Image Cropper
Drag to select a crop area. Free, no signup, no upload.
How It Works
Select an image, then click and drag on it to draw a crop area. Click Crop Selection to extract that region. Download the cropped result. No file is ever uploaded to a server.
Why Crop Images?
Cropping removes unwanted parts of an image, helping you focus on the subject, straighten a composition, remove borders, or prepare images for profile pictures, thumbnails, and social media posts. The selection here is free-form — drag out any rectangle you like — and the live pixel readout lets you match a target size by eye as you drag.
Common Crop Sizes
Watch the pixel readout while you drag to get close to a size you need. These are widely used dimensions:
| Use | Dimensions (px) | Shape |
|---|---|---|
| Profile picture | 400 x 400 | Square (1:1) |
| Instagram post | 1080 x 1080 | Square (1:1) |
| Instagram story | 1080 x 1920 | Portrait (9:16) |
| YouTube thumbnail | 1280 x 720 | Landscape (16:9) |
| Facebook cover | 820 x 312 | Wide banner |
Frequently Asked Questions
How do I crop an image online?
Select an image, then click and drag across it to draw a rectangular selection. Click Crop Selection to cut out that region, then use Download to save it. The live readout shows the selection size in pixels as you drag.
Can I crop images on my phone?
Yes. The cropper supports touch, so you can drag out a selection with your finger on a phone or tablet just as you would with a mouse on a desktop.
What format is the cropped image saved in?
The cropped result is always saved as a PNG, named your-file-cropped.png. PNG is lossless, so the cut-out keeps the same quality as the original pixels.
Does cropping reduce the image quality or resolution?
No. The selection is mapped back to the full-resolution image, so the crop keeps the original pixel density. The file only contains the region you selected, at its native resolution.
Are my images uploaded to a server?
No. Cropping runs entirely in your browser on an HTML canvas, so your images never leave your device and nothing is uploaded, stored, or sent anywhere.
