HEIC → ASCII

POST /api/image-heic-to-ascii

Convert an HEIC/HEIF (the iPhone capture format) to ASCII art. Configurable width, character ramp, invert mode. Plain text or coloured HTML output.

Decodes an HEIC/HEIF image and renders it as ASCII art — plain text or per-character coloured HTML. Same options and output formats as `image-png-to-ascii`. Inherits the same input limits as the other HEIC tools: maximum 5 megapixels, no tile-grid iPhone captures.
