Image Enhancer

Upscale low-res images 4x right in your browser

What it does

Image Enhancer takes small, low-resolution images and enlarges them up to 4x without the usual mush. Thumbnails, product shots that are too small for a marketplace listing, avatars, images saved from chats or the web, over-compressed screenshots. The AI model runs entirely inside your browser, so nothing is uploaded anywhere. Free, no account, no watermark.

Enlarge small, pixelated or over-compressed images up to 4x without the mush. A free AI image enhancer for thumbnails, product photos and screenshots that runs in your browser, so your images never leave your device. No sign-up, no watermark.

Thumbnails, product shots, avatars, images saved from chats, screenshots that got compressed into mush. A free AI enhancer that makes them bigger and sharper right in your browser, so they never leave your device. No sign-up, no watermark. A product photo that fails the marketplace size requirement. A thumbnail that turns to blocks the moment you enlarge it. A picture saved from a chat that arrived squeezed to a fraction of its size. Most fixes mean uploading to a website that watermarks the result or locks it behind a sign-up. This one rebuilds the detail in your browser and hands the image straight back. Three steps, a few seconds. Nothing to upload, no account to make. Open the extension…from devexthub.com

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
