ASCII Art Maker

JPG, PNG and WebP up to 20 MiB, 8 million pixels and 16,000 pixels per edge. Transparency is composited with your chosen source matte before brightness is sampled. Animated images use a decoded frame; this is not an animated ASCII exporter.

Use a monospace font and preserve spaces and line breaks. Proportional fonts and apps that collapse whitespace distort character art. TXT preserves the complete grid; PNG preserves the rendered image appearance.

Columns set horizontal detail from 20 to 200. Rows follow the source dimensions and character width-to-height ratio, capped at 180. The default ratio 0.5 matches the 10 by 20 pixel PNG character cells. Tall sources may compress at the row cap; crop them first.

No. It draws your message using a device sans-serif, serif or monospace font, then samples that image into ASCII. Up to 100 Unicode characters across five lines are supported. Very long lines are fitted to a bounded canvas and may need more columns.

Enter 2–40 different printable ASCII characters, darkest first and lightest last. A space at the light end gives an open background. Glyph darkness varies by font, so a custom ramp may need experimentation.

It distributes brightness quantization errors to neighboring cells with Floyd–Steinberg error diffusion. This can represent smooth shading with fewer characters but may look noisier.

No. They affect character selection. Colored PNG ink comes from the sampled image after transparency compositing. Turn off source colors to use your chosen monochrome ink; the PNG background is separate from the source matte.

Both use the same current character grid. TXT contains characters, spaces and line breaks without colors. PNG draws the grid with source or monochrome ink and a background, so it retains that rendering when shared.
