How to Edit a Screenshot on Chromebook (2026 Guide)

ChromeOS has solid built-in screenshot editing tools — most people just never find them. You can capture, crop, annotate, and share a screenshot without installing a single app or extension. And when you need more advanced edits like resizing, format conversion, or batch processing, web-based tools fill the gap perfectly because Chromebooks run everything through the browser anyway.

Here is how to edit a screenshot on Chromebook, from the quickest built-in method to full-featured web editors.

Method Comparison

Quick recommendation: For cropping and annotating a single screenshot, the Gallery app is fastest — it is already on your Chromebook. For resizing, format conversion, or editing multiple screenshots at once, Pixotter handles it in your browser with no uploads to external servers.

How to Take a Screenshot on Chromebook

Before you can edit, you need to capture. ChromeOS (version 130+) offers two approaches.

Keyboard Shortcuts

• Full screen: Press Ctrl + Show Windows (the rectangle-with-two-lines key, top row). The entire screen is captured and saved to your Downloads folder.
• Partial screen: Press Ctrl + Shift + Show Windows, then click and drag to select the area you want to capture. This is often faster than taking a full screenshot and cropping later.
• Single window: Press Ctrl + Alt + Show Windows, then click the window you want to capture.

Screen Capture Toolbar

Press Ctrl + Shift + Show Windows or click the clock in the bottom-right corner, then select Screen capture. The Screen Capture toolbar appears at the bottom of the screen with options for:

• Screenshot or screen recording (toggle at the left)
• Full screen, partial, or window capture (three icons in the center)
• Settings gear for timer delay and microphone options

After capturing, a notification pops up in the bottom-right corner. Click the notification thumbnail to open the screenshot directly in the Gallery app for editing.

Where screenshots are saved: By default, ChromeOS saves screenshots to Downloads/. You can change this by clicking the gear icon in the Screen Capture toolbar and selecting a different folder or your Google Drive.

Edit Screenshots with the Gallery App

The Gallery app is ChromeOS's built-in image editor. It opens automatically when you click a screenshot notification, or you can find it in the app launcher.

Open Your Screenshot

1. Click the screenshot notification that appears after capture, or
2. Open the Files app → Downloads → double-click the screenshot. It opens in Gallery by default.

Crop

1. Click the Crop & Rotate icon in the toolbar (overlapping right angles).
2. Drag the corner handles to select the area you want to keep.
3. Use the aspect ratio dropdown to lock proportions — Free, Square, or preset ratios.
4. Click the checkmark to apply.

Cropping is the most common screenshot edit. If you grabbed the full screen but only need one dialog box or one section of a webpage, crop out everything else. For more precise cropping with custom dimensions or batch processing, Pixotter's crop tool lets you enter exact pixel values and crop multiple screenshots at once.

Annotate

1. Click the Annotate icon (pencil) in the toolbar.
2. Choose your tool: Pen, Highlighter, or Text.
3. Pick a color and line thickness from the options bar.
4. Draw directly on the screenshot — circle a button, underline text, add a label.
5. Use Undo (Ctrl + Z) to remove mistakes.

Annotations are great for bug reports, tutorials, or highlighting something before sharing with a coworker. The pen tool works with both trackpad and touchscreen. If your Chromebook has a stylus (like the Pixelbook or Lenovo Duet), the pressure sensitivity makes annotations feel natural.

Rotate and Flip

Click the Crop & Rotate icon, then use the rotation controls:

• Rotate 90° clockwise or counterclockwise
• Flip horizontally (mirror)

These are useful when a screenshot captured a sideways mobile preview or when you need to mirror an interface element.

Resize

1. Click the three-dot menu (⋮) in the top-right corner.
2. Select Rescale.
3. Enter new dimensions. The aspect ratio locks by default — change the width and the height adjusts automatically.
4. Click the checkmark to apply.

The Gallery rescaling is basic — it works for simple dimension changes but does not let you target a specific file size or choose a resampling algorithm. For screenshots that need to hit a specific file size (email attachment limits, CMS upload limits), use Pixotter's resize tool which lets you target dimensions or file size.

Save

• Save (Ctrl + S) overwrites the original screenshot.
• Save as (Ctrl + Shift + S) creates a new copy.

Always use Save as if you might need the original later. ChromeOS does not have a built-in version history for local files.

Edit Screenshots with Google Photos

If you back up your Chromebook photos to Google Photos, you can edit screenshots there too. This works well when you want edits synced across devices.

