About TwoThink Video

TwoThink Video is the video site of the TwoThink tool matrix. Compressing, trimming, converting to GIF, merging and vertical adaptation — the everyday jobs all run locally in your browser.

Operated by: 双思睿（天津）科技有限公司 (Shuangsirui (Tianjin) Technology Co., Ltd.)

How it processes: The current version uses a single-threaded FFmpeg WASM core (about 30MB), which is downloaded and cached in your browser on first use. Speed depends on the performance of your device.

WeChat users: The WeChat in-app browser cannot run the video processing properly. Tap the "…" in the top-right corner and choose "Open in browser", or copy the link into Safari / Chrome.

Recommended browsers: Chrome / Edge 100+, Safari 15+ and Firefox 100+. Older browsers such as IE are not supported.

Our brand promise: files are never uploaded · no sign-up · free forever · no pop-up ads.
