How to Resize an Image in Paint Without Stretching It
Use Paint’s resize controls to change the picture itself. Dragging the outside canvas edge can change the drawing area without proportionally resizing the image.
Resize the picture
- Open your image in Paint. Save a copy first if you need to retain the original.
- Open Resize from the Image controls. Paint versions that support it also use Ctrl+W for Resize and Skew.
- Choose Pixels for a specific width, or Percentage for a proportional reduction. Keep the aspect-ratio link enabled.
- Enter one dimension or percentage, apply the change, and save the output under a new name.
Pixels or percentage?
| Input | Example | Result |
|---|---|---|
| Pixels | 4000 × 3000 → width 1000 | 1000 × 750 with the ratio locked |
| Percentage | 4000 × 3000 → 50% | 2000 × 1500 |
| Canvas size | Extend the canvas edge | May add blank space instead of resizing the picture |
When you need a square
A rectangular photo cannot become square while keeping all its content and proportions unless you add padding. Crop a square composition first, or keep the original shape and use a layout that adds a border. Turning off the ratio lock and entering equal dimensions stretches the image.
Check the selection before resizing. If only part of the picture is selected, the operation may affect that part instead of the whole image. Menu placement and icon appearance differ between Paint versions.
Save in a suitable format
Use JPG for an ordinary photograph where a small file matters. Use PNG for sharp text, diagrams and transparency when supported by your workflow. Inspect the saved copy rather than relying only on the editing preview.
Resizing to 800 pixels does not guarantee a 100KB file. If a form requires a specific file-size ceiling, use target-size compression after the dimensions are correct.
Troubleshoot before trying again
If the result is distorted, undo and enable the aspect-ratio link. If a white strip appears, check whether you changed the canvas. If the file is larger despite smaller dimensions, compare its format with the original. Keep each new attempt based on the original rather than repeatedly recompressing the previous copy.
Frequently Asked Questions
Does Paint have an exact KB setting?
The resize controls change dimensions. Use a tool that measures the encoded output when you need a strict KB maximum.
Can I enlarge a small image?
You can create more pixels, but ordinary resizing does not recreate missing photographic detail.
