VidStudio, a privacy-focused, browser-based video editor.
Technical Positioning
A frictionless, privacy-centric browser-based video editor that processes files locally (no uploads, no accounts), offering multi-track editing, MP4 export, and mobile compatibility, leveraging WebCodecs, FFmpeg WebAssembly, and WebGL.
SaaS Insight & Market Implications
VidStudio addresses a significant pain point for businesses handling sensitive media: the privacy and security risks associated with uploading video files to cloud-based editors. Its 'no uploads, no accounts' and local processing model (WebCodecs, FFmpeg WebAssembly) offers a compelling value proposition for industries with strict data governance requirements, such as legal, healthcare, or internal corporate communications. For B2B SaaS, this highlights a market for privacy-by-design media tools that prioritize client-side processing. The technical sophistication (WebGL, Web Workers) ensures a performant user experience, demonstrating that advanced functionality can be delivered without compromising data sovereignty, a key concern for enterprise adoption.

Show HN: VidStudio, a browser based video editor that doesn't upload your files
Hi HN,
I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your
machine.Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile.Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it.
FFmpeg compiled to WebAssembly handles final encode, format conversion, and anything WebCodecs does not cover. Rendering goes through Pixi.js on a WebGL canvas, with a software fallback when WebGL is
not available. Projects live in IndexedDB and the heavy work runs in Web Workers so the UI stays responsive during exports.Happy to answer technical questions about the tradeoffs involved in keeping the whole pipeline client-side. Any feedback welcome.Link: vidstudio.app/video-editor
Developer Debate & Comments
I've seen dozens of these posted to HN. Surprisingly, there is a lack of browser based video editors for media libraries, which means I have to load the video over the network using WebDAV or Samba, edit it locally, and then upload it back. It's a niche use case, but the people who manage their own photos and video storage are generally tech savvy, so it's surprising that no such tools exist.
Wild that privacy became a feature and not the default. Building in this space too and the no uploads needed angle is surprisingly hard to communicate to users who've been trained to expect everything to live in the cloud.
Sorry for the significantly unrelated comment:Does anyone know if there is any limitation to create a "https-local://" or something like that, which guarantee that things are only downloaded, and never uploaded?
Curious how you're handling the MP4 export entirely client-side — are you using FFmpeg compiled to WebAssembly, or something custom built around the WebCodecs API?
Wild that apps used to be completely local, no accounts, no uploads, and we're back to that as a value prop.
Let me just say the performance is absolutely incredible, and the persistence is so transparent. I actually was given access to an in-browser video editor that chokes pretty quickly so I'm impressed. The tracks didn't seem to work well for me. I'm on Firefox on Windows and couldn't drag and drop tracks to change the order, there doesn't seem to be any layer transformation tools (position, rotation, scale) that I could find to counteract it not handling footage of different aspect ratios (I.E. portrait and landscape).
Interesting approach—privacy-friendly editing without uploads is compelling. Curious how you handle performance and large files purely in-browser, and what trade-offs there are vs server-based editors.
I've built a similar video editor and have been considering pure client side implementation vs transcoding into a known format beforehand, went with transcoding for wider format support and easier video playback implementation.I'm interested in how you handle demuxing different container formats any which ones are supported?I get "Audio decode failed: your browser cannot decode the audio in "41b1aee9-ac65-43f6-b020-e8fed77c3c72_webm.bin". Try re-encoding the file with AAC audio." for a WEBM with no audio.h264/aac MP4 works, is that demuxed with mp4box.js? I noticed seeking (clicking or scrubbing on timeline) initializes a new VideoDecoder and destroys the previous one for every new frame, leading to abysmal performance as you lose decoder state and a lot of decoding work has to be repeated. Plus the decoder reinitialization time. Is that because the demuxing logic doesn't give precise access to encoded frames? iirc mp4box.js didn't support that last time I checked.
How does it compare to https://omniclip.app/, https://tooscut.app, or https://clipjs.mohy.dev/ ?
> FFmpeg compiled to WebAssembly handles final encodeFFmpeg's license is the LGPL 2.1. VidStudio looks like closed source software, I couldn't see any indication that it's free software. You're distributing this software to run in the client's browser. I'm not a lawyer but I think you're in breach of the terms of the LGPL.https://www.ffmpeg.org/legal.html
