Image Cropper

Upload an image and crop it interactively using drag handles, preset aspect ratios, or custom dimensions. The Image Cropper provides a visual, intuitive interface for precisely selecting the portion of an image you want to keep, then downloading the cropped result in the original format.

Image cropping is one of the most common image editing operations. Whether you are preparing a profile photo for a social media platform, creating a thumbnail for a YouTube video, trimming unwanted borders from a screenshot, or extracting a specific region from a photograph, you need a tool that lets you define the crop area visually and precisely. This tool eliminates the need for desktop photo editing software by providing a full-featured cropping experience directly in your browser.

The tool renders your uploaded image on an HTML5 canvas and overlays an interactive crop region with draggable corner and edge handles. As you resize the crop area, real-time dimension indicators show the exact pixel width and height of the selection, so you always know the output size before committing to the crop. A live preview displays what the cropped result will look like, updated instantly as you adjust the selection.

Preset aspect ratios are available for the most common use cases: Free-form (no constraint), 1:1 (square — ideal for Instagram and profile photos), 4:3 (standard display and print), and 16:9 (widescreen — ideal for YouTube thumbnails, presentations, and desktop wallpapers). You can also enter any custom width-to-height ratio for specialized requirements. Once an aspect ratio is selected, the crop region maintains that ratio as you resize it, preventing accidental distortion.

The cropping engine uses the browser's native Canvas API to extract the selected pixel region and re-encode it in the original format. For JPEG and WebP outputs, a quality setting ensures the cropped image maintains your desired balance of file size and visual fidelity. The output image retains the full resolution of the selected crop area — no upscaling or downscaling is applied unless you explicitly specify output dimensions.

Supported input formats include PNG, JPEG, WebP, BMP, GIF (first frame), and TIFF. The output is downloaded in the same format as the original image. For format conversion, use the Image Format Converter tool after cropping.

All processing happens entirely in your browser. Your images are never uploaded to any server, never stored in any cloud, and never accessible to third parties. The tool works offline once loaded and handles all computation locally on your device.
