Toolbox: Run FFmpeg, Imagemagick, 7Zip and Friends in the Browser

I got sick of sketchy online converter sites that phone home and may keep your files and walking non-technical friends through brew/apt/choco installs every time they need ffmpeg or imagemagick and telling them what command to run. So I built Toolbox, a 100% open source site that compiles my most-used command-line tools to WebAssembly and runs them fully client-side: - FFmpeg (video + audio) - ExifTool (metadata) - 7-Zip (archive/zip/rar/7z) - ImageMagick - Pandoc Roadmap: - Batch mode - Shareable presets. Complex commands can be saved as URLs so you can send a…

Toolbox: Run FFmpeg, Imagemagick, 7Zip and Friends in the Browser launched on July 10, 2025 with 5 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

What it does

Avoid sketchy websites when trying to manipulate files by using a client side browser tool to do the work. Powered by tools like ImageMagick, FFmpeg, 7Zip compiled to wasm.

  • CompressX, my FFmpeg wrapper for macOS2024 · compressx.app · ▲170

    Hey HN, just wanted to share my success story with CompressX, my FFmpeg wrapper for macOS. For those who may not be familiar, FFmpeg is a powerful tool for converting, streaming, and recording audio and video content. I started CompressX as a weekend project to serve my 9-5 jobs, primarily to compress demo videos for uploading to GitLab and sharing with my colleagues. It took me 2 weeks to make the first working version. I shared the demo on Twitter and the reaction was extraordinary. People loved it, they said that I was bringing the Pied Piper to life. Four months later, I hit the $9,000…

  • Video CommanderApr 2026 · video-commander.com · ▲87

    I've been building open-source tools in the video/multimedia space for 10+ years. Finally shipped the commercial product I always wanted to exist — Video Commander, a desktop app that consolidates FFmpeg, ffprobe, MediaInfo, VMAF and more into a single workspace where you can inspect, encode and analyze video. Built with Tauri + Rust backend, React frontend. FFmpeg and VMAF. Not a cool AI/LLM project, just a tool I've been heads-down building over the last six months. Happy to answer any questions!

    FFmpeg Pages – because I was tired of fighting FFmpeg2025 · ffmpegs.pages.dev · ▲62

    You ever just want to shrink a video… and suddenly you’re buried in flags, half-broken StackOverflow answers, and 10 tabs open just to figure out one command? That’s been me. Every. Single. Time. So I built FFmpeg Pages — a dead-simple collection of the commands I kept searching for. No fluff, no digging, just the stuff that actually works.

  • Ez FFmpeg – Video editing in plain EnglishDec 2025 · npmjs.com · ▲420

    I built a CLI tool that lets you do common video/audio operations without remembering ffmpeg syntax. Instead of: ffmpeg -i video.mp4 -vf "fps=15,scale=480:-1:flags=lanczos" -loop 0 output.gif You write: ff convert video.mp4 to gif More examples: ff compress video.mp4 to 10mb ff trim video.mp4 from 0:30 to 1:00 ff extract audio from video.mp4 ff resize video.mp4 to 720p ff speed up video.mp4 by 2x ff reverse video.mp4 There are similar tools that use LLMs (wtffmpeg, llmpeg, ai-ffmpeg-cli), but they require API keys, cost money, and have latency. Ez FFmpeg is different: - No AI – just…

    FFmpeg in plain English – LLM-assisted FFmpeg in the browser2025 · vidmix.app · ▲179

    I found that I am using ChatGPT more and more to get the FFmpeg command I need, but the process can be a bit tedious: copy-pasting commands, dealing with input file names and locations, making sure the prompt contains enough info about the input files. This site attempts to solve that. You just describe what you want to do, pick the input files and an LLM (currently DeepSeek) generates the FFmpeg command. You can then run it directly in your browser or use the command elsewhere.

  • FFmpeg-over-IP – Connect to remote FFmpeg servers2024 · github.com · ▲147

    Dear HN, I’m excited to show case a personal project. It has helped me quite a bit with my home lab, I hope it can help you with yours too! ffmpeg-over-ip has two components, a server and a client. You can run the server in an environment with access to a GPU and a locally installed version of ffmpeg, the client only needs network access to the server and no GPU or ffmpeg locally. Both and client and the server need a shared filesystem for this to work (so the server can write output to it, and client can read from it). In my usecase, smb works well if your (GPU) server is a windows machine,…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  • Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  • Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  • Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
