ASCII art is what programmers used to decorate README files before emoji existed, what BBS users sent each other in the 1980s, and what every terminal devotee still loves to embed in commit messages and shell prompts. Our free online Image to ASCII converter turns any photo, logo, or illustration into a block of text characters that approximates the original image using nothing but printable ASCII. Drop in a JPG or PNG, pick a width (in characters, not pixels — typical values range from 60 for a small avatar to 200 for a full poster), choose your character ramp (the sequence from light to dark, e.g. ` .:-=+*#%@`), and the converter samples the image and replaces each cell with the character whose visual density most closely matches the brightness of that region. Adjust the contrast to push midtones toward black or white, or invert the ramp for a light-on-dark terminal aesthetic. The output is plain text that pastes into anything: a README file on GitHub, a `<pre>` block on a website, a terminal prompt, an email signature, or a code comment. Real-world uses: dropping a project logo into the top of a README so the GitHub page has personality, decorating a CLI tool's `--help` output with a small banner, generating an ASCII version of your face for a retro profile picture, or creating decorative dividers for documentation. Everything happens in the browser; no upload, no signup. After generating, the [Word Count](/tools/word-count) tool can verify the result fits inside any character limits, and the [Code Beautifier](/tools/code-beautifier) is the right place to format the surrounding code if you are embedding the ASCII inside a multi-line string.

How to Use Image to ASCII

Upload an Image

Drop a JPG or PNG into the page. High-contrast images with clear shapes (logos, portraits, simple scenes) produce the best ASCII results.

Set the Width and Ramp

Choose how many characters wide the output should be. 80 columns is a classic terminal width; 120–200 gives more detail.

Tweak Contrast and Inversion

Slide contrast to push the result toward stark black-and-white. Invert the ramp for a light-on-dark terminal style.

Copy or Download

The text output appears in a monospace box ready to copy. Paste into a README, code comment, or terminal banner.

Features

Custom Character Ramps

Use the default density ramp or define your own — from minimal `.#` two-character ramps to elaborate 70-character custom sets.

Adjustable Width

Pick anywhere from 40 to 300 characters wide. Wider means more detail but a longer copy-paste.

Contrast and Invert Controls

Push midtones around to bring out shapes, or flip the entire ramp for terminal-friendly light-on-dark output.

Plain Text Output

The result is pure ASCII (or extended Unicode if you choose), which pastes cleanly into READMEs, code, emails, and comments.

Frequently Asked Questions

High-contrast images with clear shapes — logos, silhouettes, portraits with even lighting, simple scenes. Photos with subtle gradients and busy backgrounds turn into noise. If your image looks hard to read at thumbnail size, it will be hard to read as ASCII too.

Monospace characters are taller than they are wide (typically 1:2 aspect ratio), so an output that is 100 characters wide actually looks roughly 50 "pixels" wide visually. The converter compensates by sampling the image vertically at half the rate.

Yes — switch the ramp to use Unicode block elements (▁▂▃▄▅▆▇█) for finer-grained brightness levels. The result is no longer pure ASCII but renders beautifully in any monospace font.

Only if the editor uses a monospace font. In a proportional font, the spacing collapses and the image becomes unreadable. Always wrap ASCII art in `<pre>` tags on websites or use code fences in Markdown.

Yes — set the width up to 300 characters. The result is large but still pastes into any text file. For genuine print posters you would want to use vector tools instead.

Transparent areas are treated as the background colour (white by default), which usually maps to a space character. To handle transparency more cleverly, flatten the image against a black background first.
