Upsharp: AI Image Upscaler for Mac
Upsharp enlarges photos, old scans, drawings and anime art up to 8 times their size and adds believable detail instead of blur. Drop an image on the window, pick a model and a scale, press Upscale. Everything runs on your Mac.
Download Upsharp (free) · Buy a licence, USD 12.99 · Coming to the Mac App Store · macOS 14 or later
Two ways to get it:
- Download from this site, free to use. The free version upscales one image at a time with the Fast model at 2x, with results up to 4000 pixels on the long side and no watermark. A licence (USD 12.99 once, 2 Macs, a year of updates) adds 4x and 8x, the Best and Art and Anime models, folder batches and any size.
- Mac App Store: coming. The store edition will have everything unlocked. It is not released yet.
What it does
- Three models. Fast for everyday photos, Best for the most detail in photos and scans, Art and Anime for drawings and flat colour.
- 2x, 4x and 8x. 8x runs two passes and takes longer. A result can be up to 200 megapixels.
- Before and after slider to compare before you save.
- Folders and batches. Drop a folder and the results go into a folder named Upscaled inside it.
- Originals are never changed. Save as PNG, JPEG, HEIC or TIFF; EXIF, location and colour profile are kept where the format allows.
Private by design
The AI models are inside the app and run on your Mac, on the CPU and, where available, the Neural Engine. Images are never uploaded. No account, no credits, no analytics. The download goes online only to check your licence and for updates; see the privacy policy.
Questions people ask
Does Upsharp need the internet? No. The download goes online only to check your licence and to look for updates; upscaling works offline.
Can it read small text in a screenshot? No. Upsharp adds plausible detail to photos, art and old scans. It cannot recover small text that is already unreadable, so it is not a tool for screenshots.
Which Macs and macOS versions? macOS 14 or later. It runs on Apple silicon and Intel Macs; an Apple silicon Mac is much faster.
Is there a subscription? No. USD 12.99 once, for 2 of your Macs, with a year of updates. The version you have keeps working after that.
