MS Paint Undo Redo and Zoom

Every artist makes mistakes, and Paint forgives them. Undo reverses your last action. Redo brings it back. Zoom lets you step close to a picture or step back to see the whole scene. Together these three controls build confidence.

Undo

Undo takes your picture back by one step. Press Ctrl and Z, or click the curved arrow that points left in the toolbar. Paint removes your latest stroke, fill, paste, or edit. Press the shortcut again to go back another step.

What Undo Can Reverse

  • Brush and pencil strokes
  • Shapes, fills, and text
  • Pastes, cuts, and deletions
  • Resizing, rotating, and cropping

The Limit of Undo

Paint remembers many steps, but the memory has an end. A very long session may lose its oldest steps. Save milestone copies of your work when a picture grows complex.

Redo

Redo restores a step that Undo removed. Press Ctrl and Y, or click the curved arrow that points right. Use Redo when you go back too far. Redo works only until you perform a new action. A fresh brush stroke clears the redo steps.

Zoom

Zoom changes how large the picture appears on screen. The saved picture stays the same. A zoom level of 100 percent shows each pixel at actual size. Higher levels enlarge the view, and lower levels shrink it.

Ways to Zoom

The Zoom Slider

Drag the slider at the bottom right of the window. Click the plus and minus buttons beside it for small steps.

The Mouse Wheel

Hold Ctrl and roll the wheel. Roll forward to zoom in and backward to zoom out.

Keyboard Shortcuts

Press Ctrl and Plus to zoom in. Ctrl and Minus zooms out.

The View Menu

Open the View menu for zoom commands, including options to fit the picture to the window.

800 percentPixel art and single-pixel fixes

Work Habits That Use All Three

  1. Zoom in for a delicate stroke.
  2. Draw the stroke.
  3. Press Ctrl and Z if the stroke misses.
  4. Zoom out to judge the overall look.
  5. Repeat until the picture feels right.

Zoom Does Not Change Your Picture

Beginners sometimes worry that zooming alters the size of a saved file. Zoom only changes how large the picture looks on your screen. A zoom of 800 percent produces the same saved picture as a zoom of 50 percent. Compare a magnifying glass over a printed photo, because the photo itself stays the same while your view changes.

Undo Is a Safety Net for Experiments

Try a bold color, a huge brush, or a strange shape without worry. One keystroke returns the picture to its earlier state. Artists who feel safe experiment more, and experiments lead to better pictures.

Common Problems

Undo Stops Working

Paint reached the limit of remembered steps, or you closed and reopened the file. Closing a file wipes the history.

Redo Is Gray

No undone steps remain, or a new action cleared them.

The Picture Looks Fuzzy at Low Zoom

Shrinking the view blends pixels together. Return to 100 percent to judge sharpness.

Practice Exercise

Draw five random shapes. Press Ctrl and Z five times and watch each shape vanish. Restore them with five presses of Ctrl and Y. Zoom to 400 percent and add a small dot on one shape. Shrink the view to 50 percent and judge the full picture.
