Base64 splitter

World's simplest base64 tool

This online program chunkifies single-line base64 data into multi-line base64 chunks. It also works with base64 data URI schemes and you can set the length of each output line. Created by encoding gurus from team Browserling.

What is a base64 splitter?

learn more about this tool

This application works in your browser and it splits the input base64 string into fixed length lines. The default line length is 76 characters, which is the maximum line length of MIME (Multipurpose Internet Mail Extensions) specification but you can also use longer lines. Usually, the length should be a multiple of 4. If you have never heard about base64 before then it's a binary-to-text encoding that encodes 6 bits of binary data in an 8-bit Latin-1 character. The base64 encoding is also sometimes called radix64 representation. As an extra feature, we have added an option to change the chunk separator. It's the newline character \n by default but if you need space-separated or comma-separated base64 chunks, then just enter the character that you need in the output chunk separator option. Base64abulous!

Base64 splitter examples

Click to use

Chunk Length 24

In this example, we separate a long base-64 text into a series of shorter 24-character base-64 snippets with one snippet per line. The splitting is performed by simply counting characters and inserting a newline symbol after every 24 symbols. Both input and output are valid base-64 data.

Required options

These options will be used automatically if you select this example.

Chunk length Line length of chunks.

Chunk separator Separate chunks with this char.

Remove the Data URI

This example sets the line length to 0, which means that the input base-64 data will be passed through and won't be chunkified. It also enables the option that removes the data URI from the input string, so effectively this example gets rid of the data URL signature at the beginning of base-64.

Weird Base64 Chunks

In this example, we create weird base-64 chunks. First of all, the line length is set to 3, which isn't usually allowed as 3 characters are 18 binary bits (there are 6 bits of binary information in one base-64 character) and 18 bits don't evenly split into bytes of 8 bits. Second, the chunks are separated by exclamation points, which will make every computer scientist mad.
