AI 教程

編碼 / 解碼

支援 Base64、Hex、URL、HTML 及自訂轉換。

支援 Unicode,轉換後結果會自動更新。

Tool overview

Swap between Base64, Hex, URL, and HTML encodings right inside the browser, perfect for prepping payloads or sanitizing user input.

Example: convert a JSON payload to Base64 before embedding it in an Authorization header or query string.

Tip: decoding ignores invalid characters, so verify the string’s integrity before sending it out.

Hash 雜湊

使用 Web Crypto API 即時產生 SHA-1 / SHA-256 / SHA-384 / SHA-512。

Tool overview

Generate SHA-1 / SHA-256 / SHA-384 / SHA-512 digests with Web Crypto to verify content integrity or compare tokens between environments.

Example: compute SHA-256 for your release bundle and confirm it matches the checksum published elsewhere.

Tip: trim whitespace and let Web Crypto finish before copying the hash, as larger inputs take longer to digest.

JSON 工具

格式化、壓縮與驗證,支援帶逗號的結構。

Tool overview

Tool overview

Format, minify, and validate JSON payloads to keep APIs readable and catch stray commas before copying them elsewhere.

Example: paste a webhook response to format it for documentation and check for trailing commas.

Tip: validation surfaces parse errors so you can spot invalid structures early.

時間轉換

兼顧 ISO/Unix/在地與常見時區顯示。

Unix ms -> 時區

Tool overview

Convert between ISO, Unix, and local timestamps while comparing common zones like Taipei, Beijing, Berlin, and Tokyo.

Example: set 2026-03-16 09:00 and verify how it looks in UTC, Berlin, and Tokyo for deployment windows.

Tip: pick IANA zones such as Asia/Shanghai for Beijing or Asia/Tokyo for Japan, or keep `local` to reflect your browser clock.

Regex 工具

測試正則、呈現 match/replace 與捕捉群組結果。

Matches

Capture groups

Tool overview

Input regex pattern and target string to list matches, replace input, and explain capture groups.

Example: capture HTTP header fields and replace them before logging.

Tip: enable g when you expect multiple matches.

文字格式化

大小寫、Slugify、列數統計與行尾清理。

Tool overview

Transform case, slugify, and trim line endings to polish copy before sending it out or embedding it in docs.

Example: convert a headline to Title Case for a doc or Slugify it before embedding in a URL.

Tip: `Trim lines` removes trailing whitespace from each line so pasted text stays clean.