Steps

1. Open photos.google.com in Chrome (or the Google Photos Android app if your Chromebook supports it).
2. Find the screenshot in your library. If it has not synced yet, upload it manually.
3. Click the screenshot to open it, then click Edit (sliders icon).
4. Use the Crop tab to crop and rotate.
5. Use the Markup tool (available on the mobile app and in the web editor under More) to draw, highlight, or add text.
6. Click Save copy to keep the original intact.

Limitations: Google Photos is best for quick crops and color adjustments. The annotation tools are more limited than the Gallery app — fewer pen options, no custom colors on the web version. And if the screenshot has not synced to the cloud, you need to upload it first, which adds friction.

Google Photos does apply strong compression when saving edits. If you need your screenshot at full quality (documentation, print), stick with the Gallery app or a web tool like Pixotter that preserves original quality.

Edit Screenshots with Web-Based Tools

Chromebooks are built around the browser, which means web-based image editors run just as well as native apps — sometimes better. Two standout options:

Pixotter

Pixotter processes images entirely in your browser using WebAssembly. Your screenshots never leave your Chromebook — there is no upload, no server processing, and no waiting.

What you can do:

• Crop to exact dimensions or aspect ratios (1:1, 16:9, 4:3, custom)
• Resize to specific pixel dimensions or target file size
• Convert between PNG, JPEG, WebP, and AVIF formats
• Batch process — drop 20 screenshots and crop, resize, or convert them all at once
• Pixelate sensitive information in screenshots
• Blur faces for privacy

Since Chromebooks handle everything through Chrome, Pixotter feels like a native app. No install, no extension, no account. Open the page, drop your screenshot, edit, download.

Photopea

Photopea is a full Photoshop-style editor that runs in the browser. It is overkill for basic screenshot edits, but useful when you need:

• Layer-based editing (compositing multiple screenshots)
• Advanced selection tools (magic wand, lasso)
• Text with custom fonts and effects
• PSD file support

Photopea is free but ad-supported. The interface mirrors Photoshop, so there is a learning curve if you have never used a professional image editor. For everyday screenshot editing, the Gallery app or Pixotter is faster.

ChromeOS Screenshot Keyboard Shortcuts

Keep this reference handy. All shortcuts work on ChromeOS 130+.

Tip: If you just need to paste a screenshot into a Google Doc, Slack message, or email, use Ctrl + Show Windows to capture, then Ctrl + V to paste directly from the clipboard. Skip the editing step entirely when no changes are needed.

Frequently Asked Questions

Where are screenshots saved on Chromebook?

By default, screenshots save to the Downloads folder. You can change the save location through the Screen Capture toolbar — click the gear icon and choose a different folder or your Google Drive.

Can I annotate a screenshot on Chromebook without an app?

Yes. The built-in Gallery app has pen, highlighter, and text annotation tools. Open your screenshot in Gallery, click the pencil icon, and draw or type directly on the image. No app install or extension needed.

How do I crop a screenshot to exact pixel dimensions?

The Gallery app lets you crop with preset aspect ratios but not exact pixel values. For precise dimensions, use Pixotter's crop tool — enter the exact width and height in pixels and crop to those dimensions. It runs in your browser, so it works perfectly on Chromebooks.

How do I convert a screenshot from PNG to JPEG on Chromebook?

ChromeOS saves screenshots as PNG by default. To convert to JPEG (for smaller file sizes), use Pixotter's convert tool. Drop your PNG screenshot, select JPEG as the output format, adjust quality if needed, and download. You can also convert to WebP or AVIF for even smaller files.

Can I edit screenshots offline on a Chromebook?

The Gallery app works fully offline. Web-based tools like Pixotter also work offline once the page has loaded, since all processing happens locally in your browser via WebAssembly — no internet connection is needed after the initial page load.

How do I blur or pixelate sensitive info in a screenshot?

The Gallery app does not have blur or pixelate tools. For pixelating parts of a screenshot or blurring faces, use a web-based editor. Pixotter offers pixelation tools, and Photopea has gaussian blur and mosaic filters.

Next Steps

Your Chromebook already has everything you need for basic screenshot editing. The Gallery app handles cropping, annotating, rotating, and resizing. For batch editing, format conversion, or privacy-focused tools like pixelation, Pixotter fills the gaps without leaving your browser.
