File Checksum & Hash Calculator

Calculate MD5, SHA1, SHA256, and SHA512 hashes for any file. Verify file integrity without uploading.

Load File

Select the local file you want to generate a hash for.

Select Hash

Choose MD5, SHA-1, or SHA-256 as the verification method.

Verify the integrity of your files by calculating their checksums. Drag and drop any file to instantly generate its hash using MD5, SHA-1, SHA-256, or SHA-512 algorithms. This is crucial for verifying that downloaded files have not been corrupted or tampered with. Our tool reads the file locally using the FileReader API. Even for large files, the data acts locally and is never uploaded to a server, saving bandwidth and ensuring privacy.

Frequently Asked Questions

No. The file is read locally by your browser to calculate the hash.

Yes, but very large files (GBs) might take longer to process depending on your CPU speed.

It ensures the file you have is exactly the same, byte-for-byte, as the source, protecting against corruption or tampering.
