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,…

Hey HN! I'm Mike, co-founder at Zapier and head of Zapier Labs. Today our Labs team is launching a public version of Zappy (download it here: https://zapier.com/zappy): a fast, free screen capture tool that we built for our remote team. At Zapier, we have 300+ teammates working from across the globe with no central office—we've been fully remote since day one. We've learned that increasing communication bandwidth is crucial when you're working remotely. We wanted a tool for screenshots/GIFs to supplement apps like Slack, but nothing on the market had the mix of speed and…

As I worked on my personal projects, I kept running into the same problem: There wasn’t a simple, local way to convert screen recordings into GIFs that look clean in a README.md. Recordings don’t render inline on GitHub READMEs, and I didn’t want to rely on bulky video editors or upload my files to some sketchy ad-filled site. So, I wrote a small script. I found myself using it so often that I turned it into a proper tool: minimal, local, and built for developers who care about good documentation. I’m not some elite hacker — just a dev who wanted a better way to share demos. Thought others…

Hello HN! I’m a bachelors student pursuing Artificial Intelligence, Robotics and Signal processing and during the year I had the goal to build my first AI Tool and launch it. I got inspired by how capable Whisper is, and combined the Whisper CPP Bindings along with FFMPEG.Wasm to create a tool that is capable of transcribing and captioning video files that contain one or more video tracks. Along with that, I’ve also added the support for transcribing audio files with the option to export those outputs as .SRT, .WebVTT or simply a text file. All done privately on a user’s web browser with…

Recently there were some changes to the Twitter algorithm and one of the most important ones was boosting video content even more in the feed, which got me thinking: "Why shouldn't we benefit from the algo changes and get a boost every time we are sharing some visuals?" So I spent the weekend building a tool that: - Turns your images into videos - Has 30 beautiful animated gradients that we can pick from - Is completely FREE I'd love to know your thoughts about it!

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…
