Random base64 generator

World's simplest base64 tool

This online program generates random valid base64 data of constant or variable length. You can control the total number of base64 data pieces in the output and also enable multi-line (chunked) base64 output. Additionally, you can create full base64 strings that don't contain the padding character "=". Created by encoding gurus from team Browserling.

Base64 Length
Minimum number of characters in the generated base64.
Maximum number of characters in the generated base64.
To generate constant length base64, enter the same value in the min and max fields.
Count and Padding
Generate this many random base64 strings.
Generate full 24-bit base64 bundles that never have the padding character "=".
Base64 Chunking
Output random base64 in chunks on multiple lines with constant line length.
Length of each chunk. (Note: the last line can be shorter if there is not enough data.)
Random base64 generator tool What is a random base64 generator?
This application works in your browser and it creates random base64 data pieces. The base64 encoding alphabet consists of 64 ASCII characters – 26 of which are small English letters (a, b, c, … z), 26 are capital English letters (A, B, C, …, Z), 10 are digits (0, 1, 2, …, 9), 2 are special characters "+" and "/", and 1 is trailing character "=". All base64 strings that the program generates are valid base64 and can be decoded. You can change the length of output base64 by adjusting the minimum and maximum range options. As base64 consists of bundles of 4 characters, the range of the output data length must contain at least one value that is a multiple of four. When decoded, every 4 base64 symbols turn into to 3 regular symbols. Sometimes, there are one or two "=" characters at the end of the base64 data. This means there were not enough bits in the encoded data and the missing bits were filled with the equal sign. If you want the generated base64 to have full groups of bytes, then use the "Avoid Padding" option. In the output, you can have as many base64 strings as you want and you can control it via the count option. If the base64 data is really long, you can also split it into multiple chunks by selecting the "Chunkify Output" option and specifying the desired chunk length. Base64abulous!

Generate Random Base-64
In this example, we generate fifteen random base-64 data pieces of different lengths. We set the minimum length to 8 and the maximum to 60. Since the length of base-64 is always a multiple of 4, the generated data is always either 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, or 60 characters long.

Fixed Length Base-64
In this example, we fix the base-64 length to 24 characters and create 12 random base-64 strings. To fix the length, we set both min-length and max-length options to 24, and to output 12 different base-64 strings, we set the count option to 12. We also enable the option to avoid the padding symbol "=". With this option turned on, the base-64 data always forms complete groups of 4 bytes.

Multi-chunk Random Base64
This example formats the generated base-64 data into short constant-length multi-line blocks. To do this, it uses the "Chunkify Output" option and sets the number of characters per line equal to 12. It generates four random base-64 data blocks of random length with 36 to 48 characters in each piece. In the chunkified output, there are always 3 or 4 lines per block (because 36/12 = 3 and 48/12 = 4).
