NextGenUp is a free tool for enlarging images and video, available for macOS, Windows 10/11, and Linux, with a self-hosted web app option. Image modes include Quick, Quality, Enhance, and Ultra, with image upscaling up to 8K. Video upscaling reaches 4K and has basic and professional AI modes. Enhance mode reduces noise and blur without changing the original resolution, while GFPGAN v1.4 detects faces and restores detail that general upscaling may miss. Models, FFmpeg, and the server run on the user's hardware, so files do not leave the computer. Processing uses the CPU by default and automatically uses GPU acceleration when available. In supported browsers, the web app can use WebGPU on Chrome or Edge 113 and later. The MIT-licensed project requires no subscription, watermark, or account. Web files are limited to 2 GB, and older processed files are cleaned up after 24 hours. The listed output format is PNG.
Who it is for
NextGenUp suits people who want local image or video upscaling on desktop or through a self-hosted web app. It may also fit users looking for face restoration or noise and blur reduction without enlarging an image.
