File Hash Checker

Compute cryptographic hashes of any file — SHA-1, SHA-256, SHA-384, and SHA-512 — directly in your browser using the Web Crypto API. Drag and drop a file, or click to pick one. Paste an expected hash to instantly verify file integrity. No file is ever uploaded to any server. Works with files of any size and type.

Why choose File Hash Checker?

File Hash Checker computes cryptographic hashes like SHA-256 and SHA-512 directly within the browser using the Web Crypto API. Because processing happens entirely client-side, files are never uploaded to any server, ensuring complete privacy. It also provides instant verification by allowing users to paste an expected hash.

Good to know: Very large files processed entirely in browser memory may be limited by local device performance and browser constraints.

How to Use File Hash Checker

Verify file integrity and compute cryptographic hashes like SHA-256 directly in your browser.

1. 1

   Select or drag your file

   Click the upload area to pick a file from your device or simply drag and drop it into the browser.

2. 2

   Choose your desired hash algorithm

   Select from SHA-1, SHA-256, SHA-384, or SHA-512 depending on your specific security or verification needs.

3. 3

   Wait for the hash computation

   The tool uses the Web Crypto API to process your file locally without uploading any data to a server.

4. 4

   Paste an expected hash to verify

   Optional: Paste a known checksum into the verification field to instantly check if the file matches the original.

5. 5

   Copy the generated file hash

   Review the computed hash results and copy the string to your clipboard for your records or further use.
