Crop and resize images to specific aspect ratios like 16:9, 4:3, 1:1, 9:16, and more. Upload any image, select your desired ratio, preview the result, and download the cropped version. Perfect for social media posts, thumbnails, and profile pictures. Everything runs in your browser — no data is uploaded to any server.
Resizing images while maintaining or changing aspect ratios is a daily task for content creators, web developers, and social media managers. Each platform has optimal dimensions — a landscape photo needs different crops for Instagram feed, Pinterest pins, and Twitter headers. This tool calculates the exact pixel dimensions needed when converting between aspect ratios, showing you whether content will be cropped or padded. It handles common presets (16:9 for video, 1:1 for social, 4:5 for Instagram portrait) and custom ratios for specialized needs. Understanding the math behind aspect ratio conversions prevents distorted images and ensures your content looks professional across all platforms.
This tool only calculates dimensions — it doesn't modify your image. When you apply these dimensions in an image editor, upscaling (making larger) reduces quality while downscaling (making smaller) is generally safe.
Center-crop works for most content. For photos with subjects off-center, use your editor's focal point or rule-of-thirds alignment. Always preview crops before exporting.
Instagram: 1080×1350 (4:5), Twitter: 1200×675 (16:9), Facebook: 1200×630, Pinterest: 1000×1500 (2:3), LinkedIn: 1200×627. This tool helps convert between all of these.
Match your export ratio to your target platform (16:9 for YouTube, 9:16 for TikTok). If source footage has a different ratio, choose between cropping (losing edges) or padding (adding bars).
Letterboxing adds horizontal black bars (top/bottom) when wide content plays on a taller screen. Pillarboxing adds vertical bars (left/right) when narrow content plays on a wider screen.
