Super Fast Base64 Encode Decode Tool/Editor for Windows

Free Hex Editor

Free Hex Editor is a tool that can open any file in their raw format, examining the bytes (hexadecimal values) that make up the file. The tool is written in C++ make it super fast to open large files. 

You can edit inspect system files, disks, disk images, memory, and log files; patch errors, and examine disk structures. Be cautious with this tool! Changes are irreversible. 

With new Version 1.7.3.+ supports Base64 encoding and decoding - Get it here.  

Need lightning fast Base64 encoding and decoding feature with MIME image support in an actual downloadable Windows executable?  

With this tool you can Base64 encode and decode any file. However, Image files with extensions (.BMP, .GIF, .ICO, .JPEG, .JPG, .PNG, .SVG., .TIF, .TIFF, .WEBP) will included the proper Multi-Purpose Internet Mail Extension (MIME) type for those supported images. So supported  images will be Base64 encoded with following prefix in the file export.

Take for example a Base64 encoded .PNG will look like; 

data:image/png;base64, iVBORw0KGgoAAAA ...

Other of image types examples are image/jpeg, image/png, and image/svg+xml.

For the uninitiated, MIME is type of Internet standard originally developed to allow the exchange of different types of data files through e-mail messages, and used to set "Content-Type:" as well.  Some refer to this as a 'media type' or MIME type is a standard that indicates the nature and format of a document, file, or assortment of bytes. It is defined and standardized in IETF's RFC 6838.

The above will export a 10-tooth-black-gear.b64. Opening the file in Frhed you get MIME type with base64 encoded file.

Importing the MIME encoded file, Frhed will convert the file into proper image extension
