How to crop an image online
This image cropper lets you select any rectangular region of your image and export just that portion. Upload your image, drag the crop handles to select the area you want to keep, and click Crop. You can use freeform selection or lock to a specific aspect ratio. The crop area shows a rule-of-thirds grid overlay to help with composition. All processing happens in your browser — your images are never uploaded to any server.
Aspect ratios and social media sizes
Different platforms require different image dimensions. Instagram posts work best at 1:1 (square) or 4:5 (portrait). YouTube thumbnails need 16:9 at 1280x720 pixels. Facebook covers use a wide 820x312 format. Twitter/X posts display best at 16:9 (1200x675). This tool includes one-click presets for all major social media platforms, so you can crop your images to the exact dimensions each platform expects without manual calculation.
Tips for effective image cropping
Use the rule of thirds grid to place key subjects at intersection points for visually appealing compositions. Crop tightly to remove distracting elements and draw focus to your subject. For product photos, leave consistent padding around the item. For profile pictures, center the face in the upper third. When cropping for web, consider that mobile users see smaller versions — simpler compositions with larger subjects work better across all screen sizes.
Frequently Asked Questions
Is my image uploaded to a server?
No. All cropping happens entirely in your browser using the HTML Canvas API. Your images never leave your device, making this tool safe for sensitive or proprietary photos.
Can I crop to a specific pixel size?
Yes. Enter exact width and height values in the size inputs. You can also lock to aspect ratios like 1:1, 4:3, 16:9, or use social media presets for platform-specific dimensions.
What output formats are available?
You can export as PNG (lossless, supports transparency), JPEG (smaller file size with adjustable quality), or WebP (modern format with best compression). Choose JPEG or WebP for photos, and PNG for images with text or transparency.
