How to Use
- Paste/Type your text into the large textarea.
- Toggles (counting rules)
- Trim ends: removes leading/trailing whitespace before counting.
- Exclude spaces: ignores half/full-width spaces and tabs for JP character count.
- Exclude newlines: ignores line breaks for JP character count.
(“Total characters (incl. spaces/newlines)” always uses the raw string)
- Read the live metrics in the grid:
- JP characters (with settings applied)
- EN word count
- Total characters (incl. spaces/newlines)
- Lines
- Reading time (estimate)
- UTF-8 bytes
Outputs / Results
- Effective JP character count (reflecting your space/newline rules)
- English word count for mixed-language text
- Raw total characters including spaces and line breaks
- Line count based on newline characters
- Estimated reading time using:
- JP: 400 chars/min
- EN: 200 words/min
(added together for mixed text)
- UTF-8 byte size for storage/transport sizing
[Completely Free] Utility Tools & Work Support Tools
You can use practical tools like CSV formatting, PDF conversion, and ZIP renaming entirely in your browser, all for free. Each tool page clearly explains “How to use it”, “What the output looks like”, and “Important notes & caveats”, so even first-time users can start without confusion.
Notes / Caveats
- Shadow DOM isolation: page-level CSS/JS cannot style or access the widget internals.
- Word-count regex: counts
[A-Za-z]+as words, treating apostrophes and hyphen-joined tokens (e.g., don’t, state-of-the-art) as single words. Case-insensitive. - JP character count: surrogate pairs and combining marks are treated as characters (browser-dependent edge cases may exist).
- Scope of toggles: space/newline rules affect JP characters; Total characters is always from the raw text.
- Reading time is an estimate and varies by audience and style.
- UTF-8 bytes follow
TextEncoder. Emojis/compound glyphs increase byte length. - No built-in copy/save buttons: use your browser’s standard copy or save features if needed.
