Aspect Ratio Cropper

Crop images to precise aspect ratios with locked proportions, ensuring your output matches specific format requirements exactly. Select from common ratios—16:9 (video/widescreen), 4:3 (traditional displays), 1:1 (square), 4:5 (Instagram portrait), 3:2 (standard photos), 2:3 (vertical prints), 21:9 (ultrawide)—or enter custom ratios for specialized needs.

With the aspect ratio locked, you can freely resize and reposition your crop area while proportions remain perfectly constrained. The selection scales uniformly: drag any edge or corner and both dimensions adjust together to maintain the ratio. Position the locked selection over the most important part of your image to ensure the best possible crop within your required proportions.

Social media managers preparing platform-specific content crop images to each network's optimal ratios—square for Instagram grid posts, 4:5 for Instagram portrait, 16:9 for YouTube thumbnails. Video producers extracting still frames at specific aspect ratios maintain consistency with their video format. Print designers cropping images for standard frame sizes ensure photos fit common mat and frame proportions. Web developers preparing images for fixed-ratio containers produce properly-proportioned content that won't require CSS cropping. E-commerce teams standardizing product imagery across catalogs ensure consistent proportions throughout their visual catalog. Anyone working with layouts or platforms that expect specific aspect ratios will find ratio-locked cropping essential for producing properly-proportioned content.
