Question 1

How does the Image to ASCII converter work?

Accepted Answer

The tool resizes the image to a fixed character width, then for each cell it samples the average pixel brightness and maps it to a character from the chosen charset (dense, simple, blocks or binary). The result is a faithful black-and-white text rendering you can copy or download.

Question 2

Is my image uploaded to a server?

Accepted Answer

No. The image is processed entirely in your browser using the Canvas API. Nothing is uploaded — open DevTools network tab to verify, no requests are made for image data.

Question 3

What image formats are supported?

Accepted Answer

Any format your browser can decode: PNG, JPG, WebP, GIF, BMP, AVIF and SVG. Just drag-and-drop or click to upload.

Question 4

How do I get the best result?

Accepted Answer

For portraits or high-contrast art, use a width of 80-120 and the dense character set. For logos and line art, the simple or block sets work better. Increasing the contrast slider helps noisy photos.
