PDF.to reads each frame of your WebP and re-encodes the sequence as a MP4 video with a real video codec. Animated WebP files become smooth MP4 clips; a single still WebP becomes a short fixed-length MP4.
The MP4 contains the same frames once through. Looping is a player setting rather than part of the video, so add a loop attribute when you embed the MP4 if you want the endless-loop behavior a WebP has by default.
与 WebP 相比 MP4 有多大?
+
Typically a fraction of the size. Video codecs compress motion between frames far better than a WebP can, so a multi-megabyte WebP routinely converts to a MP4 a tenth of the size with no visible loss.
Does the MP4 have sound?
+
No. A WebP has no audio track, so the resulting MP4 is silent. You can add a soundtrack afterward with our video tools if you need one.
Standard MP4 video does not support an alpha channel, so transparent areas of the WebP are flattened onto a solid background. Pick the background color in the options panel before converting.
我可以把很多 WebP 文件转换到 MP4 吗?
+
Yes. Upload several WebP files at once and each is converted to its own MP4; the results are zipped for one download.
Is the WebP to MP4 conversion free?
+
是的, 在自由大小限制之内。 PRO 提高限制,允许更高的输出分辨率,并平行运行转换。
Will the MP4 play on social media and messaging apps?
