Will the video look as good as the original GIF?

Yes — video codecs like H.264 and VP9 are far more efficient than GIF's 256-color palette, so at the same visual quality the video file is usually dramatically smaller. Higher quality settings preserve more detail at the cost of a larger file.

What's the difference between MP4 and WebM?

MP4 (H.264) has the widest compatibility across devices, apps, and social platforms. WebM (VP9) often compresses slightly better and is well supported in modern browsers, but has patchier support in some older apps.

Is there a file size limit for the GIF I upload?

Yes, GIFs up to 50MB are supported. Larger or longer GIFs take more time to convert since everything runs in your browser.

Why is the MP4 so much smaller than the GIF?

GIF stores every frame as a full image from a limited 256-color palette with no motion compression, which is very inefficient. Video codecs like H.264 only encode the differences between frames and use far more sophisticated compression, so the same animation typically shrinks by 70-95% when converted to video.

Why were my GIF's dimensions changed slightly?

H.264 requires even width and height values, and many GIFs are exported with odd dimensions. The tool automatically rounds down to the nearest even number so the video encodes correctly — this trims at most one pixel from the width and height.

Will the video loop like the GIF did?

Not automatically — an MP4 or WebM file doesn't carry a "loop forever" flag the way a GIF does. Looping is handled by whatever plays the video: most web embeds, social platforms, and video players offer their own loop toggle. If you need the file itself to repeat without relying on the player, use the Repeat option before converting.
