How do I convert an image to ASCII art?

Open the Image to ASCII page in img-tools, then drag and drop, paste, or browse to load a JPEG, PNG, WebP, or AVIF photo. Pick the output width in columns and toggle Invert for light-on-dark shading; the ASCII text updates instantly. Copy the result to your clipboard or download it as a .txt file. It is free and runs entirely in your browser with no upload.

Are images uploaded to a server?

No. The conversion runs entirely in your browser; your image never leaves your device.

The image is downscaled to a grid of characters; each cell’s brightness is mapped to a character from a dark-to-light ramp.

Can I change the size?

Yes — choose the width in columns (60–160). More columns means more detail and a larger result.

Invert swaps dark and light, which looks better when you will display the art as light text on a dark background.

Is converting an image to ASCII art free?

Yes — turning your photo into ASCII text art is completely free, forever, with no account or sign-up required. You can convert as many images as you want with no usage limits. Your images are never sent to any server; the conversion runs entirely in your browser.

Does it work offline?

Yes. Everything runs locally with browser APIs and needs no server connection.

What formats are supported?

JPEG, PNG, WebP, and AVIF input. Output is plain text (copy or .txt).

ASCII art represents an image using printable characters, mapping pixel brightness to glyphs of varying visual density.
Monospace characters are roughly twice as tall as they are wide, so converters squash the row count (~50%) to keep the art proportional.
Relative luminance (Rec. 601: 0.299R + 0.587G + 0.114B) is a standard way to convert colour to perceived brightness.
Converting locally keeps the image on your device — no upload, and it works offline.
Downscaling on a canvas with high-quality smoothing averages each block of pixels before it is mapped to a character.
