無料オンライン文字カウンター

Yes, the 文字カウンター on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.

No installation needed. The 文字カウンター runs entirely in your web browser on any device — desktop, tablet, or mobile.

Completely safe. The 文字カウンター processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.

The 文字カウンター has no hard character limit — it processes text as large as your browser can handle, typically hundreds of thousands of characters. Very large inputs may be slower depending on your device.

Yes. The 文字カウンター handles all Unicode text correctly, including accented characters, CJK characters, Arabic, Cyrillic, and emoji. It works with any language that your browser renders, with no additional setup or language packs required.

Yes. The 文字カウンター is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.

Select and copy the result text to paste into any document or app. For image tools, a Download button saves the file directly to your device. Your browser's built-in screenshot function also captures results quickly. No account or login is required.
