How to upscale video on a Mac — free & offline
Turning a low-resolution, grainy, or old clip into clean 4K on a Mac used to mean a cloud service with per-minute fees, or a $299/year subscription. It doesn't anymore. Here's how to do it in about a minute — 100% on your Mac, no cloud, no watermark, free to try.
The short version
-
Download Crisp
Grab the free Crisp app for Mac (Apple-Silicon native, notarized by Apple) and open it. Everything runs on your Mac — nothing is uploaded.
-
Drop in your video
Drag a low-res, grainy, compressed or old video onto the window. Crisp reads the file and checks its resolution automatically. JPEG/PNG/HEIC photos work too.
-
Let Crisp choose — or pick a preset
AUTO picks the right model and scale for you. Prefer control? Choose Enhance, Low-light, or Anime, and set the scale to 2×, 3× or 4× (up to 4K). Turn on Smooth motion to interpolate to a higher frame rate.
-
Export
Crisp upscales, denoises and sharpens the clip on-device and saves a clean new file beside your original — no watermark, no subscription, no waiting on an upload.
Tip: just describe what you want
Crisp has a plain-English box — type “upscale to 4K and clean up the low-light noise” or “make this vertical for TikTok” and it builds the plan for you. No wall of sliders to learn.
It's more than an upscaler
The same app handles the rest of the job most people need after upscaling — all offline, on your Mac:
| Lane | What it does |
|---|---|
| Enhance | AI upscale + denoise + restore + low-light cleanup, up to 4K |
| Montage | Auto-cut a highlight reel, a tightened condense, or a music montage |
| Reframe | Fit a clip to 9:16, 1:1, 4:5 or 16:9 with a blurred fill (Reels/TikTok) |
| Speed | Slow-mo or fast-forward with pitch-corrected audio |
| Color | One-tap looks — cinematic, warm, cool, vibrant, moody, B&W |
What kind of Mac do I need?
Any Apple-Silicon Mac (M1 or newer) runs the fast tier at interactive speed — 1080p to 4K in the time it takes to grab a coffee. The optional generative Max quality lane, for badly damaged footage, is happiest with 32 GB+ of memory and is the slow, best-quality, overnight option.
Why on-device beats a cloud upscaler
- Private. Your footage never leaves your Mac — nothing to upload, nothing stored on someone else's server.
- Free of per-render fees. Cloud upscalers charge by the minute; Crisp is a one-time purchase with a free tier.
- Works offline. On a plane, on set, or with no connection — it just runs.
- No watermark. Every export is clean.
