About DevToolbox - 开发者工具箱

DevToolbox is a privacy-friendly, all-local developer toolkit. It opens as a floating panel on the current page and provides QR code generation, Base64 and URL encoding, hash/HMAC, timestamp conversion, JSON formatting, RSA and DES encryption, UUID/JWT/regex tools, color tools, radix conversion, text utilities, page screenshots, copy-unlock, image editing with pixel measurement, and PDF tools. All processing happens locally in the browser. No files, page content, keys, or settings are uploaded to a server.
