Compute SHA-1/256/384/512 of any file and verify integrity — 100% browser-based.
Drop a file or click to browse
Any file type · Any size · Never uploaded to server
Hashes computed in-browser via Web Crypto API. Files are never uploaded. Works offline.
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.
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.
Choose your desired hash algorithm
Select from SHA-1, SHA-256, SHA-384, or SHA-512 depending on your specific security or verification needs.
Wait for the hash computation
The tool uses the Web Crypto API to process your file locally without uploading any data to a server.
Paste an expected hash to verify
Optional: Paste a known checksum into the verification field to instantly check if the file matches the original.
Copy the generated file hash
Review the computed hash results and copy the string to your clipboard for your records or further use.
