by Moritz Bunkus · GPL-2.0
MKVToolNix is a set of tools to create, alter and inspect Matroska files under Linux, other Unices and Windows.
These URLs are the ones Moritz Bunkus declares in its own manifest. We do not proxy or shorten them, and we do not host a copy.
More than one architecture below. Check which one your Windows is if you are not sure.
Run this against the file on disk. If the output does not match the hash below, the file is not what Moritz Bunkus published. Delete it.

Got a different hash, or one you cannot place? Paste it into the hash checker and it will tell you which program and version it belongs to, past releases included.
The macOS build as Homebrew declares it, with the same treatment as the Windows side: the publisher's own URL and a hash to check it against.
| Signal | Finding | Points |
|---|---|---|
| SHA-256 hash published | 4 of 4 installers ship a SHA-256 hashWithout a published hash there is no way to prove the file you downloaded is the file the publisher built. | 30 / 30 |
| Binary provenance | 4 on a domain owned by the publisherThe strongest signal against a repackaged installer: the file should come from the publisher, not from a mirror nobody vouches for. | 35 / 35 |
| Served over HTTPS | 4 of 4 over HTTPSAn installer fetched over plain HTTP can be modified in transit. | 15 / 15 |
| Release recency | last release about 1 months agoSoftware that has not shipped in years accumulates unpatched vulnerabilities. | 15 / 15 |
| Licence declared | GPL-2.0A declared licence tells you what you are actually allowed to do with the software. | 5 / 5 |
Extensions MKVToolNix registers itself to handle.
Yes, in the sense we can actually verify: the installer downloads from mkvtoolnix.download, which is a domain we have tied to Moritz Bunkus.
Every one of the 4 installers on this page comes with the SHA-256 Moritz Bunkus declared, so you do not have to take our word for it: hash the file you downloaded and compare.
What this does not tell you is whether the software itself is any good, or whether you want what it does once installed. A publisher can ship something you would rather not run and the download is still authentic. We answer the question we can measure and leave the other one to you.
If Windows says “Windows protected your PC” when you run it, that is SmartScreen reporting reputation, not a malware verdict — it shows up on perfectly legitimate software from small publishers and on releases that are simply new. The reverse matters more: no warning does not mean the file was checked.
How the 100/100 score is calculated · why the source matters more than the reputation
Windows ships with a package manager, and this program is in it. The identifier below is the one Microsoft's repository uses, which is also where the download URL and hash on this page come from.
Install
winget install --id MoritzBunkus.MKVToolNix --exactUpgrade later
winget upgrade --id MoritzBunkus.MKVToolNixWhy --exact: without it winget matches on name as well as identifier, and a search that returns more than one package makes it stop and ask rather than install. Pinning the identifier is what makes the command safe to put in a script.
Not installing anything, or getting an error back? The commands that actually come up covers upgrading everything at once, what --include-unknown is for, and why winget can be missing from a machine that should have it.
The version history of MKVToolNix, each release with the download URL the publisher declared at the time and the SHA-256 to check it against. Useful when an update breaks something and you need to downgrade to a build that worked.
We do not host any of these files and never re-upload them, which is the difference between this and an old-version download site.

The file names, so you can tell what you have. Their hashes are in the hash checker and in the downloadable archive.
Publishers take old builds offline without warning, so a link here can stop working even though the hash stays correct forever. If you already have the file, the hash is what matters: it tells you whether what you have is what they published.
Every MKVToolNix version with a published manifest, newest first. The most recent ones are listed above with their file names and hashes.
Not related to MKVToolNix — just other entries, each with its own official URL and published hash.
