## What is Local Video Upscaler?

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. 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.
