Optimize Video — Compress, Resize, Trim
Every platform has an opinion about your video: email wants it under 25 MB, socials want the right pixels, attention spans want it shorter. The optimize family reshapes what you already have — smaller files via smart re-encoding with a bitrate cap that guarantees output never grows, exact widths for embeds, lossless trims that cut without re-encoding. All of it runs on your device: your footage never touches a server, and on supported browsers the heavy lifting rides your hardware encoder.
Which tool do I need?
| You need to… | Use | What you get |
|---|---|---|
| Fit an email or chat size limit | Compress | Much smaller MP4; bitrate capped below source so it never grows |
| Hit an exact width (embeds, platforms) | Resize | 1080 px wide MP4, aspect kept |
| Keep only a section, lose nothing | Trim | Lossless stream-copy cut (keyframe-snapped) |
| Change the shape for vertical/square feeds | Crop | Center-cropped 9:16, 1:1, 4:3 or 16:9 |
