The trade-off everyone made

Most enhancers want your photos. Tanngo wants nothing.

The cloud way

  • Photos uploaded to a server you don't own
  • Account required · email · maybe credit card
  • Subscription that quietly renews forever
  • Originals indexed, retained, sometimes trained on

The tanngo way

  • Model and photos stay on your machine
  • No account · no email · no signup form
  • One download, one license, no recurring charge
  • Local, inspectable, and free during beta

What you get

Heavy lifting, light footprint.

Runs 100% offline

Once installed, tanngo never touches the internet. Your photos stay where they are.

AI upscaling + denoising

Built on modern diffusion models, optimized for desktop GPUs and Apple Silicon. Output quality on par with cloud tools, without the upload.

Batch processing

Drop a folder. Whether it's 50 photos or 5,000, tanngo works through them in the background.

Transparent about what it does locally

Every step is local and inspectable. No hidden cloud pipeline, no telemetry.

Looks like this

One command. Local from start to finish.

Things people ask

Common questions

Does tanngo upload my photos?

No. Tanngo runs entirely on your device. After installation, it doesn't need internet access at all.

Do I need an account?

No. There's no signup, no login, no email required. Download, install, run.

What hardware do I need?

Apple Silicon Macs (M1 or later), Windows or Linux machines with an NVIDIA GPU (8 GB+ VRAM recommended), or a CPU fallback for smaller jobs.

How does it compare to cloud photo enhancers?

Output quality is in the same class as modern cloud tools. The difference is that nothing leaves your machine — no upload latency, no privacy trade-off.

Is tanngo free?

Free during beta. The plan after launch is a one-time license fee — no subscription.

Is tanngo open source?

Not at this time. The underlying model weights are licensed and can't be redistributed.

A note from the maker

Why tanngo exists

I got tired of cloud apps demanding photo uploads for what should be a local job. So I built the thing I wanted. It restored my grandmother's scanned wedding photos on a quiet Sunday, and then friends kept asking how they could get it. That's where tanngo started.
