Resize Canvas

The canvas is an area in Snagit Editor where your images can be viewed and edited.

Zoom In or Out

Use the Zoom controls to preview an image.

The zoom level does not change the final size of the image. It only applies to the image preview in Snagit Editor and the thumbnail size in the library.

Change the View Percentage

  1. Click the Zoom Options button above the Recent Captures Tray.
  2. Drag the Zoom slider or enter a percentage into the field.
  3. To reset the preview to the image's current size, click the Actual Size button.

Set the Zoom Preferences

The following options control the display of the capture on the canvas.

Example View Option

Fit to Screen

Display the selected capture to fit the canvas. This option sets the Zoom level based on Snagit Editor's window size.


Actual Size

Display the selected capture at its actual dimensions. This option sets the Zoom level to 100%.


Always Shrink to Fit

Change the Zoom level to fit the entire capture on the canvas for all open captures.

View the Pixel Grid (Windows)

The Pixel Grid view shows the pixel grid lines on the canvas for images previewed at 600 percent or higher.

  1. In Snagit Editor, select View > Pixel Grid.
  2. Click the Zoom Options button above the Recent Captures Tray.
  3. Enter a value of 600 percent or higher into the field.

The pixel grid lines appear on the canvas.

Resize an Image

Change the size of an image to specific dimensions in pixels, inches, centimeters, or by a percentage.

You must flatten any vector objects on the canvas to resize the image.

  1. To open the resize options, complete one of the following:
    • In Snagit Editor, select Image > Resize Image (Windows) or Edit > Resize Image (Mac).
    • Click the Resize Image dropdown above the Recent Captures tray.
  2. Select a unit.
  3. Enter a width and height. If you want to enter dimensions at a different aspect ratio than the current image, click the Lock Aspect Ratio icon.
  4. On Windows, click the Advanced option to display additional options.
    • Resolution: Sets the density of pixels in an image. Resolution is measured in DPI (dots per inch).
    • Use Resampling: Change the number of pixels in an image. Resampling up adds additional pixels to an image. Resampling down removes unnecessary pixels and can decrease the file size.

    It is recommended to use the other resizing options before enabling this option. This option can permanently degrade the quality of the image.

  5. Click the Apply button (Windows) or the Resize button (Mac).
