Huge update!! This converter now supports file input! Previously, you could only type text into the converter, but now you can click the file upload button located at the top of your screen and see your PDFs, images, and other files represented in a base64 format for channels that only support text. The best part about this update is that it works locally, meaning your computer does all the processing of your files so your files never leave your computer. This is why the converter will still work if you lose internet connection and the page is still open. If you want to give feedback use the suggestions!
Base64 is a way of encoding binary data (such as images or documents) into text that can be easily transmitted over channels that only support text, such as email or web pages. It works by dividing the binary data into chunks of 6 bits and mapping each chunk to one of 64 characters, such as A-Z, a-z, 0-9, + and /. Sometimes, the encoded text needs to be padded with one or two = signs at the end to make it a multiple of four characters.
For example, the word "Man" in ASCII is 01001101 01100001 01101110 in binary. This can be divided into four chunks of 6 bits: 010011, 010110, 000101 and 101110. These chunks correspond to the Base64 characters T, W, F and u respectively. So the Base64 encoding of "Man" is "TWFu".
