TapirUpscale

FreeAI Video Upscaler sharpens blurry, low-resolution clips and upscales them to HD or 4K as clean MP4 files, right in your browser. Key features: • 2x and 4x upscaling to 1080p or 4K • Preview one frame before and after upscaling • Supports MP4, MOV, WebM and MKV files • Free mode runs locally with no upload and no sign-up • Optional cloud GPU processing with the Pro plan • Audio copied into the output MP4 when the format allows A standard player only stretches each frame when you go full screen, which makes footage look soft. This upscaler estimates the detail that the extra pixels should contain, so a 720p clip can become 1440p and a 1080p clip can become 4K. You choose the scale, the model and the detail level, then render a preview to compare results before you process the full video. The free version works entirely on your own device. Decoding, upscaling and encoding happen locally, so private footage is never uploaded to a server. There is no watermark and no queue. Speed depends on your GPU, so older laptops and long videos take more time, and your computer may run hot during processing. This tool suits content creators restoring old family videos, filmmakers and editors improving low-resolution source clips, and anyone who needs a sharper MP4 for YouTube, social media or a presentation without installing desktop software.
