Turn a photo, logo, or illustration into character-based text art with this image ASCII generator. The original image and converted output appear side by side. Adjust the character width and tones, then copy your result or download it as TXT or PNG. Conversion happens in your browser rather than on a remote image-processing server.
How to use the image ASCII generator
- Upload a JPG, PNG, or WebP image up to 10 MB, or choose the sample photo.
- Set the character width. Start at 80 columns; increase it for more detail.
- Choose Standard ASCII, Simple ASCII, or Unicode blocks.
- Adjust brightness and contrast. Try edge detection for outlines or invert tones for the opposite shading.
- Copy the text, download a TXT file, or save the rendered art as PNG.
The preview refreshes after an adjustment. The PNG uses the light or dark paper selected in the output preview. Changing paper color does not change the text characters; invert tones if you also want to reverse the shading.
ASCII art image converter settings
| Image | Starting width | Adjustments to try |
|---|---|---|
| Logo or silhouette | 40-80 characters | Simple character set; edge detection for outlines |
| Portrait with a plain background | 100-140 characters | Standard set; contrast +15 to +30 |
| Landscape photograph | 120-200 characters | Standard set; reduce width if the scene looks noisy |
| Small icon | 20-60 characters | Simple set; increase contrast |
These are starting points, not guarantees. Small details and busy backgrounds can disappear when an image is reduced to a grid of characters. Use the original preview to compare your adjustments.
How an image becomes ASCII text
The converter resizes the image to the chosen number of columns. Its row count uses the source aspect ratio with a correction for characters being taller than they are wide. Output has at least one row and is capped at 500 rows to keep unusually tall images manageable.
Transparent areas are composited onto white. Each pixel's average red, green, and blue value determines its character: dark areas use dense symbols such as @, while light areas use sparse symbols or spaces. Brightness, contrast, inversion, and Sobel edge detection are applied before that mapping.
Standard and Simple modes produce ASCII characters. Blocks mode uses Unicode shading characters, so it is text art but not strictly ASCII.
Copying ASCII art without losing alignment
Use a monospace font in a terminal, code editor, or README code block. Proportional fonts, collapsed spaces, and wrapped lines can change the appearance. A TXT download preserves the character grid, but the app opening it still needs a monospace font.
For Instagram or other places where you cannot control font and whitespace, share the PNG export instead of pasted text. Wide output may require horizontal scrolling in the preview; it is not cropped in the download.
Common image conversion problems
The output is too noisy
Try a simpler source image or lower character width. Increasing contrast can separate the subject from the background. Edge detection emphasizes outlines instead of photographic shading.
A transparent logo looks wrong
The converter uses a white background for transparent pixels. A white logo on transparency needs a contrasting background added to the source image before conversion.
The image is too light or too dark
Adjust brightness in small increments, then compare the preview. Invert tones swaps dense and sparse areas. Dark paper changes the display and PNG colors without changing the ASCII text itself.
Is this a text-to-ASCII banner generator?
No. This tool takes an image file, not typed words. Use the Big Text Generator for large copy-and-paste letters, or the Text Path Maker for text arranged along a path.
