VidSizer is a free, open-source video compressor that shrinks any video to an exact target size — like 25MB for Discord or 16MB for WhatsApp — entirely in your browser with FFmpeg.wasm. No uploads, no signup, no watermark. I built it because every “compress to X MB” tool I tried either re-encoded blindly or sent my files to a server.
