Frequently asked questions

Does this tool upload my text? No. All conversion happens locally in your browser. Your text never leaves your device.

What is the difference between ASCII and decimal codes? ASCII defines a mapping between characters and numbers; this tool outputs those numbers in decimal (base-10) form, which is the most human-readable representation.

What format should decimal input be in? Decimal numbers should be separated by spaces. Each number is read as a base-10 integer.

Is there a length limit? The only limit is your browser's available memory. Even very long texts convert instantly.
