SubtitleGenerator
Generate, fix, translate, style and export subtitles

A free browser tool that upscales videos with AI.

AI Video Upscaler improves video clarity with a 2x AI enhancement: sharper edges, restored detail, and less noise. Drop a file into the page, compare the original and enhanced preview side by side, then download the result as MP4.
Everything runs locally in the browser, so video files stay on the device. There is no sign-up, no watermark, and no usage credits. Typical use cases include social clips, screen recordings, demos, and short videos that need a quick quality boost before sharing or editing.
Video limits are about 720p or below, under 10 minutes, and up to 300 MB on desktop (100 MB on mobile). JPG, PNG, and WebP images can also be enhanced in the same upload area. Desktop Chrome and Edge usually give the best performance.
