Image Format

• PNG - better image quality but larger file size. Best suited for cropping and capturing simple web pages

• JPG - smaller file size with slightly lower image quality. Useful when capturing the entire screen area especially with lots of images on screen or when capturing still shots of videos. The quality of the JPEG can be adjusted from 100 to 0 (highest to lowest)

Screenshot Scaling

• Preserve scaling - the screenshot will be saved with the page scaling that you are seeing on the screen

• Downscale to actual size - on HDPI displays like Retina or zoomed pages the screenshot will be downscaled to the original page size

Save Format

• To File - save the screenshot to a file. Depending on your download preferences you will be either prompted to save the file or the file will be saved automatically in your download folder

• To Clipboard - copy the screenshot to your clipboard:

  • Data URL String - the screenshot will be copied to the clipboard as Data URL String
  • Binary Image - the screenshot will be copied to the clipboard as raw Binary Image
  • Confirmation Dialog - toggle the confirmation dialog on copy to clipboard

Save Location

Caveats

The extension won't work on the following origins:

• chrome and extension settings pages - chrome:// and chrome-extension://
• the official chrome web store - https://chromewebstore.google.com/
• your home page

To enable the extension on local file:/// URLs:

1. Navigate to chrome://extensions
2. Locate the Screenshot Capture extension and click on the Details button
3. Make sure that the Allow access to file URLs switch is turned on

Copy to clipboard:

• it won't work on domains served on insecure http:// protocol, but it will work on http://localhost
• when using Capture Viewport you will be asked by the browser to grant read access to the clipboard
• Capture Viewport won't work on PDF documents, use Crop and Save instead and select the entire screen area
