How to verify a file checksum
- Choose the downloaded file with the file picker.
- Compare the SHA-256 (or MD5) value with the checksum published by the software vendor.
- If they match exactly, the file is complete and has not been tampered with.
Frequently asked questions
Is my data uploaded anywhere?
No. This tool runs entirely in your browser. Your data never leaves your device, and nothing is stored on our servers.
Is MD5 secure?
No — MD5 and SHA-1 are broken for security purposes. They are still fine for detecting accidental corruption. Use SHA-256 or better for anything security-related.
Can I hash large files?
Yes. Files are read locally; very large files (several GB) depend on your device’s memory.
