Video for Social

Your files never leave your browser

SocialShrink's video tool compresses and adapts your videos to the exact formats of each social network, right in your browser. Choose a destination (Instagram Reel, TikTok, YouTube Short, YouTube 16:9, or simply compress keeping the original ratio), adjust the crop if the format requires it, and download an optimized H.264 MP4 with the minimum weight for that platform. It processes using FFmpeg compiled to WebAssembly, without uploading your video to any server.

How it works

  1. Upload your video
    Drag or select an MP4, MOV, or WebM video. It loads in your browser — it's not uploaded anywhere.
  2. Choose the destination
    Select which network you need the video for: Instagram Reel/Story (9:16), TikTok (9:16), YouTube Short (9:16), square post (1:1), YouTube (16:9), or simply compress without changing the proportions.
  3. Adjust the crop
    If the destination format crops the video (e.g., from horizontal to vertical), drag to choose which part is shown. The crop respects the platform's exact ratio.
  4. Process and download
    The FFmpeg engine encodes the video to H.264 MP4 with AAC audio. You see real-time progress and can cancel at any moment. Then download the result or generate another format from the same video.

Your privacy

Your video is processed entirely in your browser using FFmpeg compiled to WebAssembly. It's the same professional engine used by production studios, but running on your device. Not a single frame of your video leaves your computer or phone. No servers, no cloud uploads, no risk to your content.
