# Crop a photo to any shape or exact pixels

Updated 2026-11-09

To crop an image, drag a box over the part you want to keep and save what is inside it. Crop Image on ToolSugar does this in your browser, so the photo is not uploaded. Choose a free shape or lock the box to 1:1, 4:3, 16:9 or 9:16, then download the result. PNG and WebP files keep their format, and other types save as JPG.

## Crop an image in four steps

JPG, PNG, WebP, AVIF, GIF, BMP and HEIC files are accepted.

1. Add a photo.
2. Choose a shape: Free, 1:1, 4:3, 16:9 or 9:16.
3. Drag the box to move it and drag a corner handle to resize it.
4. Press Crop image, check the result, then download it.

## Which aspect ratio to choose

1:1 is a square, the usual shape for a profile picture. 4:3 matches many older screens and compact cameras. 16:9 is the wide shape of a video frame or a presentation slide. 9:16 is the same shape turned upright, used for stories and short vertical videos.

Free mode has no lock. Use it when you only want to trim the edges of a screenshot.

## Crop to exact pixel values

Under the picture are four fields: Left, Top, Width and Height. They measure from the top left corner of the original image, in whole pixels. They do not follow the smaller size the photo has on your screen.

Type the numbers when a form asks for a fixed size, or when you need the same crop on several photos taken with the same camera.

## Move the box with the keyboard

Focus the crop box, then press the arrow keys to nudge it. Hold Shift with an arrow to change its size. Keys give a steadier result than a trackpad when you need a pixel or two.

## Quality after a crop

The pixels inside the box are copied as they are. A PNG is saved with no loss. A JPG goes through the browser's encoder once more, so it picks up a small amount of extra compression.

## Questions

### Will the cropped file keep my format?

A PNG stays a PNG, a WebP stays a WebP and a JPG stays a JPG. Other types, such as GIF, BMP, AVIF or HEIC, are saved as JPG.

### Can I crop an iPhone HEIC photo?

Yes, HEIC is one of the accepted types. The cropped copy is saved as a JPG, so it opens in apps that do not read HEIC.

### How do I crop a screenshot to the part I need?

Add the screenshot, leave the shape on Free, and drag the box around the area. Press Crop image and save the result.
