What is Image Cropper?

An image cropper removes unwanted outer areas from an image, letting you focus on the most important part. This tool features a visual drag-to-crop interface — simply drag the corners or edges of the crop rectangle to define your area. Use preset aspect ratios for common social media and web dimensions, or enter exact pixel coordinates for precision. The rule-of-thirds grid overlay helps you compose visually balanced crops. Whether you need a square crop for Instagram, a 16:9 crop for YouTube thumbnails, or a custom crop for your website header, this tool gives you precise pixel-level control. The cropping happens entirely in your browser using the Canvas API — your images are never uploaded to any server. PNG transparency is preserved, and JPEG/WebP images are saved at high quality.

What aspect ratio should I use for social media?+
Use 1:1 for Instagram posts, 16:9 for YouTube thumbnails and Twitter headers, 9:16 for Instagram Stories and TikTok, 4:3 for Facebook posts. The preset buttons make this easy.
Can I crop to exact pixel dimensions?+
Yes. Enter exact width and height values in the input fields below the image. Combined with X and Y position, you have complete control over exactly which portion of the image is cropped.
Is transparency preserved?+

Can I undo a crop?+
The original image is preserved until you remove it. If you are not happy with a crop, simply drag the handles to adjust and crop again. The original is never modified.
Is my image uploaded to a server?+
