Free AI Image Upscaler

What it does

So, I built this simple tool to offer unlimited 2x and 4x upscaling completely for free, with no signups, credit limits, or annoying paywalls, completely private. The best part? It runs entirely in your browser using your local GPU/CPU hardware (via WebGPU/WASM). Your images never leave your computer and are never uploaded to any server, making it 100% private.

Double or quadruple your photo resolution locally in your browser. Powered by WebGPU and RealESRGAN models with 100% privacy.

Instantly double or quadruple the resolution of your photos with our ultra-sharp, high-fidelity AI enhancer. Traditional online image upscalers require you to send your private photos to remote servers. This introduces privacy risks, slow upload queues, and restrictive subscription paywalls. Our AI Image Upscaler runs 100% locally inside your web browser using WebGPU and WebAssembly. By executing RealESRGAN deep learning neural networks directly on your graphics card (Nvidia, AMD, Intel, or Apple Silicon), your pictures never leave your computer or phone. Whether you are enhancing low-resolution web images, restoring vintage family photos, or sharpening digital artwork, get crystal-clear 4K…from free-ai-image-upscaler.com

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
