Glyphtrix

Local · In-browser · Open source

Turn pixels into glyphs - images & video to ASCII art.

Glyphtrix renders ASCII visual art entirely on your device. Fine-tune density, characters, colors, and fonts, then export as PNG, text, or a frame sequence.

Capabilities

Everything you need to dial in the look

Images & video

Drop in stills or clips. Example assets and presets help you explore fast.

Live adjustments

Brightness, contrast, and more with a preview that updates as you tweak.

Deep customization

Character sets across languages and Unicode, fonts, palettes, spacing, density, and scale.

Exports

PNG snapshots, plain text, or ZIP sequences for video frames.

Privacy

Your files stay on your machine

Processing runs in the browser. Nothing is uploaded for conversion. Media lives temporarily as blobs until you close or refresh - ideal for experimenting without sending assets to a server.

At a glance

  • No cloud rendering pipeline
  • No install required - optional offline bundle via static files
  • Open codebase you can inspect and fork

How it works

From canvas pixels to characters

Glyphtrix reads the image on a canvas, applies your adjustments, divides the frame into a grid sized by Density, maps each cell’s brightness to a character from your set, then paints those glyphs with your chosen colors and font - giving you printable ASCII art or a stylized terminal aesthetic.
