What does a match mean?

It means your file is identical to the one the checksum was made from. It does not prove that the checksum itself came from a trusted source, so get it from the official site.

Which checksum should I use?

SHA-256 or SHA-512 when the page offers them. MD5 and SHA-1 are older and can be forged, so treat a match as weaker proof.

No. The checksum is calculated on your device in your browser, and the file never leaves it.

File Checksum Checker

Check that a downloaded file is genuine: paste the published checksum and compare it with your file.

Your files never leave your device

Choose the file, then paste the checksum from the download page. The algorithm is detected from its length.

About this tool

File Checksum Checker compares your file with the checksum published by its author, to confirm the download was not damaged or tampered with. Paste the checksum and the tool detects whether it is MD5, SHA-1, SHA-256, SHA-384 or SHA-512. The file is checked in your browser and never uploaded.

Good to know: Files up to 500 MB. A match proves the file equals the original, but not that the checksum came from a trusted place.

Your files are processed entirely in your browser — nothing is ever uploaded to any server. Verify it yourself

Hash Generator

Create MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text or a file, and compare them with a hash you have.

Link Checker

Break a link into its parts and see warning signs for phishing, such as look-alike characters and shorteners.

Base64 Encode & Decode

Convert text or a file to Base64, or decode Base64 back to text, with an optional URL-safe format.
