Reverse a video in your browser
Filzy lets you reverse a video to play a video backwards from end to start, useful for creative effects and meme clips. 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 with all frames played in reverse order, audio reversed too unless you remove it first. 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.
