Crop and Resize Images in Microsoft Paint on Windows 10 and 11 Without Stretching

Whether you are shrinking a phone photo for email, cutting excess background from a screenshot, or preparing an image to meet a website’s exact pixel requirement, Paint handles the essentials well. The key is knowing the difference between cropping and resizing, and saving the finished result as a new file so the original remains safely untouched.

Crop vs. resize: the important difference​

These two actions are often treated as interchangeable. They are not.

• Crop removes pixels from the edges of an image. Use it to cut out unwanted surroundings, tighten the composition, or isolate a section of a screenshot.
• Resize changes the dimensions of the entire image, such as reducing a 4,000 × 3,000-pixel photo to 1,200 × 900 pixels.

A crop can change the image’s shape or aspect ratio. A proportional resize keeps the same shape while making the image larger or smaller.

For example, a 4,000 × 3,000 photo has a 4:3 aspect ratio. If you resize it proportionally to 1,200 pixels wide, Paint calculates the corresponding height as 900 pixels. If you force it to 1,200 × 1,200 instead, the photo becomes square—and unless that is deliberate, people and objects may look suspiciously stretched. Nobody wants a family portrait where everyone has suddenly become a funhouse-mirror version of themselves.

Open the image safely in Paint​

1. Open File Explorer and locate the photo or image.
2. Right-click the file.
3. Select Open with > Paint.

Alternatively, open Paint from the Start menu and choose File > Open.

Before editing, it is wise to create a working copy:

1. In Paint, select File > Save as.
2. Choose a new filename, such as holiday-photo-edited.jpg.
3. Save it in a folder you can find again.

This means every crop and resize happens to the copy, not the original camera file. It is a small habit with a very good track record for preventing large regrets.

How to crop a photo in Paint​

Paint’s crop tool works by selecting the portion you want to keep, then deleting everything outside that selection.

1. Open the image in Paint.
2. On the toolbar or ribbon, select Select.
3. Choose Rectangular selection for most photo crops.
4. Click and drag across the part of the image you want to keep.
5. Adjust the selection handles until the frame covers the desired area.
6. Select Crop on the toolbar.

Everything outside the selected rectangle is removed.

Microsoft identifies Paint as one of the Windows tools that can crop a picture without requiring Microsoft 365. The practical advantage is that Paint performs a true crop on the image canvas rather than merely hiding unwanted edges inside a document.

Tips for a cleaner crop​

• Leave a little breathing room around faces, objects, or text.
• For screenshots, crop out browser tabs, taskbar clutter, usernames, or notification banners before sharing.
• Zoom in when precision matters. This is especially useful when trimming a screenshot around a dialog box or a product label.
• If the crop is wrong, press Ctrl + Z immediately to undo it.

Paint is best for freeform rectangular cropping. If you need a precise preset such as 1:1, 4:5, or 16:9 with an on-screen guide, the Windows Photos app offers preset aspect-ratio cropping tools.

How to resize an image to exact pixel dimensions​

Once the crop is complete—or before it, if the crop area is easier to judge at the original resolution—you can resize the image.

1. In Paint, select Resize from the toolbar.
2. The Resize and Skew window opens.
3. Under Resize, choose Pixels rather than Percentage.
4. Ensure Maintain aspect ratio is selected.
5. Type the required width in the Horizontal box.
6. Paint automatically calculates the matching height.
7. Select OK.

For example, to make a wide image suitable for a forum attachment or web upload, enter 1600 in the Horizontal field. With aspect ratio preserved, Paint changes the vertical measurement automatically rather than distorting the image.

The same dialog also supports percentage-based resizing. Entering 50 with percentage selected reduces both width and height by half. That is useful when a service simply says “make it smaller” rather than specifying a pixel measurement. The resulting file size, however, will not necessarily fall by exactly half; file format, image content, and compression all play a part.

What “Maintain aspect ratio” does​

An image’s aspect ratio is the relationship between width and height.

With Maintain aspect ratio enabled:

• Change the width, and Paint recalculates the height.
• Change the height, and Paint recalculates the width.
• The image keeps its original proportions.

With it disabled:

• You can set independent width and height values.
• You can intentionally make a 1,600 × 900 image into 800 × 800.
• You can also unintentionally stretch a landscape photo into a square, which is generally less artistic statement and more accidental office printer incident.

Disable it only when the image must fit a precise, non-proportional space and distortion is acceptable—or when you plan to crop afterward.

How to make a photo fit exact dimensions without stretching​

A frequent requirement is an exact size, such as 1,200 × 630 pixels for a social preview image or 800 × 800 pixels for a profile image.

If the original photo has a different aspect ratio, you cannot preserve every pixel, preserve the exact target dimensions, and avoid distortion all at once. One of those things must give.

The reliable sequence is:

1. Crop first so the image’s shape roughly matches the target.
2. Resize second using exact pixel dimensions.

For a square 800 × 800 result:

1. Crop the original image to a square-looking area, keeping the important subject inside the selection.
2. Select Crop.
3. Open Resize.
4. Choose Pixels.
5. Keep Maintain aspect ratio enabled.
6. Enter 800 as the width or height.
7. Confirm that Paint reports 800 for the other dimension too.

This crop-then-resize approach preserves proportions and produces predictable output. It is also why asking Paint to squeeze a 16:9 landscape directly into a square is usually the wrong move.

Save the edited image as a separate file​

After cropping and resizing, preserve the original by using Save as, not ordinary Save.

1. Select File > Save as.
2. Choose an image format.
3. Give the edited version a clear new name.
4. Select Save.

Which format should you choose?​

For a photograph, JPEG is normally the practical choice. For a screenshot of Windows settings, a dialog box, a spreadsheet, or a document, PNG is often better because it keeps text and sharp edges cleaner.

If Paint warns that a selected format may affect the image’s quality or transparency, pause before confirming. A PNG with transparent areas saved as JPEG, for instance, cannot retain that transparency.

Common Paint problems and quick fixes​

The image looks stretched​

Cause: Width and height were entered independently with Maintain aspect ratio turned off.

Fix: Press Ctrl + Z, reopen Resize, enable Maintain aspect ratio, and enter only one dimension.

I need an exact width and height, but Paint changes one of them​

Cause: Paint is correctly protecting the original proportions.

Fix: Crop the image first to approximately match the target shape, then resize. Only turn off proportion locking when stretching is truly acceptable.

I cropped the wrong area​

Fix: Press Ctrl + Z before closing or saving. If you have already saved over the original, recovery becomes far less certain—which is precisely why the Save As habit earns its keep.

The image file is still too large​

Fix: Reduce the pixel dimensions further, then save a copy as JPEG if transparency is not needed. Reducing a photo from 4,000 pixels wide to 1,600 pixels wide typically has a much larger impact than changing its filename extension alone.

The Crop button is unavailable​

Cause: No active selection exists.

Fix: Choose Select, draw a rectangular selection on the image, then choose Crop.

The practical five-minute workflow​

For most Windows 10 and Windows 11 users, the whole job comes down to this:

1. Open the picture in Paint.
2. Use Select and Crop to remove unwanted areas.
3. Select Resize.
4. Choose Pixels.
5. Keep Maintain aspect ratio enabled.
6. Enter the required width or height.
7. Use File > Save as to create a separate JPEG or PNG.

That is the dependable route for a smaller, cleaner image without sacrificing the original. Paint may not be an all-singing professional photo suite—and it makes no pretence otherwise—but for basic cropping and pixel-perfect resizing, it is exactly the right amount of tool.
