To encode a PDF file to Base64 you have to read all file bytes and encode them to Base64 using the Base64.Encoder class. Please keep in mind, that the example below prints the Base64 string to console, so use only small PDF files for tests or write the output into a text file.

If you do not know what output format you need, check the following examples to see how will look the result of the same Base64-encoded file formatted in each of the available formats (as an example file I use a gzipped text file):

The readAsDataURL method is used to read the contents of the specified Blob or File. When the read operation is finished, the readyState becomes DONE, and the loadend is triggered. At that time, the result attribute contains the data as a data: URL representing the file's data as a base64 encoded string.

So now we have converted our file to Base64 string and pushed it inside the myFiles object. every time our input get changes, myFiles is going to erase all the data it holds and will process everything again.

So in that case, we want to check if input has single or multiple files, if it has single file we want to name it right according to input name, in our example it would be picture but if it has more than one file, we are going to name with file lengths such as picture[0], picture[1]

Uploading files to APIs like MailSlurp's typically involves sending a file as a base64 encoded string to a server as the text/plain body of an HTTP POST request. Converting a file to a base64 string means reading a file into a byte array and then encoding the byte array into a string using base64 encoding.

Transferring an ASCII file over the network can cause corruption if not decoded correctly. The reason is ASCII files are string converted to bytes, and when those bytes are decoded incorrectly back to ASCII your data becomes corrupt.

The following code reads a Base64 Encoded file on the disk (decoding it in the process) and then re-encodes the file into base64, writing those bytes to the first socket connection the ServerSocket receives.

For comparison, here is how to encode a file into base64 without using streams.Note this will not scale well as it can consume large amounts of memory if you are converting a large file.

Hello Eng Swee Yeoh,I have a similar urgetn requirement in my current project , where i have to read zipped base64, csv file and convert it to xml .Can you please help me with the java mapping code where after unzipping you get a csv file and then convert the csv file to xml .
