Download Upsharp

Last updated: 14 November 2026

Download Upsharp (free)

The download is the full app. The free version upscales one image at a time with the Fast model at 2x, results up to 4000 pixels on the long side, with no watermark and no time limit. A licence for USD 12.99 adds 4x and 8x, the Best and Art and Anime models, folder batches and any size. One licence works on 2 of your Macs and includes a year of updates. You enter the key in the same app (Upsharp, Enter Licence Key).

A Mac App Store edition is coming. It is not released yet, and a licence from this site works only in the download from this site.

System requirements

• macOS 14 or later, Apple silicon or Intel (Apple silicon is much faster).
• Images in JPEG, PNG, HEIC, TIFF or WebP. Results up to 200 megapixels.
• No internet connection is needed to upscale. The app goes online only for your licence and for updates.

Installing

1. Open Upsharp.dmg and drag Upsharp to the Applications folder.
2. Open Upsharp from Applications and drop an image on the window.

Upsharp is signed with our Apple Developer ID and notarized by Apple, so macOS can check it. macOS may ask once whether you want to open an app downloaded from the internet. Updates come from inside the app (Upsharp, Check for Updates).
