With the recent findings [0] that some of the “free file converter” websites in the wild were actually injecting malware into the results as the first stage of various attacks, I’ve wanted to stand something like this up on a server for my family. This looks like exactly what I’ve been looking for. - [0] https://www.fbi.gov/contact-us/field-offices/denver/news/fbi...

I'll hijack this to plug Stirling PDF[0], I have it running on a Raspberry Pi with docker compose and from time to time it's incredible helpfull to edit PDFs without sending them to a third party.

Maybe we could compile ffmpeg to WebAssembly and handle video conversion offline too?

That's exactly what this does: https://github.com/VERT-sh/VERT/blob/2c8cb1922cf611489022645...

    import { FFmpeg } from "@ffmpeg/ffmpeg";
`@ffmpeg/ffmpeg` is https://ffmpegwasm.netlify.app.

If you finessed that `supportedFormats` array to add video formats, this would probably just work.

Is Vert like a simplified version of https://ffmpeg-web.netlify.app/ ?

I think yes.

Nope. They process videos in a server instead.

The server is open source too: https://github.com/VERT-sh/vertd

That isn't what they stated in their website.

Is there a version of this that would support my custom presets for AVC/HEVC mp4 encoding with video filters like deinterlace/resize and similar (and/or audio filters like ebu R128)? (p.s. Also my usual input type is cinefrom/mov, which this one is not happy with for some reason)

Earlier quoted context omitted.

A relevant audience are the corporate computing inmates, who cannot install anything locally... They are happy to find utilities wrapped behind some web front.

Ahh good point. An often missed driver for the cloud-ification of everything is that it offers a way to escape corporate IT. Sending a 20mb file 2000 miles away to do something trivial to it and send it back is easier than getting permission to install an app.

It doesn't send the file though.

It's ffmpeg all the way down. I can't imagine what the internet would be if there weren't such a marvelous piece of software.

That's a whole true, creator Mr Fabrice Bellard, a 1000x developer, also create Qemu, another essential gem of software.

Why do such things need to be hosted at all? I've got a few file converter apps on my laptop. They're faster and better and you don't need to stream the data off somewhere just to process and stream back, which is silly.

Probably harder to monetize traffic and upsell subscription extras. I agree, if it's all done on the client anyway, it should just be a local app.

Wow, this is scary, I was about to ask which some of these websites are, but I found this link that lists some of them. https://www.helpnetsecurity.com/2025/03/18/fbi-free-file-con...
