Verifying downloads
Check a file hash before you trust a downloaded release asset, export, or backup file.
File Hash Checker
File Hash Checker helps you calculate file digests in the browser so you can verify file integrity, compare downloads, and confirm whether two files match. It is useful for release assets, backups, and transfer checks.
Tool interface
What this tool does
File Hash Checker helps you calculate SHA-256, SHA-1, and MD5 file hashes in the browser for integrity checks, file comparisons, and download verification.
Related next steps include SHA256 Hash Generator, MD5 Hash Generator, and the Free browser-based developer tools page if you want to keep working on the same task from a different angle.
When to use it
Use it when you need to verify file integrity, compare downloads, or confirm whether two files match. It is especially useful for release assets, backups, exported reports, and transferred files.
If you need to compare the result against a known digest or another hash workflow, continue with SHA256 Hash Generator. For broader developer checks, the Free browser-based developer tools page is a useful next stop.
How to use it
Upload a local file, calculate its digests, and compare the output with the hash you expected to see.
- Choose the local file you want to inspect.
- Run the hash check and review the SHA-256 and SHA-1 results shown in the output.
- Compare those values with your expected hash before you trust the file for release, backup, or transfer work.
Example
This example shows the kind of input and output the tool is designed to handle in a typical browser workflow.
Example input
Upload a local fileExample output
SHA-256: ...
SHA-1: ...
MD5: ...Common use cases
Comparing file integrity
Use it when you need to confirm whether two copies of a file still match after transfer or storage.
Recording browser-side digests
A local hash output is useful for QA notes, release checklists, and basic integrity comparisons.
Pairing with other hash workflows
If you need a related digest workflow next, continue with SHA256 Hash Generator.
FAQ
What does File Hash Checker do?
File Hash Checker helps you calculate SHA-256, SHA-1, and MD5 file hashes in the browser for integrity checks, file comparisons, and download verification.
When should I use File Hash Checker?
Use it when you need to verify file integrity, compare downloads, or confirm whether two files match. It is especially useful for release assets, backups, exported reports, and transferred files.
How is File Hash Checker different from SHA256 Hash Generator?
File Hash Checker focuses on this exact task. Use SHA256 Hash Generator when you need to create SHA-256 hashes in the browser for checksums, integrity comparisons, and security-focused workflow support instead.
Does File Hash Checker run in the browser?
Yes. This tool runs in the browser so you can work with the input on the page without sending it through a custom backend on this site.
What should I use after File Hash Checker?
A good next step is SHA256 Hash Generator or the Free browser-based developer tools page.
