MP4, WebM or GIF — choosing the right export

Three formats cover meme video, and they are not interchangeable. The short version: MP4 for anywhere you post a video, WebM when file size matters and the destination supports it, and GIF only when the platform genuinely refuses to accept video.

MP4 is the default and should stay that way

MP4 with H.264 video is the most compatible video format in existence: every phone, browser, platform and messaging app plays it. It compresses efficiently, supports audio, and is what every social platform expects to receive. Unless you have a specific reason to pick something else, export MP4. The newer H.265 codec compresses better but has patchier support, which is exactly the wrong trade for something you want to spread.

WebM for the web, when you control the destination

WebM with VP9 or AV1 gives noticeably smaller files at the same quality, which matters when you are embedding video on your own site and paying for the bandwidth. Browser support is good and improving. What it does not have is universal support in native apps and messaging: send a WebM to someone's phone and it may simply not open. Use it on the web, not as your share-everywhere file.

GIF looks bad because it is thirty-five years old

GIF is limited to 256 colours per frame, has no audio, and compresses so poorly that a three-second clip can outweigh a minute of MP4. The banding and dithering you see in meme GIFs is the format failing to represent video, not a stylistic choice. Most platforms that appear to host GIFs quietly convert them to MP4 on upload for exactly this reason. Export GIF only where nothing else is accepted — some forums, some email clients, some older chat systems.

Practical export settings

For MP4: H.264, AAC audio, the platform's native resolution, and a bitrate high enough that you cannot see blocking in motion — 8–12 Mbps is generous for 1080p and costs nothing. For WebM: VP9 at a similar quality target. For GIF: reduce the frame rate to 10–15fps, crop tightly, and keep it under a few seconds, because those are the only levers that make the file size survivable.

Editing happens entirely in your browser — nothing is uploaded. This guide is general information, not legal advice; if you are publishing commercially or using someone else's footage, check the rules that apply where you are.

Frequently asked questions

Why is my GIF bigger than the video it came from?

Because GIF stores each frame with weak compression and no motion prediction, while video codecs store only what changes between frames. A moving background is nearly free in MP4 and enormously expensive in GIF.

Which format keeps audio?

MP4 and WebM. GIF has no audio at all — if a clip depends on sound, exporting it as a GIF removes the joke.

Is a transparent video possible?

Yes, in WebM with VP9 alpha and in a few other formats, but support is inconsistent and most social platforms flatten it against black. For anything you post publicly, composite the background yourself and export a normal opaque video.

Make it in the browser. Cut, caption, overlay, remove the background, add music and export MP4, WebM or GIF. Free, and your video never leaves your device.
