About Video Optimizer

Video Optimizer compresses videos right in Chrome — privately, on your device. Drop in a video, pick a quality preset, and download a smaller file. No uploads, no accounts, no waiting on a server. Best for Short clips, screen recordings, and videos you need to shrink before sharing Typical files in the tens to low hundreds of MB Anyone who wants compression without sending footage to the cloud Works with Input: MP4, MOV, WebM, MKV, AVI, and more Output: MP4 or WebM Quality presets and optional downscale (1080p / 720p / 480p) Features Local compression in the browser (files stay on your device) Chrome Side Panel — stays open as you switch tabs Quality presets: light, balanced, strong, and tiny Optional downscale to 1080p, 720p, or 480p Cancel compression anytime Fallback mode for tricky files (including some HEVC screen recordings) UI follows your Chrome language How to use Click the Video Optimizer icon Drop or choose a video in the side panel Select format, resolution, and preset Compress and download Ideal when you need to shrink a clip for email, messaging, or the web — without sending it anywhere. Processing: runs locally with FFmpeg.wasm in Chrome. That means strong privacy and zero backend — and also means it’s built for convenience, not as a replacement for desktop tools like HandBrake on huge 4K or multi‑GB files. Soft limit: up to 512 MB per file. Changelog 1.1.0 • Aspect ratio options: original, 16:9, 9:16, 1:1, 4:5 • Quality presets are now a slider with short descriptions • Open the compressed preview in a new tab • More compact file card and settings layout in the side panel 1.0.0 - Initial release
