Accuracy, safety and device considerations
Web Crypto needs enough memory to digest each selected file and a secure origin. A matching checksum confirms bytes match the reference, not that the file is free from malware.
Heavy file operations may require additional processing memory or a browser-compatible library. We show an error instead of labeling an incomplete export as successful. Verify important results before professional use.
Frequently asked questions
Does checking SHA-256 change my file?
No, it reads the content to calculate a digest without modifying the source.
Can I verify an official download?
Yes, paste the trusted publisher's expected digest and compare results.
Can a checksum prove a file is safe?
No. It only checks integrity against a reference hash.
