BMP
Windows BitmapWindows 的未压缩栅格格式：每个像素都逐一如实存储，读取简单但占用磁盘空间巨大。几乎总是值得转换为同样无损但体积小得多的 PNG。

GIF
Graphics Interchange Format每帧限制为 256 种颜色，技术上早已过时十年，却因为能自动播放动画而在各处长盛不衰。对超过几秒钟的内容来说，MP4 或 WebP 在体积只有它十分之一的情况下效果会更好。

关于 BMP 转 GIF 的常见问题
这个 BMP 转 GIF 转换器是免费的吗？
是的。在这里把 BMP 转换为 GIF 完全免费，无需账号、没有水印、也没有每日次数限制。处理在你自己的设备上完成，因此不存在需要转嫁给你的服务器成本。
我的 BMP 文件会被上传到任何地方吗？
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 转 GIF 有文件大小限制吗？
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 转换为 GIF 会损失质量吗？
No. GIF stores its data losslessly, so everything in your BMP file is preserved exactly.
可以一次把多个 BMP 文件转换为 GIF 吗？
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 转 GIF 能在手机、Mac 或 Chromebook 上使用吗？
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.
