halfsize compresses a video to an exact target size — 20 MB for Discord or WeChat, 16 MB for WhatsApp, 20–25 MB for email — then reports the measured VMAF and SSIM quality loss. It computes the bitrate budget, downscales when 720p beats a starved 1080p, and encodes in two passes. Runs fully locally on FFmpeg: no upload, no account, no quota, no watermark. Free, MIT licensed, with a local web UI, batch mode and JSON output.

Could you build this?
Yes It wraps ffmpeg for two-pass encoding at a target bitrate and uses libvmaf for quality metrics, all of which run locally with well-documented tooling.
