Upscal vs Waifu2x-Extension-GUI

Upscal uses built-in AI models to enhance low-resolution photos and videos on a device. Its image tools target blurry, compressed and old photos, aiming to improve edge sharpness, texture and detail. Video enhancement works frame by frame, and built-in super-resolution models can enlarge images and videos up to 8×. Batch processing is supported, with output formats including JPG, PNG, WebP, MP4, MOV and M4V. Upscal is available on iOS, macOS and Windows. Once the app and required resources are installed, normal image and video enhancement can run offline. The privacy policy says processed media is handled locally rather than sent to an external processing server, though anonymous technical diagnostics may be transmitted, including app and operating-system versions, device category, crash traces and error logs. The free plan costs nothing, has no subscription and includes core image and video enhancement with offline processing; no account is required. The maker permits commercial use when users follow applicable laws and have the necessary rights to the input content. Results vary with source quality and device capability, and enhancement cannot perfectly recover detail that was never captured.

Waifu2x-Extension-GUI is a portable Windows desktop application for enlarging images, animated media, and videos with AI super-resolution. It processes images, animated GIF, APNG, WebP, and video, supports batch jobs, and can enlarge up to 4x. Video frame interpolation is included for creating additional frames. Built-in super-resolution engines include Waifu2x, SRMD, RealSR, Real-ESRGAN, Real-CUGAN, Anime4K, ACNet, and RTX Super Resolution; interpolation options include RIFE, CAIN, DAIN, and IFRNet. The application supports AMD, Nvidia, and Intel GPUs, including multi-GPU processing for its built-in engines. Its portable workflow is to unzip the Windows x64 package and start it, with presets for one-click setting changes. Multithread controls and customizable settings support workflow automation. The project lists English, Simplified Chinese, Traditional Chinese, Japanese, and Spanish. It says no data is uploaded or collected and no server is used, though internet access checks updates and refreshes the donation QR code. Personal use is free; commercial use requires Patreon Premium from $4.99 a month.
