How to Convert a Video to GIF
A GIF is the one animation format that plays absolutely everywhere without a player, without autoplay restrictions and without anyone tapping a button. That is why they are still the default for a bug report, a quick demo, a reaction or a step-by-step in documentation. The catch is that GIF is an ancient format with no real compression, so a careless conversion produces a twenty megabyte file for three seconds of video. This tool gives you the three controls that actually matter — length, size and frame rate — and shows the result before you download.
Upload your video
MP4, WebM or MOV. The file is read locally in your browser and never uploaded anywhere.
Trim and set the size
Drag the start and end sliders to pick your clip, then choose a width and frame rate.
Convert and download
The GIF appears with its real file size, so you can adjust and try again before saving.
Keeping the File Size Under Control
GIF stores every frame as a near-complete image with a palette of just 256 colours. There is no motion compression the way there is in video, so the file size is roughly length × frame rate × area. Double any one of those and the file roughly doubles. That is the entire mental model you need.
In practice, length is the biggest lever, and also the one people ignore. A five second clip is a quarter the size of a twenty second one. Be ruthless with the trim sliders — almost every GIF that gets shared is better for being shorter anyway.
After that, frame rate. Ten frames per second reads as perfectly smooth for screen recordings and most motion; twenty-five is broadcast-smooth and more than doubles the size for a difference most people will not notice. Only push it higher for fast, detailed motion. Width is the third lever, and 480 pixels is plenty for anything that will be viewed inline in a chat, an issue tracker or a document.
Common Situations This Tool Solves
Showing a bug in an issue tracker
A GIF plays inline in GitHub, Jira and Linear with no click required, which makes it far more likely someone actually watches your reproduction steps.
A quick product demo in documentation
Ten seconds of GIF at the top of a help article explains an interaction better than three paragraphs describing it.
Reaction clips and memes
A short reaction from a video is the native currency of group chats, and GIF is the only format that autoplays everywhere without a tap.
Email and Slack where video does not embed
Most email clients will not play video, and many chat tools only preview certain formats. A GIF just works.
Frequently Asked Questions
How do I convert a video to GIF for free?
Upload your video, trim it with the start and end sliders, choose a width and frame rate, and click Convert. Free, no signup and no watermark.
Why is my GIF so large?
GIF has no motion compression - every frame is stored almost in full. File size scales with length, frame rate and dimensions, so trimming the clip shorter is by far the most effective fix.
What frame rate should I use?
Ten frames per second looks smooth for screen recordings and most motion while keeping the file small. Go higher only for fast, detailed movement.
Is there a length limit?
Clips are capped at thirty seconds, because beyond that GIFs become impractically large and browsers start struggling to encode them.
Is my video uploaded to a server?
No. Frames are captured and encoded entirely inside your browser - your video is never uploaded, stored or seen by anyone.
Which video formats work?
Anything your browser can play, which in practice means MP4, WebM and usually MOV. If a file will not load, converting it to MP4 first will fix it.
Does the GIF have sound?
No. The GIF format has no audio support at all - it is images only. If you need sound, keep it as a video.
Why do the colours look slightly off?
GIF supports only 256 colours per frame, so gradients and photographic content get approximated. This is a limitation of the format, not the conversion.
Can I make a GIF from a screen recording?
Yes, and it is one of the best uses - screen recordings have flat colours and limited motion, which is exactly what GIF compresses well.
Why is conversion slow on long clips?
Each frame has to be captured by seeking the video and then quantised to a 256-colour palette. That work scales with the number of frames, so shorter clips at lower frame rates convert much faster.
Does it work on my phone?
Yes, though encoding is slower on phone hardware and long clips may run out of memory. Keep mobile conversions short.
Is this video to GIF converter really free?
Completely free, with no limits, no watermark, no signup and no premium wall. Everything runs in your browser, so there are no server costs to pass on.
