About Word Counter
Last updated: May 2026
OptiPix 字数统计器是一款全面的文本分析工具，可即时提供您输入的统计数据。实时统计字数、字符数（含空格和不含空格）、句子数、段落数、行数和音节数。获取阅读和朗读时间估算、Flesch 阅读易读性和 Flesch-Kincaid 年级水平的可读性分数，以及包含停用词过滤的十大关键词密度分析。使用平台预设，如 Twitter (280 字符)、Instagram (2200 字符)、LinkedIn (3000 字符)、Meta 描述 (160 字符)、标题标签 (60 字符) 和 SMS (160 字符)，以确保您的内容符合限制。当您超出上限时，字符限制检查器会变为红色。您还可以为任何平台设置自定义限制。拖放 .txt 文件即可立即分析。将文本复制到剪贴板或下载为 .txt 文件。所有计算均在您的浏览器中 100% 运行 - 您的文本绝不会发送到任何服务器，使其成为最私密的在线字数统计器。
How It Works
该工具使用 JavaScript 字符串操作，通过空格（单词）、标点符号（句子）、双换行符（段落）和单换行符（行）来分割文本。音节是通过计算元音组合来估算的。可读性分数使用基于单词、句子和音节计数的 Flesch 公式。
