Image to ASCII Art Converter

How to convert an image to ASCII art

1. Drop an image onto the drop zone or click to choose one from your device.
2. Drag the width slider to choose how many characters wide the art should be (40–200).
3. Toggle "Invert brightness" if the result looks like a photo negative, or "Color mode" to render each character in its sampled color.
4. Click "Convert to ASCII" to generate the art, then copy the text or download it as a .txt file.

Why use ZillaKit's Image to ASCII Art Converter?

ASCII art turns a picture into text made entirely of ordinary characters, which makes it perfect for retro terminal art, forum signatures, README banners, code comments, and social posts with a nostalgic computing feel. ZillaKit samples the grayscale brightness of your image on an HTML canvas and maps each region to a character from a shaded ramp, from dense symbols like @ and % for dark areas down to a plain space for the brightest. Everything happens locally in your browser using canvas pixel data — your photo is never uploaded to a server, so it stays private the entire time. The width slider lets you trade detail for size, the invert toggle flips light and dark for images that read better as a negative, and color mode wraps each character in an HTML span with its sampled color so you can paste colorful ASCII directly into a web page. It's free, requires no signup, and works entirely offline once the page is loaded.

FAQ

What image formats are supported?

JPG, PNG and WebP images all work. The image is decoded locally in your browser and never uploaded anywhere.

Why does my ASCII art look inverted?

Different monospace fonts and terminal themes (light vs dark background) can make brighter areas look darker or vice versa. Use the "Invert brightness" toggle to flip the mapping until it looks right for your display.

What does color mode do?

Color mode wraps each character in an HTML span colored to match the pixel it represents, so when pasted into a web page or rich-text editor the ASCII art keeps a tinted, photo-like appearance instead of being plain gray text.

Can I use the result outside a monospace font?

ASCII art relies on every character occupying the same width, so it will only look correct in a monospace font such as Consolas, Courier New, or a code block on forums and messaging apps.

Is there a limit on image size?

No hard limit, but very large images are automatically downsampled to your chosen character width before conversion, so processing stays fast regardless of the original resolution.
