Local Video Upscaler: AI 4K HD

Make old videos sharper without uploading them. Local Video Upscaler is a private AI video enhancer for iPhone, iPad, and Mac. It upscales low-resolution videos to HD and 4K on your device, so your family videos stay with you instead of waiting in a cloud queue. Use it when you want to: - Upscale old phone videos, camcorder transfers, and low-res clips to HD or 4K - Sharpen soft footage and smooth heavy grain and compression blocks - Clean up videos that got compressed when someone sent them to you - Compare before and after on a real frame before you start - Keep the original audio, exactly as it was and in sync - Queue several videos and keep using your device while they process - Keep private videos on your own device - Work offline, including airplane mode Built for a simple workflow: 1. Choose videos from Photos or Files 2. Pick 2x or 4x, and a Natural or Clean look 3. Drag the slider to compare before and after 4. Save the upscaled copy to Photos or Files, or share it Why it is different: - On-device processing - No uploads - No account - No subscriptions - No ads - No in-app purchases - No watermark and no length limit - No tracking and no data collection Local Video Upscaler is for people who want a focused video upscaler, 4K video enhancer, and old video restore tool without sending personal videos to a server. Private by design. Your original video is never changed. Upscaling is heavy work: on a recent iPhone, a minute of 480p video takes several minutes, and Macs with Apple silicon are much faster. The app shows an estimate before you start. On iPhone and iPad, upscaling keeps going in the background and you get a notification when it's done. Output goes up to 4K, so videos that are already 4K are skipped. It sharpens soft, low-resolution footage but cannot recover heavy motion blur or out-of-focus shots. HDR videos are saved in standard dynamic range.
