doesn't respond. What should I do?

Try refreshing the webpage first. If the problem persists, reload Smart Region Screenshot from your browser's Extensions page or restart the browser.

Why can't I start selecting an area?

Make sure the webpage has finished loading, then try again. If the page was already open before installing Smart Region Screenshot, refresh it first.

Why isn't the screenshot downloading?

Check whether your browser is blocking downloads and make sure your default download folder is available.

Why are some images or videos missing from the exported image?

Some websites restrict how protected media can be rendered or captured. In these cases, certain content may not appear in the exported image.

Why is the exported image blank?

This can happen on protected webpages or websites that restrict content capture. Try refreshing the page or testing on a different website.
