Resize and crop images to the perfect dimensions for Twitter, Facebook, LinkedIn, and YouTube. Choose from cover photos, profile pictures, post images, and video thumbnails.
A social media optimizer resizes and crops images to the exact dimensions required by major social media platforms including Twitter/X, Facebook, LinkedIn, and YouTube. Each platform has specific image size requirements for posts, cover photos, profile pictures, and thumbnails, and using the wrong dimensions results in blurry or awkwardly cropped images. Our browser-based tool uses the Canvas API to precisely resize images to each platform's specifications. All processing happens locally in your browser, so your images remain private and never leave your device.
We support Twitter/X, Facebook, LinkedIn, and YouTube. Each platform has multiple image types including posts, cover photos, profile pictures, and more.
Images are output as JPEG at 85% quality for optimal file size and quality. Profile pictures use PNG to preserve crisp edges.
Yes! After selecting a platform and format, you'll see a preview of how your image will be cropped and sized before downloading.
If your image is smaller than the target dimensions, it will be upscaled. For best results, start with an image that's at least as large as the target dimensions.
