# Base64 chunk joiner

World's simplest base64 tool
This online program merges multiple base64 chunks into a continuous base64 string. It accepts multi-line base64-encoded data and lets you customize the merging format. Created by encoding gurus from team Browserling.

## What is a base64 chunk joiner?

learn more about this tool
This application works in your browser and it converts multi-line base64 chunks into a single long base64 chunk. By default, the options are configured so that the input base64 data has one chunk per line and the output base64 is glued together via the empty join character so that it forms single-line output. If you change these options, you can customize the input chunk separator symbol and the output data join symbol. For example, if the input base64 pieces are separated by a tab character, then you can match it by entering the symbol "\t" in the input delimiter field; if the input text is dash-delimited, use a "-" symbol as the separator. Similarly, you can change the join character to any other symbol (or multiple symbols). For example, if you set it to a space, you'll get space-joined base64, or if you set it to a dot, then you'll get dot-separated base64. Additionally, you can quickly delete the data URL scheme prefix from the joined base64 string. Base64abulous!

In this example, we load multi-line base-64 data in the input field and we convert it to fit on just one line in the output. To merge all base-64 pieces together, we set the character "\n" as the input delimiter and we leave the output delimiter field empty. In this case, no symbols get added between the output base-64 pieces and we get a single line of data in the output.

**Required options**

Enter the input chunk
separator symbol.
(By default, it's a line break.)

When printing the output base64,
glue the extracted base64 chunks
together via this character.
(By default, it's an empty symbol.)

data URL prefix in the
joined base64.

Join Tab-separated Base64

The input base-64 value in this example is tab-delimited. Each chunk is 4 characters wide and the input also contains the data URL scheme. To match the input chunk separator, we enter the value "\t" in the input separator option. We glue the chunks together through the empty character and also remove the URI prefix from the beginning of the data.

Replace Chunk Separator

In this example, we show another application of this program. Instead of connecting all base-64 pieces, we replace the separator between them. In the input, the chunks are separated by the symbols "_#_" but in the output we set the separator to the "!" symbol.
