Image to ASCII Converter
Convert images into grayscale ASCII art text with customizable character width and optional brightness inversion.
Run tool
This online tool transforms standard pictures into text-based ASCII art using grayscale character shading. When you provide an image, the tool reads the visual content, scales it to your chosen width, and computes the proportional line height using a vertical correction factor. It translates pixel brightness across a ten-character shading ramp, placing darker characters in shadowy regions and lighter characters across highlights. You can customize the output width to match standard terminal windows, code comments, or text files. The default layout produces eighty characters per line, but you can adjust this value to fit compact consoles or broader visual displays. If you work with light text on dark backgrounds, activating the invert option reverses the character ramp so highlights and shadows render accurately in your terminal or editor. The generated output delivers plain text alongside the final width, computed height, and line count.
Instructions
- Select or upload your image file into the image input field.
- Set your target character width, or keep the default value of 80 columns.
- Check the invert box if you want to reverse character shading for dark background themes.
- Run the conversion to generate the text art.
- Copy the generated plain text or review the reported width, height, and line count.
Examples
- Convert a logo image using the default 80-character width to generate text art for source code comments or README documentation.
- Convert a high-contrast portrait with a width of 120 columns and the invert option selected for clear display on dark terminal themes.
FAQ
How does the tool calculate ASCII output height?
The height is derived from the source image aspect ratio, scaled with a 0.55 vertical adjustment factor to compensate for standard monospace character dimensions.
What happens if no image data is supplied?
The conversion process requires readable image data; leaving the input empty or supplying corrupted data results in an error message.
When should I turn on the invert option?
Enable invert when pasting the generated ASCII art onto dark backgrounds, such as terminal consoles or dark-mode code editors, so character density matches expected brightness.
