Character Frequency Counter

It counts every individual character in your text, including letters, numbers, spaces, punctuation, newlines, and tabs. Special characters like newlines and tabs are labeled as (newline) and (tab) in the output.

The table shows up to 100 unique characters, sorted by frequency (most common first) or alphabetically. Click the "Char" or "Count" column headers to toggle sort order.

The counter uses JavaScript's string iteration which operates on UTF-16 code units. Most characters (including emoji that are a single code point) are counted correctly. However, complex emoji using ZWJ sequences (like family or skin-tone emoji) may be split into multiple characters in the count display.

No — the counter tallies every character present in the input. To exclude specific characters, pre-process your text: remove them using Find & Replace or the Whitespace Trimmer (for spaces/newlines) before pasting into the counter. You could also export the results and filter the table externally in a spreadsheet.

Each character's percentage is calculated as (character count / total character count) × 100. The percentages sum to 100%. The bar visualization uses the percentage relative to the most frequent character, so the most common character always shows a full-width bar for easy visual comparison.

Common uses include analyzing ciphertext patterns, checking encoding distributions, examining language character usage, or debugging text processing issues where unexpected characters may have crept in.
