Base64 Encode/Decode
Encode text to Base64 or decode Base64 back to UTF-8 text for data URLs, APIs, and configs.
Open Base64 Encode/DecodeText Tools
Counters, formatters, encode/decode, case, lines.
Count words and lines, change case, encode or decode text, format JSON, and more. Built for writers, developers, and anyone who works with plain text. Fast and private.
This category is for anyone who works with plain text or code: writers, developers, and support staff. Tools cover counting, encoding, formatting, and related utilities that stay on-device.
Common tasks include counting words or characters for publishing limits, encoding or decoding URL parameters, working with Base64 for data URLs or APIs, and pretty-printing JSON during debugging. Processing is local so drafts and tokens are not uploaded for the core transform.
Pick by task: word/character count and reading time, URL or Base64 encode/decode, or JSON format. Pair these with the Word Counts guide when you need editorial context beyond the live count.
Be careful pasting secrets into any browser tool on a shared computer. Prefer local/offline workflows for production secrets even though Vastorae’s transforms are client-side.
