A free GIF to PPM converter for Graphics Interchange Format files. Browser-based pairs here usually run in this tab, with no file upload.

把你的 GIF 檔案拖曳到這裡

or 瀏覽你的裝置 · 貼上快捷鍵 Ctrl+V

Accepts .gif files. You can queue several files; each is processed one after another on your own device.

你的檔案不會離開這台裝置——沒有上傳,也沒有伺服器可以刪除它們。

使用方式
  1. 01

    新增你的 GIF 檔案

    把檔案拖放到上方的方框,或點擊以瀏覽選取。檔案會直接從磁碟讀取——不會傳送到任何地方。

  2. 02

    檢查設定

    PPM is already selected. Open the gear icon on any row if you want to change quality, dimensions or codec before converting.

  3. 03

    下載你的 PPM

    按下轉換,等待該列完成即可。若轉換多個檔案,可以將它們一起打包成單一 ZIP 檔下載。

GIF

Graphics Interchange Format

每格畫面最多只有 256 色,技術上早已過時十多年,卻因為能在任何地方自動播放動畫而歷久不衰。若動畫長度超過幾秒,MP4 或 WebP 能以十分之一的體積呈現更好的畫質。

PPM

Portable Pixmap

刻意設計成最簡單的影像格式——一段簡短的文字標頭,後面接著原始像素數值。在學術界與 Unix 管線中備受喜愛,正是因為任何人都能用十行程式碼解析它。

轉換前值得了解的事
  • Both GIF and PPM store every sample exactly, so nothing here is re-compressed — only the container changes.
  • GIF 支援透明背景,而 PPM 不支援,因此原始檔中的任何透明部分,在轉換過程中都會被壓平為實色背景。

FAQ

關於 GIF 轉 PPM 的常見問題

這個 GIF 轉 PPM 轉換器是免費的嗎?

是的。在這裡把 GIF 轉換為 PPM 完全免費,不需要帳號、沒有浮水印,也沒有每日次數限制。處理在你自己的裝置上完成,因此沒有需要轉嫁給你的伺服器成本。

我的 GIF 檔案會被上傳到任何地方嗎?

For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.

GIF 轉 PPM 有檔案大小限制嗎?

There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.

把 GIF 轉換為 PPM 會損失品質嗎?

No. PPM stores its data losslessly, so everything in your GIF file is preserved exactly.

可以一次把多個 GIF 檔案轉換為 PPM 嗎?

Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.

GIF 轉 PPM 能在手機、Mac 或 Chromebook 上使用嗎?

Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.

Why do some conversions take longer on first run?

The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.

I converted a file and the output is blank or unusable. What should I check?

Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
