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。

转换前值得了解

GIF is lossless and WebM is lossy. This direction discards some information in the encode step. In practice, many files look identical at default settings, but this is a one-way loss. Keep the GIF source if you might need a perfect copy later.
GIF 是唯一能承载动态画面的图像格式，因此这会生成一段真正的视频，采用源文件原本的帧时序，而不是由静态图片拼成的幻灯片。

FAQ

关于 GIF 转 WebM 的常见问题

这个 GIF 转 WebM 转换器是免费的吗？

是的。在这里把 GIF 转换为 WebM 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 GIF 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.

GIF 转 WebM 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 GIF 转换为 WebM 会损失质量吗？

WebM is a lossy format, so some detail is discarded when it is encoded. At the default quality setting the change is often not visually obvious; keep your original GIF file if you might need it again.

可以一次把多个 GIF 文件转换为 WebM 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.

GIF 转 WebM 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.
