How it works
- 1
Upload a video file from your device.
- 2
Each frame is sampled and mapped to characters based on brightness.
- 3
Preview the ASCII-art playback directly on the page.
- 4
Play through the converted frames or grab the output for your own use.
Turn ordinary video into retro ASCII art
ASCII-art video has a distinctive terminal aesthetic that's popular for creative projects, retro-style demos, and social clips. This tool automates the frame-by-frame brightness sampling that used to require a script, converting an uploaded video straight into playable ASCII frames.
All the frame analysis happens on your machine
Because decoding and sampling run in the browser rather than on a remote render farm, there's no waiting in an upload queue and no video content passing through a third-party server. The conversion speed depends only on your own device.
Frequently asked questions
Is my video uploaded to a server for the conversion?
No, the video is decoded and each frame is analyzed directly in your browser to build the ASCII output. Your file is never sent anywhere for processing.
What determines which character is used for each part of the frame?
Each region of a frame is sampled for brightness, and darker or lighter areas are mapped to different characters from a fixed density ramp, which is how classic ASCII-art renderers simulate shading with plain text.
Does it work with any video format?
It works with common web-playable formats like MP4 and WebM, since the browser's native video decoding is used to read frames. An unsupported codec simply won't play back for conversion.
Will longer or higher-resolution videos take longer to convert?
Yes, since every frame is sampled pixel by pixel in the browser, longer clips and higher source resolutions mean more frames and more per-frame sampling work, which takes proportionally longer on your device.
Can I adjust the resolution of the ASCII output?
The output resolution is tied to how densely each frame is sampled into characters - coarser sampling gives a chunkier, more abstract look, while finer sampling preserves more detail at the cost of a larger character grid.
