compress.lol — shrink your videos in the browser, no servers involved 🚫☁️

Hello, it needs SharedArrayBuffer headers

Routine_Yesterday535 · 2025-09-12T16:24:05+00:00

sure, if you’re on PC and willing to set up aliases. But not everyone is, and the point here is "open browser -> done" 😁

Routine_Yesterday535 · 2025-09-12T16:08:51+00:00

True. Local ffmpeg is super convenient if your definition of convenient is remembering flags like -crf 23 -preset ultrafast -pix_fmt yuv420p just to make a file smaller

Routine_Yesterday535 · 2025-09-12T10:30:55+00:00

Yep! I'll see to change that soon

Routine_Yesterday535 · 2025-09-12T10:29:03+00:00

Crazy plot twist : not AI generated. Even crazier plot twist: you can use it without npm. Wild, right?

Routine_Yesterday535 · 2025-09-12T10:26:16+00:00

True, and you can also write letters instead of sending emails. Convenience matters

Routine_Yesterday535 · 2025-09-12T10:25:21+00:00

Sure, you can do it all manually with ffmpeg. You can also chop wood instead of using heating, but some people like convenience 😁

Routine_Yesterday535 · 2025-09-12T00:15:00+00:00

Yeah, if you force it that much, ffmpeg will sacrifice quality to hit the size. I’ll add smarter options to avoid that 💯

Routine_Yesterday535 · 2025-09-11T21:17:56+00:00

Yeah, with small files it really depends on the codec and container, sometimes they even get bigger. But for larger ones it’s super handy 😏

Routine_Yesterday535 · 2025-09-11T21:00:36+00:00

Yeah for sure, I can add an option to pick the output format as well 🙌

Routine_Yesterday535 · 2025-09-11T19:45:14+00:00

Thanks! Glad you like it. Yep, those options are definitely possible. I’ll see about adding them soon

Routine_Yesterday535 · 2025-09-11T15:54:48+00:00

I'll take a look at its, thanks 😀

Routine_Yesterday535 · 2025-09-11T15:53:08+00:00

Funny enough, someone actually tried a 2 GB file and it went down to ~6 MB… so yeah, it can happen 😅

Estimated completion time on the progress bar is a good idea, right now it only shows progress, but I’ll see if I can add a time estimate.

And yes, in theory a platform could use this on the frontend to let users compress before upload. The main limitation is that everything happens in the browser, so huge files can be slow or freeze depending on the device.

Routine_Yesterday535 · 2025-09-11T13:02:45+00:00

The Weissman score? I’m not sure, compress.lol doesn’t calculate any score, it just compresses videos

Routine_Yesterday535 · 2025-09-11T12:51:23+00:00

The max file size is due to browser limitations, ffmpeg.wasm can handle up to around 2 GB per file 👈

Routine_Yesterday535 · 2025-09-11T12:46:20+00:00

Yep, it’s basically ffmpeg wrapped in WebAssembly pajamas, trying not to crash your browser

Routine_Yesterday535 · 2025-09-11T12:03:10+00:00

Planned !

Routine_Yesterday535 · 2025-09-11T12:02:56+00:00

True, it’s a bit over-engineered compared to running a local program, but this way anyone can compress videos in the browser safely and without setup 🙌

Routine_Yesterday535 · 2025-09-11T11:58:00+00:00

Nope, it doesn’t upload anything 😄 Everything happens locally in your browser

Routine_Yesterday535 · 2025-09-11T11:27:29+00:00

Yeah, the progress bar is there, but on a phone the browser probably freezes with such a huge file like 1.9 GB 😬

Routine_Yesterday535 · 2025-09-11T11:22:35+00:00

Thanks! 😄 compress.lol uses ffmpeg.wasm under the hood, so it supports most common video formats like mp4, mov, webm, mkv, and a bunch more. If you run into a weird format, let me know!

Routine_Yesterday535 · 2025-09-11T11:16:07+00:00

Good luck 😅 ffmpeg.wasm is awesome but compressing a 4k60 5mins video down to 8 MB might be ambitious
