VideoUpscaler is an online AI video upscaler. Upload an MP4, MOV, MKV or WebM file up to 500 MB, pick 1080P, 2K (1440p) or 4K (2160p), and download a sharper version with the original audio kept. Every frame runs through FlashVSR, a diffusion-based video super-resolution model, so edges, text and faces are rebuilt instead of just stretched. Processing runs on cloud GPUs with nothing to install. Pricing is per second of video (1, 2 or 3 credits for 1080P, 2K or 4K), the total is shown before processing, and failed jobs are refunded automatically. Paid plans add batch upscaling of up to 10 videos. Developers can use the REST API or the remote MCP server from Claude, Cursor or VS Code. A Mac desktop app upscales locally on Apple Silicon.
