Free Topaz Video AI Alternative

Upscale video for free, right in your browser. No install, subscription, signup, watermarks or limits, and your video is never uploaded. This is a quick, free no-nonsense tool for upscaling videos with AI right in the browser. There is no software to install, and no registration or sign up required. All you need to do is input a video, and your browser will do all of the AI Upscaling and video processing. This software tool is completely free and open source. The models are trained to improve the quality of low-resolution movies, blurry social media videos, AI-generated videos, screen recordings, gaming videos and 2D and 3D animations. I built it because from previous experience as a casual user who just wants to upscale a few videos you have around, it's surprisingly frustrating. There are paid tools like Topaz Labs which are excellent but also overkill for non-professional work, or open source projects like Video2X which require a lot of setup and configuration. This tool, in contrast, is designed to be quick, fast, free, simple and easy to use. It is based on my WebSR project, which is an open-source WebSDK for applying real-time super resolution to videos on the web. The WebSR SDK allows you to apply AI Upscaling (Super resolution) models to each frame of a video directly in the browser.

Your browser does not support , a required browser feature for this tool. Try using the latest version of Chrome or Edge on a Laptop or Desktop, Or consider Fast AI Video Upscaler (server-side upscaling, works on any device)
