How to convert an image to ASCII art

Short answer

An ASCII art generator maps each part of the image to a character based on its brightness — dense characters for dark areas, light ones for bright areas. Upload an image, adjust the width, and copy the text output.

How image-to-ASCII works

The image is divided into a grid, and each cell's brightness is matched to a character from a ramp — for example .:-=+*#%@ from light to dark. Reading the characters back at a distance re-forms the picture out of text.

Convert an image

Add the imageDrop in a photo, logo, or icon. It decodes locally.
Set the widthMore characters mean more detail but a larger block of text.
Copy the ASCIIPaste it into a comment, README, terminal, or chat.

High-contrast images work bestASCII art relies on brightness differences, so bold, high-contrast images with a clear subject convert best. Busy photos with subtle tones turn into noise.

Tips for a clean result

Crop to the subject first so detail is not wasted on the background
Use a monospace font when displaying the output, or it will distort
Increase the width for more detail, decrease it for compact art
Simple logos and portraits read better than cluttered scenes

Questions

Why does my ASCII art look distorted?

ASCII art must be displayed in a monospace font so every character takes the same width. In a proportional font the columns misalign and the image warps.

What images convert best to ASCII?

High-contrast images with a clear subject — logos, silhouettes, and portraits — convert best. Low-contrast or highly detailed photos lose their shape in the character grid.

Do these tools upload my images?

No. Utilumo's image tools decode, edit, and export pictures inside the browser tab. The files are never uploaded or stored on a server.
