Image to ASCII Art
Turn any image into ASCII art. Pick a character set (standard, blocks or minimal), set the output width (40-200 chars), invert brightness, or render in colour using each pixel's original RGB. Copy the result or download it as a .txt file.

How to use
- 1
Upload an image
Drag and drop a JPG, PNG, WebP, BMP or GIF. The image is downscaled to your chosen width before conversion — even large photos work fine.
- 2
Pick a character set
Standard (10 chars, most detail), blocks (5 chars, chunky terminal look) or minimal (4 chars, very low-fi).
- 3
Adjust width, invert and colour
Set the output width (40-200 characters). Toggle invert to swap dark and light, or toggle colour to render each character in the pixel's original RGB.
- 4
Copy or download
Copy the ASCII art to your clipboard, or download it as a .txt file. Paste anywhere that accepts monospace text.
Common use cases
- Generate a unique text-based avatar for terminal or chat.
- Embed a low-fi preview of an image in code comments or README files.
- Create retro-styled banners for blogs or social posts.
- Visualise the brightness structure of an image at a glance.
Limitations
- ASCII art assumes a monospace font with characters about twice as tall as they are wide. We correct for this by scaling height by 0.55, but pasting into a variable-width font will distort the image.
- Colour mode requires a viewer that supports HTML/CSS colours — .txt downloads are plain text only.
- Very fine detail is lost at narrow widths (under 60 chars).
- Animated GIFs use only the first frame.
