A hash is a kind of digital "fingerprint" of a file or piece of text — if the content changes even slightly, the resulting hash changes completely. That's why hashes are commonly used to verify that a file you downloaded is truly identical to the original, with no part corrupted or altered along the way.
File Hash Checker — MEA Tools
Compute MD5, SHA-1, up to SHA-512 hashes of a file or text, and compare them automatically, right in your browser.
Open File Hash Checker →Steps to check a hash
- Open tools.meaecosystem.com/file-hash-checker.
- Choose "File" mode to check a file, or "Text" to compute a hash from text you type directly.
- Upload a file from your device, or type/paste the text.
- Check the algorithm(s) you need — SHA-256 is usually enough for most verification needs, but you can also compute several at once.
- If you already have a reference hash (from an official download page, for instance), paste it into the comparison field — the tool will automatically tell you if it matches or not.
Why does the hash need to match exactly?
A fundamental property of hash functions is that any change to a file — even a single bit — produces a hash that's completely different, not just "slightly" different. So if the computed hash matches exactly with the one provided by the official source, it means your file is identical, byte for byte, to the original.
MD5, SHA-1, or SHA-256 — which should you use?
For simply checking whether a file was corrupted during download, all of these algorithms work equally well. But if the goal is more about security (making sure a file wasn't deliberately tampered with by someone else), SHA-256 or higher is recommended, since MD5 and SHA-1 are known to have weaknesses that can be exploited in certain scenarios.
Frequently asked questions
Is my file uploaded to a server when its hash is computed?
No. The hash computation runs directly on your device. The file is never sent anywhere.
Why is my hash different even though the file is the same?
First check whether you're using the same algorithm as the reference source — the MD5 and SHA-256 hashes of the same file will naturally differ since they're different algorithms. If the algorithm matches but the hash still differs, the files likely aren't actually identical.
Is there a file size limit?
There's no limit from the service side, since everything is processed on your own device. For very large files, processing time depends on your device's specs.
