Convert Base64 to Integers

Need to turn a Base64 string into a list of integers? The Convert Base64 to Integers tool makes that easy. Just paste in your encoded text, and it decodes it, grabs each character, and converts it into its numeric value live, right in your browser. You control the format, sort order, and duplication handling.

What Convert Base64 to Integers can do:

This tool decodes a Base64-encoded string, then converts every character into its Unicode integer (char code). It lets you format the results however you want and optionally sort or deduplicate the list. It works entirely in your browser, so it’s private and fast. You’ll see live updates every time you change something no reloading needed.

Example:

Input:
SGVsbG8gV29ybGQh

Decoded:
Hello World!

Output:
72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33

Common Use Cases:

Use it to inspect Base64 output, generate integer-based representations for encoding experiments, or decode values before feeding them into other systems. It’s great for testing, reverse-engineering, or just learning how encoding works. No fluff just results.

Useful Tools & Suggestions:

Once you’ve used Convert Base64 to Integers, try Convert Integers to Base64 to make sure the encoding and decoding flow works both ways. And if you’re working with mixed formats, Extract Integers from Data helps isolate clean values before conversion.
