Frequently Asked Questions (FAQ)

What is a checksum?

A checksum is a unique string of characters derived from a file’s contents using a hash function. It's used to verify file integrity and detect accidental or malicious changes.

Why should I use this calculator?

Using a checksum calculator helps ensure that files haven’t been tampered with or corrupted during transmission. It’s commonly used for verifying software downloads and sensitive data transfers.

Which hash algorithms does this tool support?

Our tool supports popular checksum algorithms such as MD5, SHA-1, SHA-256, SHA-384, and SHA-512.

Is this checksum calculator secure?

Yes, this tool operates entirely in your browser. No files are uploaded to any server, ensuring complete privacy and security.

Can I check the checksum of any file?

Yes, you can generate checksums for most file types including documents, images, videos, and software binaries.

How do I verify a checksum?

Simply upload your file, choose a hash type, and compare the output with the original checksum provided by the source. If they match, the file is intact.

What’s the difference between MD5 and SHA?

MD5 is faster but less secure, and is now mostly used for basic file verification. SHA (especially SHA-256) offers stronger cryptographic security and is widely recommended for critical applications.

Is this checksum calculator free to use?

Yes, our checksum calculator is 100% free to use, with no registration or installation required.
