MP4 to GIF Converter — Free, Online, No Upload

Video is great, but it's also heavy and requires a player. GIF is everywhere — it plays automatically in Slack, embeds in emails, loops in documentation, and requires zero interaction from the viewer.

If you've got a funny clip, a quick screen recording, a product feature demo, or a short reaction video, a GIF is often the right format for sharing it. It auto-plays, it loops, and it works everywhere without a "press play" button.

Making a GIF that isn't enormous comes down to three levers: length, dimensions, and frame rate. This converter handles two of them for you: every GIF is 480 pixels wide at 15 frames per second, which looks fine for Slack reactions, README demos and screen recordings. The lever left to you is length — keep the clip under about five seconds. A full-resolution, 30 fps, ten-second GIF can balloon past 50 MB; the same clip trimmed and resized often lands under 5 MB.

It's also worth knowing that several places people think of as "GIF platforms" — X/Twitter, Slack, Discord — quietly re-encode your GIF to silent MP4 behind the scenes because it's far lighter. If your destination accepts a silent MP4, that's usually the better choice. Convert to a true .gif when the target genuinely needs the format: an email signature, a GitHub README, an older forum, or a docs page that embeds .gif directly.

The trade-off: GIF doesn't support audio, and its 256-colour palette means it works best for short clips with limited colour variety. For longer videos or footage with lots of colour gradation, keep the MP4.

When to convert MP4 to GIF: - Sharing a clip to Slack, Teams, or Discord (GIFs play inline, videos need clicking) - Embedding a demo in a README, docs page, or presentation - Creating a looping reaction or meme from a short clip - Social media posts where auto-play GIFs get more engagement than linked videos

Typical file sizes: A 5-second MP4 clip (1080p) is roughly 5–20 MB. The same clip as a GIF is typically 10–80 MB — GIF is far less efficient than modern video codecs. GIF works best for very short clips (under 5 seconds) at reduced resolution.

GIF uses a 256-colour palette, which means converting from full-colour MP4 video involves colour quantisation — a lossy step. The LZW pixel data is then stored losslessly, but the palette reduction discards colour detail. Expect banding or dithering artefacts on clips with smooth gradients or complex colour.

Transparency: MP4 does not support transparency. GIF supports 1-bit transparency (a single colour can be designated as transparent).
