Compress and convert

Compress video on Windows without visible quality loss

A four-gigabyte master cut down to something you can actually send, with the quality target in your hands rather than in a preset's.

You set the target

Quality is a decision about this file, not a dropdown marked "medium" that means something different for every clip.

Every delivery format

MP4, MOV, MKV and WebM, in the codecs the destination expects. One master becomes every version in a single queue.

No upload ceiling

Browser-based compressors cap the file size because they have to receive it first. This one reads the file off your disk.

Honestly: compression always throws something away

Every lossy codec discards data. The question is never whether something was lost, it is whether you can see what was lost — and on most footage there is a wide band where the file gets several times smaller and looks the same on the screens people watch it on.

That band is what a quality target is for. You choose where to sit in it, rather than accepting whatever a preset marked "medium" decided for a clip it has never seen. If a setting goes too far you will see it, so try one and look before you queue forty.

Why online compressors struggle with real footage

A web tool has to upload the whole file before it can start, and that is the slowest part by a wide margin on any domestic connection. It is also why the free ones stop at a few hundred megabytes.

Working locally removes both problems at once: nothing is transferred, and the only limit is your disk.

One app for the audio and the video

The cloud cleanup tools do audio and stop. The free video tools do video and have no AI audio at all. A single delivery usually needs both, and needing two applications to make one file is the problem this was built to end.

Questions

Before you download

Can it compress without losing any quality at all?

No tool can, and anything claiming otherwise is selling you something. Lossy compression always discards data. What you can have is loss you cannot see, which is what a quality target you control is for.

How small can a file get before it looks bad?

It depends on the footage — a talking head compresses far further than a handheld shot of moving leaves. You set the target and can try again at no cost beyond processing time.

Can it convert as well as compress?

Yes, in the same job: format and codec for the destination, and the audio cleaned in the same pass if you want it.
