How the result is calculated
The browser reads the selected image bytes and represents every six input bits with a Base64 character. Base64 increases the encoded size by roughly one third and does not compress the image.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
Important limitations
Results are provided for convenience and should be checked independently before an important decision. A format or checksum result never authenticates an identity, document, account, licence, vehicle or registration.
