Video Upscaler — Offline Video Enhancement

Enhance local videos with GPU processing. Preview, compare and export without uploading.

Upscale local videos and compare the results without uploading your files. Video Upscaler uses your device’s GPU and a built-in AI model to enhance video frames at up to 2× resolution, directly in Chrome’s side panel. PREVIEW BEFORE YOU PROCESS Choose a local video, select the whole video or a time range, and generate a preview of up to 3 seconds. Pick Fast, Balanced or Detailed quality to suit your device and footage. SEE THE DIFFERENCE Open video comparison in a separate tab. Drag a divider across the image, view both videos side by side, or switch between before and after. Synchronized playback helps you compare the same moment; audio plays only from the enhanced video. SAVE YOUR RESULT Download the enhanced video as MP4 or WebM, depending on browser codec support. Compatible audio is preserved; trimmed clips and previews may re-encode it. LOCAL AND OFFLINE Videos and processing stay on your device. The model is bundled with the extension, so enhancement works offline after installation. No account, cloud upload or subscription is needed. Comparison copies are stored locally. HOW TO START 1. Click the extension icon to open the side panel. 2. Choose or drag in a video and try a short preview. 3. Enhance, compare and download your result. Chrome 140 or later and a supported GPU are required. Keep the side panel open while processing or saving. Output size and speed depend on your device; hardware limits can reduce enlargement below 2×. Results depend on the original footage. This extension processes local files, not webpage videos, live streams or DRM-protected media. It does not promise 4K restoration or real-time processing.
