To crop an image in Paint 3D, click Canvas in the top toolbar, then drag the edge handles inward to trim the image to your desired area. You can also enter exact pixel dimensions in the width and height fields for precise cropping. The crop operation removes everything outside the canvas boundary permanently once saved.
Paint 3D’s crop tool works differently from selection-based cropping in traditional photo editors. Instead of drawing a crop rectangle over the image, you resize the canvas itself, and the image content outside the new canvas boundaries gets trimmed. This approach works well for trimming borders, removing unwanted edges, and cutting photos to specific aspect ratios. Microsoft discontinued Paint 3D in November 2024, but this guide covers the final version installed on Windows 10 and Windows 11.
Step-by-Step: Crop an Image in Paint 3D
- Open your image. Click Menu > Open > Browse files and select the image you want to crop. Paint 3D loads it at full resolution onto the canvas.
- Click Canvas. Select Canvas from the top toolbar. White circular handles appear on each edge and corner of the canvas, and the Canvas settings panel opens on the right.
- Position the image first. If you need to crop to a specific area that is not at the top-left corner, use Select all (Ctrl+A) to grab the image content, then drag it so the area you want to keep aligns with the top-left corner of the canvas.
- Drag the crop handles. Pull the right-edge handle to the left to trim width. Pull the bottom-edge handle upward to trim height. Corner handles adjust both width and height simultaneously. The gray area outside the handles will be removed.
- Enter exact dimensions (optional). In the Canvas settings panel on the right, type specific pixel values into the Width and Height fields. Uncheck Lock aspect ratio if you need independent width and height values. Check it to maintain proportional dimensions.
- Confirm the crop. Click anywhere outside the canvas handles, or click another tool in the toolbar. The canvas resizes to your specified dimensions, and content outside the boundary is trimmed.
- Save the cropped image. Click Menu > Save as > Image. Choose PNG for lossless quality or JPEG for smaller file size. The saved file reflects the new cropped dimensions.
Cropping to Common Aspect Ratios
| Use Case | Aspect Ratio | Example Dimensions |
|---|---|---|
| Social media profile photo | 1:1 (square) | 1080 x 1080 px |
| Instagram post | 4:5 | 1080 x 1350 px |
| YouTube thumbnail | 16:9 | 1280 x 720 px |
| Standard photo print (4×6) | 3:2 | 1800 x 1200 px |
| Widescreen wallpaper | 16:9 | 1920 x 1080 px |
| Letter-size document | 8.5:11 | 2550 x 3300 px (300 DPI) |
Paint 3D does not have preset aspect ratio options, so calculate your target dimensions beforehand and enter them in the Width and Height fields. For more detailed image editing, see our complete Paint 3D guide.
Tips for Better Cropping Results
Reposition before cropping. Since Paint 3D crops from the canvas edges inward, the area you want to keep must be positioned at the edges you are keeping. Select all content (Ctrl+A) and drag it to position the focal area correctly before adjusting the canvas handles.
Use Ctrl+Z to undo. If a crop removes too much, press Ctrl+Z immediately to undo. Paint 3D supports multiple undo levels within a session, though undo history clears when you close the file.
Crop before resizing. Cropping first and resizing second preserves more image quality than the reverse order. Resizing down and then cropping discards pixels twice, reducing sharpness.

Frequently Asked Questions
Can I crop to a circular or non-rectangular shape in Paint 3D?
The Canvas crop tool only supports rectangular cropping. For a circular crop effect, use Magic Select to extract a circular area of the image, place it on a transparent canvas, and save as PNG. The visible area will appear circular while the file remains rectangular with transparent corners.
How do I crop a specific area from the center of an image?
Select all content with Ctrl+A, then drag the image so the center area you want to keep is positioned at the top-left corner of the canvas. Then drag the right and bottom canvas handles inward to match your target dimensions. This effectively isolates any region of the original image.
Does cropping reduce file size?
Yes. Cropping reduces the total pixel count, which directly reduces file size. A 4000×3000 image cropped to 2000×1500 contains 75% fewer pixels. The exact file size depends on the export format: PNG preserves full quality at a larger size, while JPEG with compression produces smaller files.
Can I undo a crop after saving the file?
No. Once you save and close the file, the crop is permanent. The trimmed pixels are discarded from the file data. To preserve the original, use Menu > Save as instead of Save, which creates a new file and leaves the original image intact.
