A JavPlayer alternative that works in the browser
JavPlayer is a Windows video player that reduces mosaic in real time while you watch. PureFrame takes a different approach: you upload the video, AI reconstructs the mosaic areas on cloud GPUs, and you download a new MP4 that plays on any device. Every video gets a free preview first.

What is JavPlayer?
JavPlayer is a desktop player for Windows. It analyzes the video, estimates the size of the mosaic and applies filters and super-resolution to reduce it during playback, and it can record the processed video. Its documentation states that it cannot restore the pre-mosaic image and that low-quality videos or unusual mosaics may not be detected. The trial version limits recordings to 640 pixels wide and one minute.
