Three single-purpose tools we built for ourselves and kept around because they paid for their keep. No sign-up, no upload, runs in the tab you have open.
Drop an audio file, pick a style, export a deterministic MP4. 8 visualizations, full control over color, motion, and titles.
Paste an HTML composition, render an MP4. Powered by the playground.
Re-encode animated GIFs to lean, modern MP4 — preserving timing.
Frames to HH:MM:SS:FF and back. Supports drop-frame 29.97.
The tools are nice. The playground is where it gets serious.
