Is it safe to download DLL files?
No. And the part that gets less attention: in most cases it does not work either, so you take the risk and still do not fix the problem.
Why it does not work
A runtime DLL is one piece of a package. Dropping vcruntime140.dll next to a program leaves out the other libraries it expects, the registry entries that record the runtime as installed, and the side-by-side assembly manifests Windows uses to resolve versions. The error often just moves to the next missing file.
For system files the mismatch is worse. Components like kernel32.dll and ntdll.dll are tied to your exact Windows build. A copy from a different build is not a repair, it is a different program, and the usual result is a machine that stops booting.
And when the file belongs to a game, the version has to match that build. Copying UnityPlayer.dll from another game fails for the same reason a car key does not open a different car.
Why it is risky
A DLL is executable code, and its whole purpose is to be loaded into other programs. A modified one runs with whatever permissions the program that loads it has. There is no way to tell a good copy from a tampered one by looking, which is exactly why distributing individual system libraries has been a malware channel for more than two decades.
The one thing that would settle it, a hash published by the publisher, is the thing these downloads never come with. That is the whole reason this site exists: every package we point at is listed with the SHA-256 the publisher declared, so you can check it before you run it.
Is dll-files.com safe?
It is the site most people mean when they ask this, and the honest answer is that it is the wrong question. We have no evidence that it distributes anything malicious and we are not suggesting it does. The problem is that the approach does not work regardless of who is offering the file.
- Nobody can verify it for you. The one thing that would settle whether a DLL is genuine is the hash the original publisher declared. A third party re-hosting the file cannot produce that, so you are trusting the intermediary rather than checking the file.
- The version still has to match. These files belong to a package. Even a perfectly clean copy of the wrong build leaves you with a program that loads it and then fails somewhere less obvious than before.
- The name attracts imitators. Search results and ads for these terms are full of lookalike domains, and telling them apart from the address bar is not realistic. That risk exists whatever the original site does.
Install the runtime that owns the file instead. It is free, it comes from the publisher, it registers the file properly, and we list it below with the URL and SHA-256 so you can check what you downloaded before running it.
Asking about a site that hosts whole programs rather than loose libraries? That is a different question with a different answer: are software download sites safe.
Where these files actually come from
Each of these resolves to a package we index, with the publisher's own URL and a verifiable hash.

See every file we have mapped, including the ones where the answer is repairing Windows rather than installing anything.
If you already downloaded one
- 01Delete it, and do not run whatever installer came with it.
- 02Run a full scan with Windows Security or your antivirus of choice.
- 03If you copied it into System32 or SysWOW64, run sfc /scannow to restore the original from Microsoft's catalogue.
- 04Then fix the actual problem: install the runtime package the file belongs to.
