Offline Video Upscaler
Upscale video & photos to 4K, locally on your Mac
OFF turns 480p–1080p video and photos into crisp 4K using on-device AI, right on your Mac. Your audio is kept, your files never leave your machine, and there's no subscription. Free for the first 100,000 users.
Hey Product Hunt 👋
I kept hitting the same wall with video upscalers: upload your footage to the cloud, wait, and pay credits per clip. Modern Macs are plenty fast for this, so I built OFF — 4K Upscaler to do it all locally.
What it does:
• Upscales 480p/720p/1080p video to 1080p or 4K with on-device Real-ESRGAN
• Keeps the original audio, exports clean MP4 (H.264/H.265)
• Photo upscaling too (2×/3×/4×) with a before/after slider
• Batch + a live queue with progress and ETA
• 100% offline and private — nothing is uploaded
It runs comfortably on an 8GB M2 Air thanks to a segmented pipeline and RAM-aware tiling.
To say thanks to early users, the first 100,000 get it lifetime free — no subscription, no per-video credits.
I'd love your feedback, especially on quality and speed with your own clips. Happy to answer anything!
