Crop image online by selecting the exact region you want to keep using an interactive canvas. Set crop boundaries by dragging or entering pixel coordinates, then download the trimmed result. This free browser-based tool processes your image locally with no signup or server upload required.
The Image Cropper lets you crop images to precise dimensions or specific aspect ratios directly in your browser. Upload any JPEG, PNG, or WebP image and use the interactive crop handles to select the area you want to keep. Precise pixel dimensions can be entered manually for exact size requirements. Preset aspect ratios are available for common use cases: 1:1 (square), 4:3 (standard horizontal), 16:9 (widescreen), 9:16 (vertical mobile), 3:2 (DSLR photo standard), and others. The crop preview updates in real time as you adjust the selection. After cropping, download the result as JPEG or PNG. All processing uses the HTML5 Canvas API and runs entirely in your browser, your images are never uploaded to any server.
Cropping is one of the most common image operations in both professional and everyday contexts. For web development, precise cropping to a specific aspect ratio is essential when images are displayed in fixed-ratio containers: a card with a 16:9 image slot will distort or clip any image that is not already in that ratio. For social media, each platform has specific optimal dimensions: Instagram Feed posts display best at 1:1 (1080x1080) or 4:5 (1080x1350), Stories and Reels at 9:16 (1080x1920), Twitter/X at approximately 16:9 (1200x675), LinkedIn at 1.91:1 (1200x628), and Facebook at 1.91:1 as well. Cropping to these ratios before uploading prevents the platform from auto-cropping in a way that may remove important elements. For portrait photography, the standard crop ratios are 4:5 (the traditional portrait orientation) and 2:3 (the 35mm film frame ratio, which is the default crop for most DSLR and mirrorless cameras). The rule of thirds is a useful guide when positioning the crop: place the subject's eyes or the main point of interest at the intersection of the grid lines that divide the frame into thirds horizontally and vertically. This crop tool overlays a rule-of-thirds grid on the selection area to assist with this.
