Image to ASCII Art
Convert an image into copyable text-based ASCII artwork
Image to ASCII Art — what it does
Convert an image into text art by sampling its brightness and mapping each region to a character from a density ramp you choose. Set the character width, pick a character set, optionally invert brightness for dark backgrounds, and copy the result as plain text that renders anywhere a monospace font does.
When this tool helps
- Making a text banner or logo for a terminal, README or command-line tool.
- Producing an image-free representation for a plain-text email or a bulletin board post.
- Creating retro-styled artwork for a personal site or code comment.
How to use it
- Choose an image with clear contrast.
- Set the character width in columns.
- Pick a character set and invert brightness if needed.
- Process, then copy or download the ASCII art.
Accuracy, limits, and good practice
- High-contrast images with a clear silhouette convert far better than busy photographs — detail turns to noise at character resolution.
- Invert brightness when the art will sit on a dark terminal; the mapping that reads correctly on white reads inside-out on black.
- Characters are taller than they are wide, so the output looks vertically stretched unless the renderer's line height is tightened.
Frequently asked questions
What width should I use?
80 columns suits terminals and email, 100 to 150 gives more detail on a webpage. Wider output needs horizontal scrolling.
Does the character set matter?
A lot. A longer ramp gives more tonal steps and smoother gradients; a short set produces a starker, more graphic look.
Can I convert it back to an image?
Not from the text. Screenshot the rendered art if you need it as a picture.

圖片轉 ASCII 字元畫能做什麼
把圖片取樣亮度，再把每個區塊對應到你選定的字元密度階，藉此轉成文字畫。設定字元寬度、挑選字元集，必要時反轉亮度以配合深色背景，結果是純文字，任何支援等寬字型的地方都能顯示。
什麼時候用得上
- 為終端機、README 或命令列工具做文字橫幅或標誌。
- 為純文字郵件或論壇貼文，做出不需圖片的視覺呈現。
- 為個人網站或程式註解製作復古風格的圖案。
使用步驟
- 選擇對比清楚的圖片。
- 設定字元寬度（欄數）。
- 挑選字元集，必要時反轉亮度。
- 執行轉換，再複製或下載字元畫。
精確度、限制與實務建議
- 輪廓清楚、對比高的圖遠比細節繁雜的照片好轉——在字元解析度下，細節只會變成雜訊。
- 作品要放在深色終端機時請反轉亮度；在白底看起來正確的對應，在黑底會整個反過來。
- 字元高比寬大，除非把行高收緊，輸出看起來會被縱向拉長。
常見問題
寬度該設多少？
終端機與郵件用 80 欄，網頁上 100 到 150 欄細節更多。再寬就需要水平捲動。
字元集有差嗎？
差很多。階數多的字元集色調層次細、漸層平順；字元少則呈現更強烈的圖像感。
可以轉回圖片嗎？
文字本身無法還原。需要圖片時，請對渲染後的成果截圖。
