What does this tool do?
Image Cropper lets you load any image into your browser, drag a selection box over it, and crop out exactly the region you want. You can download the result as a PNG with one click while keeping the original quality intact. Everything runs on your device, so no file is ever uploaded to a server.

- See the result in the live preview.
- Copy the generated CSS/code into your project.
How it works
After you choose an image, you draw a rectangular selection over it; drag the corners to resize the region or move the whole box around. The tool redraws the selected area onto an HTML canvas and exports it as a PNG. This lets you pull a precise frame out of an avatar, cover image, or screenshot in seconds.
Common use cases
Squaring up profile photos, grabbing just the relevant part of a screenshot, and resizing product shots to social-media dimensions are the most frequent scenarios. Designers extract detail crops from mockups while bloggers quickly prepare featured images. Because nothing is uploaded, you can safely work with private or sensitive images.
Frequently asked questions
What format is the cropped image downloaded in?
The cropped region is always downloaded as a PNG. Since PNG is lossless, edge sharpness and transparency are preserved, which makes it ideal for logos and screenshots.
Can I lock the selection to a specific ratio?
You can freely drag the selection by its corners to any size you like. If you want a square result, simply drag so the width and height match by eye.
