Image Multiformat

Your files never leave your browser

SocialShrink adapts a single image to every format your social networks need. Upload a photo and generate optimized versions for Instagram (square, portrait, stories), TikTok, YouTube (thumbnail and Shorts), X, LinkedIn, and Pinterest, each cropped to the platform's exact dimensions and compressed to weigh as little as possible without visible quality loss. All processing happens in your browser via WebAssembly and the Canvas API: your image is never uploaded to any server.

How it works

  1. Upload your image
    Drag or select a photo in JPG, PNG, or WebP. It loads into your browser's memory without leaving your device.
  2. Choose the platforms
    Check the networks you need. Each has its exact aspect ratio and resolution (for example, 1080x1350 for Instagram's vertical feed).
  3. Adjust the crop
    Drag to reposition the crop in each format. The frame adapts to the destination's aspect ratio and never leaves empty bars.
  4. Download everything in a ZIP
    One click generates all versions, compressed and ready. You download a ZIP with each file named by platform and format.

Your privacy

Your images are processed entirely in your browser using WebAssembly and Canvas. No file leaves your device, there are no intermediate servers, and we store nothing. When you close the tab, not a trace remains. This is real local processing, not a marketing promise.
