文本 & 工具 计算器

字数统计、字符统计、密码生成器等。

用于草稿、字数限制与安全习惯的文本指标与生成器,处理均在浏览器内完成。字词统计依赖分词规则,可能与发布系统不一致。密码生成器产生随机字符串,强度也取决于您如何保存以及是否在多站复用。随机数工具用于抽样与游戏,除非明确为密钥用途设计,否则不要用于生成加密密钥。

该选择哪个计算器?

以下逐一说明每个计算器的用途、前提与常见错误。先了解假设,再解读结果。

字符计数器

The Character Counter gives you a precise character count for any text, with real-time updating as you type. Toggle between counting with or without spaces, and check your text against common platform character limits: Twitter/X (280), SMS (160), Instagram bio (150), meta descriptions (155–160), and Google Ads headlines (30). Whether you're crafting the perfect tweet, writing SEO metadata, composing an SMS campaign, or filling out a form with a character limit, this tool ensures you stay within bounds.

密码生成器

The Password Generator creates cryptographically secure, random passwords tailored to your requirements. Choose password length (8–64 characters), and include or exclude uppercase letters, lowercase letters, numbers, and special characters. All generation happens entirely in your browser using the Web Crypto API — your passwords are never sent to any server, never logged, and never stored. Use the copy button to copy instantly. For maximum security, pair generated passwords with a reputable password manager rather than memorizing them or writing them down.

字数统计

The Word Counter instantly analyzes any text and gives you word count, character count (with and without spaces), sentence count, paragraph count, and estimated reading time. Paste or type your text and get results in real time as you write. Essential for blog posts with minimum word count requirements, college essays with strict word limits, SEO content that needs to hit 1,500–2,000 words, social media posts with character caps, and any writing task where length matters. Results update live — no submit button needed.
