An image to ASCII art converter turns a photo or graphic into text by matching each sampled area to a character with a similar visual density. This browser tool lets you tune detail, contrast and character style, then copy or download the result without uploading the original image. The converter uses your browser's Canvas API to resize and sample the image. It applies perceptual luminance weighting, corrects for the tall shape of monospace characters, and maps each sample onto the chosen density ramp. Processing stays on your device. ## How to use it 1. **Add an image** - Drop in or choose a PNG, JPG or WebP file, or load the built-in example. 2. **Tune the conversion** - Choose an output width and character set, then adjust contrast, brightness or inversion while the result updates. 3. **Use the result** - Copy the ASCII art to your clipboard or download it as a plain-text file. ## Who it's for - **Developers and open-source maintainers** can make compact artwork for READMEs, terminal banners and source comments. - **Chat and community users** can turn a recognizable photo or logo into copyable plain text for Discord and forums. - **Designers and hobbyists** can explore retro terminal aesthetics before refining the result in a text editor. - **Teachers and students** can see how luminance quantization represents an image with a limited symbol palette. ## Expert note Monospace glyphs are usually about twice as tall as they are wide, so the converter halves the sampled row count; omitting that correction makes faces and circles look vertically stretched. ## Frequently asked questions ### Is my image uploaded? No. The browser decodes, resizes and samples your image locally with Canvas. The file and generated ASCII text are not sent to CanDoYa or stored on a server. ### Is the image to ASCII art converter free? Yes. You can convert images, change every available setting, copy the output and download a TXT file without signing up or paying. ### What image limits apply? The converter accepts one PNG, JPG or WebP file up to 25 MB, with no side longer than 16,384 pixels and no more than 50 megapixels. Output width ranges from 20 to 200 characters. ### How does image to ASCII conversion work? The image is resized to a small grid, each cell is reduced to a perceptually weighted brightness value, and that value selects a character from light to dense. Contrast and brightness are applied before the character is chosen. ### Why does my ASCII art look too dark or flat? Photos with a narrow tonal range often map to only a few similar characters. Raise the contrast, adjust brightness, try the detailed character set, or invert the mapping when placing the result on a dark background. ### Can I use the ASCII art in Discord or a README? Yes. Copy the output and paste it inside a code block so a monospace font preserves alignment. For narrow chats, reduce the output width before copying. ### Does the converter work offline? After the page has loaded, conversion uses built-in browser features and does not require an upload. The resulting text can be copied or downloaded directly from your device. ## Related tools - [Grayscale Converter](https://candoya.com/tools/grayscale-converter/) - [Pixelate Image](https://candoya.com/tools/pixelate-image/) - [Image Resizer](https://candoya.com/tools/image-resizer/) - [Image Color Palette Extractor](https://candoya.com/tools/image-color-palette-extractor/) - [Dominant Color Finder](https://candoya.com/tools/dominant-color-finder/) --- *Markdown edition of , published for AI agents and other automated readers.
