Free Social Media Resizer – Perfect Crops for Every Platform

Every social network has its own preferred image dimensions, and posting a photo that doesn't match means dealing with awkward crops, blurry stretching, or important parts of your image getting cut off entirely. Our Social Media Resizer eliminates the guesswork by providing the exact official pixel dimensions for every major platform, then letting you crop your photo to fit perfectly, all processed locally in your browser. Since this Social Media Resizer never uploads your images to a server, your content stays completely private during the entire resizing process.

Using the Social Media Resizer starts with uploading your photo through the drag-and-drop zone, after which you select your target platform from a row of quick-access buttons covering Instagram, Facebook, YouTube, X (formerly Twitter), and LinkedIn. Each platform reveals its own curated list of correctly sized formats specific to how that network actually displays images, rather than offering generic, one-size-fits-all dimensions that don't reflect real platform requirements.

What makes this Social Media Resizer genuinely useful is the depth of formats covered within each platform. For Instagram alone, you can choose between Square Posts, Portrait Posts, Story and Reel dimensions, and Landscape Posts, each using the network's current official pixel specifications. Facebook options include Shared Posts, Page Covers, Event Covers, and Profile Pictures, while YouTube covers Video Thumbnails, Channel Banners, and Profile Pictures. X and LinkedIn round things out with their own platform-specific formats for posts, header images, and company banners.

Once you select a format, the interactive crop box automatically locks to that exact aspect ratio, so as you drag and reposition the crop area, your image stays perfectly proportioned to the platform's requirements without any manual aspect ratio math. A live dimension badge confirms exactly which pixel size you're targeting, and a description box explains the format clearly, so you always know precisely what you're exporting before you download.

Once your crop looks right, choose between JPG for photographic content or PNG for graphics and text-heavy images, then click download to export at the exact official pixel dimensions for your chosen platform and format. Because this Social Media Resizer runs entirely through canvas-based processing in your browser, there's no signup, no watermarks, and no limit on how many images or platforms you can resize. It's a genuinely practical tool for social media managers, content creators, and small business owners who need consistently perfect crops across every network, completely free.
