Checksum Verifier
Generate text and file hashes, then compare with expected values for integrity checks.
All hashing is processed locally in your browser. Files are not uploaded to any server.

- Select a hash algorithm (such as SHA-256 or MD5).
- Text hash: Enter or paste text and see the hash instantly.
- File hash: Drag and drop or upload a file to calculate its hash automatically.
- To verify, paste an expected hash into the compare field for automatic matching.
Tip:All hashing runs locally in your browser. Files are never uploaded.
When would you use this?
- When you download an installer, archive, or document and want to confirm the file is complete and unchanged.
- When you need to compare your own calculated hash with an official SHA-256, MD5, or similar value.
- When you want to check whether two texts or two files are actually identical in content.
How should I choose between SHA-256, SHA-1, and MD5?
For new integrity-check workflows, SHA-256 is the safer default. SHA-1 and MD5 are usually kept for compatibility with older systems or published legacy values.
If the hash matches, does that guarantee the file is safe?
Not completely. A matching hash usually means your file content matches the source-provided file, but that only helps if the source itself is trustworthy. Integrity and safety are not the same thing.
Why does my expected hash show as invalid format?
The usual reasons are extra spaces, line breaks, non-hex characters, or a length that does not match the selected algorithm. Check both the character set and expected length.
Does this tool upload my file to a server?
No. Text and file hashes are calculated locally in your browser so you can verify integrity without uploading the content.
If two files have different names but the same hash, what does that mean?
It usually means the file contents are identical and only the filenames differ. Hash comparison checks bytes, not filenames.
