About

The "Video to GIF Converter" is a free tool that converts MP4, WebM, and other video files to GIF animations entirely in your browser.

It uses ffmpeg.wasm — a WebAssembly port of FFmpeg — running directly in the browser. No video data is ever sent to any server. You can safely convert private or confidential videos.

Features include intuitive timeline trimming, output size control (original/480px/320px), FPS selection (10/15/24), and high-quality GIF quantization using FFmpeg's palettegen/paletteuse filters, delivering superior color fidelity compared to typical online GIF converters.

How to Use

STEP 1

Upload a Video

Drag and drop or click to select your MP4, WebM, MOV, or AVI file. On first use, ffmpeg.wasm (~25MB) will be downloaded and cached.

STEP 2

Set Range & Options

Drag the timeline handles to set start and end points. Adjust output size, FPS, quality, and loop settings to suit your needs.

STEP 3

Download Your GIF

Click "Convert to GIF" and wait for processing. Preview the result and download your GIF with one click.

Glossary

GIF (Graphics Interchange Format): An image format developed in 1987. Supports up to 256 colors, animation, and is universally supported. Widely used for sharing short animations on social media and messaging apps.
ffmpeg.wasm: A WebAssembly port of the open-source FFmpeg multimedia toolkit. Enables video trimming, format conversion, and GIF export entirely in the browser without a server.
palettegen / paletteuse: FFmpeg's GIF optimization filters. palettegen analyzes the video to generate the optimal 256-color palette, which paletteuse applies to each frame — minimizing quality loss from GIF's color limitation.
FPS (Frames Per Second): The number of frames displayed per second. Higher FPS means smoother animation but larger file size. 10–15fps is the typical sweet spot for GIFs.
SharedArrayBuffer: A JavaScript API that allows multiple Web Workers to share memory. Required for high-performance ffmpeg.wasm operation. Needs Cross-Origin-Opener-Policy (COOP) and Cross-Origin-Embedder-Policy (COEP) HTTP headers.

faq,

FAQ

Q.Is my video uploaded to a server?: No. ffmpeg.wasm (WebAssembly version of FFmpeg) runs entirely inside your browser, so no video data is sent over the network. Only the ffmpeg.wasm core files are downloaded from a CDN on first use.
Q.How good is the GIF quality?: High-quality GIF quantization is performed using FFmpeg's palettegen/paletteuse filters. Color accuracy is better than typical online tools, and dithering is optimized as well.
Q.Why is loading slow the first time?: On first use, the ffmpeg.wasm core files (~25MB) are downloaded from a CDN. After that, they are cached by the browser, so subsequent uses are near-instant.
Q.The GIF file size is too large.: Setting the output size to 320px and FPS to 10 can reduce the file size significantly. Keeping the clip to 15 seconds or less is also recommended. File size varies with video content (motion, number of colors).
Q.Conversion is taking a long time.: The WebAssembly version of FFmpeg is slower than native. Depending on the length, resolution, and quality settings, it can take tens of seconds. Setting quality to "Balanced" and size to "320px" can speed things up.
