For example, by entering "32-64", the program will generate bytes from 32 to 64 (both inclusive). To create your own range of bytes, use the custom range mode, and enter the necessary bytes in the field below. The other range categories are Low Nibbles (bytes from 0 to 127), which have the lower end set, High Nibbles (bytes 128-255), which have the higher end set, Full Bytes with all bits set (0xFF), Null Bytes with no bits sets (0x00), the C0 ASCII Control Chars (0-31 and 127), C1 Extended ASCII Control Chars (128-159), Printable ASCII Chars (32-126), Lowercase Chars (97-122), Uppercase Chars (65-90), Digits (48-57), Punctuation Chars (33-47, 58-64, 91-96, 123-126), Single Bits (0 and 1), and Powers of Two (bytes 1, 2, 4, 8, 16, 32, 64, 128). The first (and default) byte range includes all 8-bit bytes from 0 (0x00) to 255 (0xFF). By choosing one of the predefined byte ranges, the random byte selection algorithms will pick bytes only from the selected range. To quickly generate files with different content, the app is equipped with a predefined byte range selection list. The contents of the file can also be adjusted in the options. You can also specify the file length in kilobytes (for example, "8k" or "8kb") and in megabytes (for example, "2m" or "2mb"). The file size can be configured by entering an integer (such as "32") or a number with the prefix "b" (such as "32b") in the file length field. The needed file size can be set in the options. This online program creates random binary files of any size.
