Rotate a video in your browser
Filzy lets you rotate a video to fix the orientation of a video shot in the wrong rotation, typically a phone clip recorded in portrait shown sideways. The tool runs ffmpeg.wasm directly inside your browser tab, so your video file is decoded and re-encoded on your CPU without ever uploading to a server. The output is an MP4 rotated 90, 180 or 270 degrees, with the metadata fix baked into the actual frames so every player handles it correctly. Filzy supports MP4, MOV, WebM as input. The free tier processes 3 files without an account; signing up unlocks unlimited use, with no daily cap and no watermark.
Files stay on your device
Decoding, processing, and re-encoding all happen in a Web Worker via ffmpeg.wasm. The video bytes never reach a server, no temporary copy is stored anywhere.
Local CPU speed
WebAssembly delivers near-native performance on your CPU. A 5-minute clip typically processes in 1 to 3 minutes on a modern laptop, depending on the operation.
No upload, no daily cap
Skip the multi-minute upload that plagues server-based tools. The bottleneck moves to your CPU, where you have full control. No daily limit, no watermark.

Filzy rotates the video locally
ffmpeg.wasm decodes the video, applies the operation, and writes the result. Progress is shown frame by frame in the browser. The output is an MP4 rotated 90, 180 or 270 degrees, with the metadata fix baked into the actual frames so every player handles it correctly.
