Short answer
Download Upscayl 2.15.0 from the official GitHub release, upscayl.org, winget, Homebrew or Flathub; all five deliver the project's own files. On Windows the file is upscayl-2.15.0-win.exe, 249 MB. Before running it, compare its SHA-256 with the value in the table below. The app is free, so any paid "Upscayl" download is not the real one.
How do I download Upscayl safely?
- Pick one official channel. Use GitHub releases, upscayl.org, winget, Homebrew or Flathub. Skip download portals and bundles.
- Download the file for your system. Choose the installer or package for your operating system from the table below; ignore blockmap, latest.yml and Source code files.
- Check the SHA-256. Run Get-FileHash in PowerShell (or shasum -a 256 on macOS and Linux) and compare the result with the table.
- Install and upscale one test image. Run the installer, open Upscayl and upscale one small image to confirm your GPU works.
Or install it with winget: press Win+R, paste and press Enter.

Each release has one installer or package per system plus update files you should ignore. The table lists the files for version 2.15.0 with their exact size. A SHA-256 is shown where one is published or was checked: GitHub records no digest for these files, so the Windows installer hash comes from the winget manifest (we hashed the GitHub file and it matches), the macOS disk image hash from the Homebrew cask, and the portable ZIP hash was computed by Pixel Bench from the GitHub file.

How do I check the Upscayl download is genuine?
A matching SHA-256 proves your file is byte for byte the one the project published. Open PowerShell in your Downloads folder, run the command below and compare every character with the table. On macOS or Linux, run shasum -a 256 followed by the file name. If the value differs, delete the file and download it again from GitHub. Microsoft documents the command on its Get-FileHash page.
Get-FileHash .\upscayl-2.15.0-win.exe -Algorithm SHA256You can skip this check with winget: the winget manifest points at the same GitHub URL, records the same hash and refuses a file that does not match. Upscayl's build configuration names the publisher Upscayl Team, and the README warns that SmartScreen or an unverified-publisher dialog may appear.
Which Upscayl download channels are official?
Five channels deliver the project's own builds, and the README links each of them. Anything else, including download portals and "pro" or paid versions, is not from the Upscayl team.
| Channel | What it gives you | Link |
|---|---|---|
| GitHub releases | Every file, every platform, release notes | github.com/upscayl/upscayl/releases |
| upscayl.org | The project's download page, linking the same files | upscayl.org/download |
| winget (Windows) | Upscayl.Upscayl; checks the installer hash | winget manifest |
| Homebrew (macOS) | brew install --cask upscayl | Homebrew cask |
| Flathub (Linux) | org.upscayl.Upscayl | Flathub listing |
Frequently asked questions
Is Upscayl safe to download?
Yes, from the official channels. Upscayl is open source under AGPL-3.0, its code and releases are on GitHub, and the winget and Homebrew manifests record the same file hashes as the release. Windows may still show SmartScreen or an unverified-publisher dialog; the README says to click More info and Run anyway.
What is the latest version of Upscayl?
Version 2.15.0, published on GitHub on December 25, 2024. The version, file names and sizes on this page come from GitHub's release data, which the site refreshes every day.
Is there an Upscayl Microsoft Store or App Store version?
The README links a Mac App Store listing for macOS. For Windows it links only the GitHub release and upscayl.org, and winget installs the GitHub file. Other Windows store listings are not linked by the project.
