The fastest way to turn an MP4 into a GIF
Most online MP4-to-GIF converters work the slow way: you upload your video to their server, wait in a queue, they convert it, and you download the result. GIF Den skips all of that. Your browser already contains a hardware video decoder — the same one it uses to play YouTube — so we decode your MP4 right where it is, on your machine.
That design isn't just faster. It means your video — a screen recording with an API token visible, a clip of your kids, unreleased product footage — cannot end up on someone else's server, because it never travels. Here's how to verify that claim yourself.
Frequently asked questions
How do I convert an MP4 to GIF without uploading it?
Drop your MP4 on this page. GIF Den decodes it with your browser’s built-in hardware decoder, trims and scales it on your device, and encodes the GIF locally. No upload happens at any point — you can watch the network tab to confirm.
What MP4 codecs are supported?
H.264 (the overwhelming majority of MP4s), H.265/HEVC, and AV1 — whatever your browser can decode in hardware. Rare codecs automatically fall back to a built-in software decoder, still on your device.
How do I keep the GIF small?
Three levers: clip length (trim to the moment that matters), width (480px is the sweet spot for chat apps), and frame rate (15 fps looks smooth in most clips). You can also run the result through our GIF compressor.
Is there a watermark or signup?
No watermark, no signup, no daily limit. Free covers clips up to 30 seconds and 720px wide.
