Encode, decode and transform text without sending it to a server. These tools run entirely in your browser, which matters most when the text is a token, a password hash or a piece of code you do not want logged anywhere. The first live tools are the Base64 Encoder and Base64 Decoder: both are UTF-8 safe, so Bangla text, emoji and accented characters survive the round trip exactly, and the encoder offers a URL-safe variant for links and query strings. Later batches add URL encoding, HTML entities, hex converters, Morse code, Caesar and ROT13 ciphers, JWT decoding and hash generators from MD5 to SHA-512. Every tool shows its result instantly and copies with one click, with no account and no upload. If you work with APIs, the JSON Formatter in Developer Tools pairs naturally with these encoders for inspecting payloads. Each tool explains what its encoding does in plain language, so beginners can learn while they work. And because nothing leaves your browser, you can safely encode test data, tokens and internal strings.

About this category

When will these tools be ready to use?

Tools are published in batches, starting with the 40 highest-value tools in Phase 1. Each tool goes live only when it is fully working, tested on mobile, and has its own written guide.

Will my files be uploaded when I use a tool?

No. Every Toolsvine tool runs 100% in your browser. Files, text and images you use in a tool never leave your device.
