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。
BMP
Windows BitmapWindows 的未壓縮點陣格式：每個像素都完整儲存，因此讀取簡單，但佔用的磁碟空間也非常龐大。幾乎都值得轉換成同樣無損、但小得多的 PNG。

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。

關於 BMP 轉 GIF 的常見問題
這個 BMP 轉 GIF 轉換器是免費的嗎？
是的。在這裡把 BMP 轉換為 GIF 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 BMP 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.
BMP 轉 GIF 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 BMP 轉換為 GIF 會損失品質嗎？
No. GIF stores its data losslessly, so everything in your BMP file is preserved exactly.
可以一次把多個 BMP 檔案轉換為 GIF 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.
BMP 轉 GIF 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.
