ASCII art image effects turn a photo into a grid of characters or dots and draw it over a background you choose. Everything runs in your browser, so the image is never uploaded.
How it works
The tool samples your image in a grid and replaces each cell's brightness with a character from the selected ramp (symbols ordered from dark to bright). Recipes are presets for the same engine, so you pick a look first and then fine-tune resolution, characters, color, background, and export.
Recipes
Six presets to start from. Choosing one swaps the character set, blend mode, and background defaults together (your export format, quality, and scale are kept).
| Recipe | Look |
|---|---|
| Color photo overlay | Samples the source color and lays characters over the photo |
| Color ASCII | Colorful ASCII conversion on a solid background |
| Terminal | Green characters on black, terminal style |
| Matrix | Falling-rain look with 0/1 and katakana |
| Blocks | Shade characters for a mosaic / poster feel |
| Newspaper | Monochrome, printed-page texture |
Main controls
| Control | What it changes | Best use |
|---|---|---|
| Resolution (columns) | How many characters fit across the width | Fewer for large poster-style glyphs, more for fine detail |
| Character set | The symbol ramp used for conversion (standard, detailed, blocks, braille, binary, katakana, and more — 10 in total) | Match the texture you want |
| Color | Sample from the image or use a single color | Keep photo colors or unify with a theme color |
| Contrast / Density | How brightness maps and how much of the image gets characters | From subtle texture to full coverage |
| Invert brightness | Swaps characters between light and dark areas | Suit a dark or light background |
| Background mode | Blurred image, original image, solid color, or transparent | Match thumbnails, posters, or overlays |
| Overlay opacity | Strength of the character layer | Balance readability against the source image |
How to add an ASCII effect to an image
- Drop a PNG, JPG, or WebP image into the upload area.
- Choose a recipe such as Color photo overlay, Terminal, or Matrix.
- Adjust resolution, character set, color, contrast, density, background mode, and overlay opacity.
- Pick an export format (PNG / JPG / WebP), quality, and scale (1x–4x).
- Download the finished image.
Which export format should I choose?
| Format | Transparency | Best for | Notes |
|---|---|---|---|
| PNG | Yes | Sharp characters, UI images, transparent overlays | Larger files, highest edge clarity |
| JPG | No | Photo-style social images and smaller files | Quality slider controls compression |
| WebP | Yes | Web publishing with smaller files | Good balance of quality and size |
Example
Take a product photo, choose Color photo overlay, keep a blurred image background, set overlay opacity around 90%, and export as WebP for a web-ready creative that keeps the colors while adding a text texture. Switch to Matrix or Terminal for a social-ready mono or green ASCII look. </content>
