Convert videos to animated GIFs right in your browser.

(MP4 or WebM, under 50MB recommended)
Converting screen captures, product walkthroughs, and video clips into shareable animated GIFs usually requires uploading heavy video files to remote cloud servers. ImageUp runs the complete FFmpeg encoding engine directly inside your web browser via WebAssembly, generating smooth, high-color looping GIFs with two-pass palette optimization and zero video uploads.
Select an MP4, WebM, or MOV video clip from your computer or phone.
Choose your target width (480px recommended), frame rate (10–15 FPS), and quality compression tier.
Watch real-time frame encoding progress in the browser and download your looping GIF.
Leverages WebAssembly multi-threading to execute native FFmpeg encoding filters entirely inside your local browser tab.
Generates a custom 256-color palette for each scene to eliminate color banding, pixel noise, and washed-out tones.
Confidential product demos, internal bug captures, and personal video recordings remain strictly on your local device.
GIF is an older format (from 1987) that stores full uncompressed bitmap frames without modern temporal video compression. To keep GIF sizes small, reduce the width to 480px and cap the frame rate to 10 or 15 FPS.
GIFs work best for short 2 to 10 second loops. Longer clips can produce huge file sizes and take longer to encode in the browser.
No. The entire FFmpeg binary is loaded automatically into your web browser as a WebAssembly module with no installation required.
No. Video decoding, frame extraction, palette computation, and GIF rendering occur 100% locally on your machine.
GIFs carry reactions, software demos, and social posts. This converter turns MP4 or WebM clips into looping animations in the browser, no video editing software required, whether it's a gaming moment or a help-center tutorial.
Frame rate, output width, and quality are all under your control, which is how you keep a GIF fast-loading on mobile and under platform limits. The encoder optimizes the color palette so animations stay vibrant instead of washed out.
A local encoding engine means personal recordings and internal screen captures never upload. Rendering uses your computer's own processing power, with no subscriptions or bandwidth caps.
