CodecCrunch

A No Thrills ProRAW to HEIF converter

What it does

CodecCrunch is a result of an app, I made for myself first. What makes the App interesting is that it converts ProRAW to HEIF but keeps the HDR Tone Mapping intact. In contrast to other converters that remove the HDR completely. The App also removes the artificial sharpening and clarity as well Metadata. And converts also ProRES to HEVC or Rec. 709. Again keeping the tone mapping where its wanted.

    I built heicconvert.it — a fast, private, and completely browser-based HEIC/HEIF image converter that supports output conversion to JPEG, PNG, WebP, or even AVIF. Why I made it: - Photos from iPhones often come in HEIC format, which isn’t broadly supported everywhere. - Existing tools tend to require uploads, compromise privacy, or feel clunky. - I wanted a zero-friction, client-side tool where conversion happens instantly, in your browser, without ever touching a server. Try it - https://www.heicconvert.it - No signup, no tracking, and no data is sent to anyone. What’s…

    TL;DR: private, in-browser converter that turns pretty much any image file format into standard JPEGs. Everything runs locally. No uploads. This started as a five-minute job and forty hours later... I wanted to convert a HEIC without uploading it anywhere, so I wrestled Emscripten/WebAssembly to run Google's Jpegli inside a Web Worker. Now there's a small UI and it handles a bunch of formats. Just about the only thing it can't decode is JXL - but there's still some JPEG XL magic in there: XYB perceptual color quantization is enabled by default via Jpegli. The upside of all this…

    A fast, privacy-first image converter that runs in browserOct 2025 · imageconverter.dev · ▲48

    Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions. So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy. What it does Convert images between JPG, PNG, WebP Works offline once loaded (PWA support) How it works It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices. Why I built it I wanted an instant, no-ads,…

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
