v1.0.0

NextGenUp 1.0.0 is the first public release — a free, open-source AI image and video upscaler that runs entirely on your machine. Upscale photos to 8K and videos to 4K with Real-ESRGAN, restore faces with GFPGAN, and never upload a file to anyone's server.

Downloads

Platform File
macOS Apple Silicon (M1–M4) NextGenUp_1.0.0_aarch64.dmg
macOS Intel NextGenUp_1.0.0_x64.dmg
Windows 10/11 x64 NextGenUp_1.0.0_x64-setup.exe (or .msi)
Linux x64 NextGenUp_1.0.0_amd64.AppImage, .deb, or .rpm

Everything is bundled — the AI models, FFmpeg, and the processing engine. No Python, no dependencies, no setup.

macOS note: builds are not notarized with Apple. On first launch, right-click the app and choose Open.

Highlights

  • Image upscaling in four modes: Quick (browser AI), Quality (FFmpeg Lanczos + CAS), Enhance (same resolution, AI cleanup), and Ultra (server AI — full quality from any device)
  • Video upscaling to 4K: Basic (FFmpeg) and Pro (Real-ESRGAN frame by frame), audio preserved, portrait and landscape handled automatically
  • Enhance mode — keep the original resolution but remove blur, noise, and JPEG artifacts
  • Face restoration (GFPGAN v1.4) — every detected face aligned, restored, and blended back seamlessly
  • Batch processing with per-image progress and zip export
  • Before/after comparison slider on every image result
  • Cancellable jobs — stop any run mid-flight and start another mode instantly
  • Auto-updates — the app checks GitHub releases on launch; updates are cryptographically signed
  • Private by design — 100% local processing, no cloud, no telemetry, no account, no watermark

Notes

  • Face restoration requires the GFPGAN model (~340 MB), which is not bundled to keep installers small: drop GFPGANv1.4.onnx into the app-data models/ folder (see the README), or answer yes in setup.sh when running from source.
  • The bundled FFmpeg builds are GPL; FFmpeg retains its own license. NextGenUp itself is MIT.
