# File Checksum Verifier & Multi-Hasher

Drop any file to instantly compute SHA-256, SHA-1, SHA-512, and MD5 hashes with automatic expected checksum matching.

## What is File Checksum Verifier & Multi-Hasher?

The File Checksum Verifier checks that a downloaded file is intact and has not been tampered with. Choose the file, and the tool computes its SHA-256, SHA-1, SHA-512 and MD5 checksums; paste the checksum published by the software vendor into the verification box to get an instant match or mismatch. Hashing happens entirely in your browser, so large ISO images and installers are never uploaded.

## How to use File Checksum Verifier & Multi-Hasher

1. **Select the file** — Switch to File Input and choose the downloaded file (or type text).
2. **Paste the expected checksum** — Copy the SHA-256, SHA-1, SHA-512 or MD5 value from the download page.
3. **Check the result** — The tool shows whether the computed hash matches.

## Frequently asked questions

### Which checksum should I compare?

Use whichever the publisher lists — SHA-256 is the most common today. The tool calculates all supported algorithms so you can match any of them.

### What does a mismatch mean?

The file differs from the original: the download may be incomplete or corrupted, or it is not the file the publisher released. Download it again from the official source.

### Is uppercase vs lowercase important?

No. Hex checksums are compared case-insensitively.
