What is an ASCII art generator?
ASCII Art Generator is an online tool that converts regular images into artistic images composed of characters. It scans the brightness and color of an image’s pixels and uses characters of varying densities (such as @%#*+=-:. ) to recreate the image’s contours and gradations, generating unique works of text art.
💡 All processing is done locally in the browser; images are not uploaded to any server, so please feel free to use this service.
Features
- Multiple character sets: Classic ASCII, high-density, block characters, dot-matrix characters, numerals, and Chinese stroke characters—6 styles
- Image Adjustment: Brightness / Contrast / Gamma Correction, to make the outlines of the character art clearer
- Dithering Enhancement: Floyd-Steinberg Error Diffusion Algorithm, which preserves detail even at low bit depths
- Color Output: Preserves the original image's colors and generates HTML or SVG with color styling
- Multiple Export Options: Plain text (TXT), color HTML, and vector SVG; copy or download with a single click
- Batch Processing: Convert multiple images at once and download them as a package
- Preset Styles: Balanced Details, Display, Poster Style, Clean Outlines—Switch with a single click
- Custom Character Sets: Enter your own symbol sequences to create unique visual effects
