How is an image turned into ASCII art?
The tool reads each pixel in the image, calculates its brightness, and maps that brightness to a character from a ramp like @ % # asterisk plus colon dot space, where dense characters represent dark areas and sparse characters represent light areas. The result is a grid of characters that resembles the original picture when viewed from a distance. You can pick different character ramps to favour soft tones or stark contrast depending on the look you want.
How do I control the resolution of the ASCII output?
Use the resolution slider to set how many characters wide the output should be, from a tiny 40 column thumbnail up to a detailed 300 column version. Higher resolutions capture more detail but produce a much wider block of text. Keep the value matched to where you plan to display the result, for example narrower for a chat message and wider for a printed banner. The aspect ratio of the original image is preserved automatically based on the chosen width.
Can I generate coloured ASCII art instead of plain black and white?
Yes. Switch the colour mode on and each character is tinted with the colour of the underlying pixel. The result is exported as HTML or PNG, since plain text cannot store colour information. Black and white mode produces a string that you can paste anywhere, including a tweet or a code comment. Coloured output is great for sharing on websites or as a desktop wallpaper, where the extra information makes the picture much more recognisable.
Why does my ASCII art look stretched vertically?
Most fixed width fonts are taller than they are wide, so a square pixel mapped to a single character produces an output that looks taller than the original. The tool corrects this by sampling roughly two pixels per character vertically by default, but you can fine tune the ratio in the settings if your font has unusual proportions. If the output still looks wrong when pasted somewhere, switch the destination to a font like Consolas or Menlo where the ratio is well known.
What kinds of images work best for ASCII conversion?
High contrast images with a clear subject convert most cleanly, because the algorithm relies on differences in brightness to pick characters. Portraits, silhouettes and logos tend to look great. Photos with a lot of subtle detail, like landscapes with thin branches, can come out muddy at low resolutions. If a picture looks weak in ASCII, increase the contrast first using the image filters tool, or raise the output resolution to give the algorithm more characters to work with.
How do I save or share my ASCII art?
You can copy the text to the clipboard with one click, download it as a TXT file, or export it as a PNG that bakes the text into an image. The PNG is the safest option for sharing on social media, since some platforms remove or reflow plain text and break the alignment. There is also a copy as HTML option that includes inline colour styles, ready to embed in a blog post or online portfolio.
