Textmode Overlay

Turn <canvas> and <video> elements into live ASCII art.

Click the extension, pick a canvas or video, and a live ASCII/textmode layer appears directly on top of the original media - aligned, adjustable, exportable, and removable at any time. Built with textmode.js. ─── HOW IT WORKS 1 Click the [Textmode Overlay] icon in your toolbar 2 Click "select media" in the overlay panel 3 Hover any visible canvas or video element 4 Click the element to create the overlay 5 Adjust settings, export, remove it, or replace the selected media anytime ─── OVERLAY CONTROLS ▸ overlay show or pause the overlay ▸ opacity blend the overlay with the original ▸ font size control character density (1-64 px) ▸ invert swap character and cell colors ▸ character color sample from the source or use a fixed color ▸ cell color sample from the source or use a fixed color ▸ glyph ramp choose the characters used for shading ▸ font choose from bundled textmode fonts ─── EXPORT OPTIONS ▸ TXT plain-text character grid ▸ SVG scalable vector snapshot ▸ PNG raster image export ▸ JPG compressed raster export ─── PRIVACY & PERMISSIONS Textmode Overlay runs only after you click it. It works on the active tab, keeps processing local in your browser, and does not collect data.

The extension will show a clear message when this happens.
