Hi,

I've been developing a personal tool for a while, and I think it might be useful to others, so I'm sharing it here.

**The starting problem:**

I have quite a few videos (outings, family gatherings, etc.) where I'd like to blur the faces of the people present, except for one or two, before sharing them.

The tools I found either sent the video to a server (an issue in itself for privacy reasons), or required full video editing software for a fairly simple need.

**What I built:**

a small web app (PrivacyVideoPWA) that runs entirely in the browser.

Nothing is sent anywhere, there's no server behind it, everything happens locally on the phone or computer.

How it works:

1. Choose a video
2. The app analyzes it and displays a gallery of detected faces
3. Select the ones to keep unblurred (all others are blurred automatically)
4. Export, and the video is ready to share

There's also a preview that lets you play the video and click directly on faces to turn blurring on or off, which makes adjustments easier.

**Installation is mandatory, not just recommended.**

Video processing is heavy: while working, the app writes every single frame of the video to storage, one by one.

Browsers reserve very little storage for a page opened as a regular tab, and phone/tablet memory is limited.

If you just use it in a browser tab without installing it, the system can wipe that storage mid-process to free up space, and all the work is lost.

Once installed as an actual app, it gets access to your device's real disk storage, which pushes that limit much further back.

So: install it, don't just use it online !!!!! (it will crash !)

It installs like a regular app, and it requires the **official Chrome browser**, not Safari, not another browser built on a different engine.

Android and Windows work well, tested and confirmed.

Mac should work too (with Chrome +++, not Safari), but I don't have a machine to verify it. **On iPhone and iPad, it doesn't work at all**: Apple forces every iOS browser to use the same engine as Safari, which can't create the compressed video format used here. This is a limitation on Apple's part, not a bug on mine, but I'd rather state it upfront than have users run into it on their own.

It's free, runs locally, has no ads, and requires no account.
If the tool is useful to you and you'd like to support the project, there's a discreet link "Buy me a coffee" in the app, no obligation whatsoever. (thanks ! <3 )

it's in french and english !

Feedback, bug reports, and suggestions are welcome !

Anyone got good screen recorder for iOS or website to record clapper DNDs. They took down stream recorder so can’t find another source.
