How to convert IMAGE to ASCII
ASCII art converts an image into a grid of text characters where darker areas use dense characters like @ and # and lighter areas use sparse characters like . and space. The result is a text-based representation of the image that can be pasted into emails, code comments, terminal output, or README files. It is a classic technique from the early days of computing that remains popular for creative and nostalgic projects.

Frequently asked questions
Which images produce the best ASCII art?
High-contrast images with a clear subject against a plain background work best. Portraits, logos, and silhouettes tend to produce recognizable results. Busy scenes with many small elements are harder to read at ASCII scale.
Can I control the output size?
Yes. The width of the ASCII output in characters can be adjusted. Wider output preserves more detail but requires more horizontal space to display correctly.
Is there a limit on image size?
The conversion runs in your browser, so there is no server-side size limit. Very large images may be slow to process depending on your device.
What character sets are used?
The converter uses a standard density gradient: @#S%?*+;:,. where @ is darkest and space is lightest. This maps naturally to most fixed-width fonts.
Are my images kept private?
Yes. The entire conversion runs in your browser using WebAssembly. Your image is never uploaded to any server.
