VideoUpscaler – 视频画质增强到 4K

把任意视频发送到 VideoUpscaler，用 AI 把视频画质增强到清晰的 1080P、2K 或 4K。云端处理，无需安装软件。

VideoUpscaler is an AI video upscaler that turns blurry, low-resolution clips into sharp 1080p, 2K or 4K video. This extension is the shortest path from any video you find in Chrome to the upscaler. What it does • One-click start: open the popup and click "Upscale a video" to jump to videoupscaler.co, where you upload a clip, choose 1080p, 2K or 4K and download the result. • Right-click any video: on a <video> player or an .mp4 / .mov / .webm link, choose "Upscale this video with VideoUpscaler". The extension copies the video link, shows a short note, and opens VideoUpscaler so you can save the file and drop it into the uploader. • Clear next steps: if a player only streams the video (no file link), the extension tells you to save the original file first instead of failing silently. Why VideoUpscaler • AI video enhancer, not a resize: every frame is run through an AI video model that rebuilds edges, texture and faces, so a 480p or 720p clip comes out as real 1080p→4K detail instead of a stretched blur. • 1080p, 2K and 4K output: pick the exact resolution you need. Old phone footage, screen recordings, anime, archive film and vlogs all work. • Nothing to install: processing runs in the cloud. Any modern browser is enough, and new accounts get 10 free credits to try it. • Keeps your audio: the original soundtrack is copied into the upscaled file. • Pay per second: the price is shown before processing. You only pay for the seconds you upscale. Privacy The extension itself collects no data. It has no host permissions, no content scripts, no analytics and no remote code. It only uses the context menu and the clipboard (to copy the video link you right-clicked), and it opens videoupscaler.co in a new tab.
