Preview and download the animated GIF created in your browser.
Upload a video, choose a short range, and convert it to preview the GIF here.

The video stays on your device. FFmpeg runs inside the browser only after you start conversion.

Quick answer

A video to GIF converter turns a selected video range into an animated image.

This browser-side version is best for short clips with modest width and FPS.

Best inputs

Short clips

GIF files grow quickly, so a 1-5 second range is usually easier to share.

Clear loop moment

Pick a range with simple motion and avoid long transitions or camera shake.

GIF conversion method
The tool uses ffmpeg.wasm to sample frames, build a palette, and export an animated GIF.
FPS controls animation smoothness and file size.
Width controls pixel count and output weight.
Color count affects visual richness and compression.
Example, Assumption, and Limitation
Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Example

Upload a short MP4, choose 2.0 to 4.5 seconds, set width to 480px and 10 FPS, then download a looping GIF.

Assumption

The source file is under 200MB and the chosen range is short enough for browser memory.

Limitation

GIF output does not contain audio and can be much larger than video for long or high-resolution clips.

Common use cases
These pages are built for lightweight browser-side work, examples, and planning.

Docs snippets

Turn a short product interaction into a README or help article GIF.

Social previews

Create a lightweight animated teaser from a video moment.

Bug reports

Share a tiny visual loop without uploading a full video.

Landing pages

Create small motion previews when video embedding is overkill.

Frequently asked questions

Does this video to GIF converter upload my file?

No. The selected video is processed in your browser with ffmpeg.wasm and is not sent to a backend.

Why should GIF clips be short?

GIF files can become very large quickly. Short ranges, lower width, lower FPS, and fewer colors keep output more practical.

Which video formats work best?

MP4 and WebM are the safest first inputs. Other containers depend on browser and FFmpeg support.

Can the GIF include audio?

No. GIF is an image animation format and does not contain audio.
