AI Video Upscaler is an online tool for increasing the clarity of short videos with AI. Users drop a video into the browser, review a before-and-after preview, and download an enhanced MP4. The same upload area also accepts common image formats. Work happens on the user's device rather than through a cloud upload form, and no sign-up is required. Typical uses include preparing clips for social platforms, improving screen recordings, and testing enhancement quality before further editing. Desktop Chrome and Edge generally perform best. Videos should stay within the tool's published limits on resolution, length, and file size.
