About 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.

How to Use File Hash Checker

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

   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
