Image Cropper
Crop images with custom or preset aspect ratios.
About This Tool
Image Cropper is a free online tool for cropping images to any custom size or standard aspect ratio — all in your browser without uploading. Use free-form drag-to-select cropping, or choose from presets: 1:1 (square), 4:3 (classic), 16:9 (widescreen), and 3:2 (photography). The result downloads as a lossless PNG immediately.
Cropping is handled entirely by the HTML5 Canvas API running in your browser. No files are transmitted to any server. The interactive selection overlay lets you click and drag to select a region, then adjust the handles to fine-tune your composition before applying. The final crop is lossless PNG for maximum quality.
Image Cropper is most used by content creators preparing images for social media with required aspect ratios, photographers cropping product or portrait shots, and developers trimming screenshots or UI mockups. The 1:1 and 16:9 presets cover the most common social platform requirements.
