ASCII 字元畫生成器：圖片轉字元畫

上傳一張照片、頭像或 Logo，它會把畫面的明暗換成一行行字元，可以直接複製貼上，也可以下載儲存。這裡用的是固定演算法，不是 AI：同一張圖、同樣的設定，每次結果都一樣。登入後免費使用。

登入後免費使用。無需 AI 模型。

用 AI 根據文字描述生成字元畫先讓 AI 根據描述生成原圖，再轉換為文字和 PNG。

選擇圖片

PNG、JPEG 或 WebP · 最大 5 MB

僅在點選生成或轉換時，按所選模型或轉換的限制縮放並傳送圖片，原圖預覽保持不變。請使用你有權編輯的圖片。

圖片按比例縮小，最長邊不超過 512 像素。透明區域轉為白色。

效果設定

相同圖片和設定，得到相同效果。調整後點選「轉換圖片」套用。

怎樣把圖片轉成字元畫

登入後上傳圖片，設好寬度，再複製或下載字元網格。

  1. 上傳圖片

    登入後選擇不超過 5 MB 的 PNG、JPEG 或 WebP，也可以先用範例圖試試。

  2. 設定寬度

    選擇每行字元數（24 到 85），如果字元畫要放在淺色背景上，可以開啟「反轉明暗」，然後點選「轉換圖片」。

  3. 儲存結果

    複製文字，或者下載 TXT 和 PNG。貼上時請使用等寬字型，並保留換行。

不管你想的是把圖片轉成字元，還是把圖片變成文字畫，都是下面這三步。

檢視轉換效果

照片轉字元畫

主體清楚、背景簡單的照片效果最好。人像、寵物、純色牆前的物品，轉完一般還認得出來；畫面太雜或者灰濛濛的照片，容易變成一片噪點。上傳前先把主體裁出來，往往比加每行字元數更管用。 圖片會先按比例縮小到最長邊不超過 512 像素，透明區域會變成白色。

圖片轉文字畫

文字畫、字元畫、ASCII art 說的是一回事：只用鍵盤字元拼出來的圖。每次轉換都會給你同一組字元的兩種形式：一份純文字，貼到支援等寬字型的地方就能用；一張版式完全相同的 PNG，用在會打亂字型的地方。工具只用 10 個字元——空格 . : - + = % * @ #——按筆畫多少對應不同亮度。

你會得到什麼：一份 TXT，一張 PNG

每次轉換都會給你同一組字元的兩種形式：一份可複製或下載的 TXT，一張版式完全相同的 PNG。

範例圖片轉換後的 ASCII 字元畫（PNG）

兩個關鍵設定

每行字元數

每行字元數越多，細節越多，每行也越長。放進 README 或聊天訊息時，先用少一點的每行字元數，避免自動換行。特別窄或特別高的圖片，實際每行字元數可能比設定的少，因為字元網格會跟著圖片比例走。

反轉明暗

預設是深色背景上的淺色字元，反轉後正好相反。要貼到淺色頁面上，兩種都試試。

貼上後不走樣

字元畫只有在等寬字型、空格和換行都保留的情況下才能對齊。在 GitHub README 裡用 ``` 程式碼區塊包起來；在終端裡關掉自動換行；在會改字型、吞空格的社群和聊天軟體裡，直接發 PNG。詳見在 GitHub README、X 和終端裡使用字元畫。

  • GitHub README / Markdown：放進 ``` 程式碼區塊裡。
  • 終端和編輯器：用等寬字型，關掉自動換行。
  • 社群平臺和聊天軟體：有些平臺會壓縮空格或換字型，拿不準就直接發 PNG。

關於這個工具

怎麼把圖片轉成 ASCII 字元畫？

登入後上傳不超過 5 MB 的 PNG、JPEG 或 WebP，設定每行字元數，點選轉換，即可複製文字或下載 TXT 和 PNG。

這個字元畫生成器免費嗎？

免費，登入即可使用。

需要註冊登入嗎？

需要。不登入可以瀏覽頁面，但轉換圖片需要登入。

貼上後字元畫為什麼錯亂？

目標位置多半用了非等寬字型或合併了空格。請放進程式碼區塊或等寬字型中，或直接分享 PNG。

什麼樣的照片效果最好？

主體清晰、對比度高、背景簡單的照片。低對比或紋理很細的照片容易變成噪點。

同一張圖每次結果一樣嗎？

一樣。這是固定演算法而非 AI，相同圖片和設定總是得到相同字元。
