Frequently Asked Questions

The Word Counter tokenizes text based on whitespace and standard word boundary punctuation. Hyphenated words (e.g. self-hosted) are counted as a single word by default, while numbers are included in the word count if they are separated by spaces.
Absolutely not. All text processing is executed completely within your browser's local sandbox environment (via the V8 JavaScript engine). No data is transmitted over the network, ensuring complete confidentiality.
The tool can easily handle up to 5MB of plain text (approx. 800,000 words) without performance lag. Paste amounts larger than this might exceed typical browser tab memory allocations.
No. Standard hyphenated terms are counted as a single word to align with common publishing and academic word counting guidelines.
Yes, the Word Counter supports Unicode text and can count words in Spanish, French, German, and other space-separated languages. For languages like Chinese or Japanese that do not use spaces, character counting is recommended.
