Why use LightBox
The modern replacement for GIF
Animated WebP looks sharper and weighs far less than a GIF, so your loops load fast and stay crisp. Drop in a video and get a web-ready animation back in seconds.
Free, no signup, no watermark
Convert common video and image formats free, without an account or watermark. Pro adds specialist formats and tools for bigger or repeated jobs.
Real control over the output
Tune quality, fps, trim, crop, resize, loop count and audio, or use the frame-picker to grab a single still. Get exactly the file you need, not a one-size-fits-all export.
Your files stay private
Free conversions are processed on our server and auto-deleted after about an hour. Downloads stay on your device. Choose lifetime Pro for a permanent hosted library.
Free forever. Pro when you need more.
Convert common formats free. Lifetime Pro adds more capacity and permanent hosting, with no subscription.
