Image to ASCII art: keep the subject readable
Convert a local image to a monochrome text preview, choose a sensible character width and preserve alignment when copying.

Use a simple source image
High-contrast shapes and a clear subject usually survive conversion better than a crowded scene. ASCII art replaces image brightness with text characters; it does not preserve colour, fine texture or accurate facial detail. The converter below processes a supported local image in the browser and produces plain text. Start with a small non-sensitive picture and keep the original.
Choose width before detail
More columns create a larger text result, but may wrap in the destination app. Try 60 or 80 columns first. The converter samples a shorter number of character rows because most monospaced characters are taller than they are wide. That correction is approximate and depends on the font. A different destination font may stretch the subject vertically.
Keep the spacing intact
Copy the output into a monospaced text block or code block. Proportional fonts and collapsed spaces break the alignment. Avoid a messaging field that automatically wraps at a narrow width. If the result looks inverted against a dark background, use the inverse option or change the destination colours. Check the complete block after pasting, not only in the preview here.
Recognize the limits
This is a luminance-based image conversion, not a text-banner font generator or a reconstruction of hidden detail. Very large files are rejected to protect browser memory. Transparency is composited on white before sampling. The output is decorative; screen readers will read characters rather than infer the picture, so provide an ordinary text description wherever the image’s meaning matters.
