Frequently Asked Questions (FAQ)
Q. Is my file uploaded to a server?
A. Absolutely not. This site uses a "client-side" approach. The hash calculation is performed entirely within your computer, and the file is never transmitted externally over the internet.
Q. What is the difference between SHA-256 and SHA-512?
A. SHA-256 generates a 256-bit (64-character) hash and is the most widely used standard today. SHA-512 generates a longer, 512-bit (128-character) hash, offering higher complexity and security. SHA-256 is recommended for most general purposes.
Q. Is there a fee to use the site?
A. The FreeImgFix hash generator is free for life. It is built with technology that avoids API call costs or server traffic fees, so no charges are passed on to the user.
