MP4 to GIF Converter
Make a GIF from a short video clip without installing anything. Pick the moment, set the width and frame rate, and the browser builds the GIF right on your device. A second tab does the reverse and turns a GIF into a compact MP4. Your video is never uploaded.
Files are processed right in your browser and never uploaded to a server. Open-source libraries
TL;DR. Add an MP4, MOV or WebM file, set the start time and duration (up to 30 seconds), choose a width of 320–720 px and 10, 15 or 24 FPS, then download the GIF. The GIF → MP4 tab works the other way around.
How to convert MP4 to GIF
Add a video
Drop an MP4, MOV or WebM file onto the page. Videos up to 500 MB are accepted.
Trim the clip
Set where the GIF starts and how long it lasts. One GIF can be up to 30 seconds.
Choose size and smoothness
Pick a width of 320, 480, 640 or 720 px and a frame rate of 10, 15 or 24 FPS. Smaller and slower means a lighter file.
Download
Save the finished GIF. To go the other way, open the GIF → MP4 tab and add a GIF.
The video never leaves your device
Frames are extracted and encoded inside your browser. Nothing is sent to LiMP servers, and there is no queue, account or cloud copy of your clip.
To verify, open DevTools (F12 or Cmd+Option+I), go to the Network tab and start a conversion. No request carries your video; you will only see scripts loaded from the same site.
Why a GIF is heavier than the video
MP4 codecs store only what changes between frames, so a few seconds of video can weigh very little. GIF is a much older format: it saves each frame as a full picture limited to 256 colors. The same clip as a GIF is therefore usually several times larger.
To keep a GIF light, shorten the clip, lower the width to 480 or 320 px and use 10 or 15 FPS. Duration has the biggest effect, so trim to the essential moment. A three-second reaction loop at 480 px and 15 FPS is usually far lighter than a ten-second clip at full width.
Converting GIF back to MP4
The GIF → MP4 tab turns an animated GIF into a much smaller video file that is easier to share. It relies on the WebCodecs feature of your browser: Chrome or Edge 94+, Safari 16.4+ or Firefox 130+.
