Encoding Tools
Move binary-safe text through JSON, query strings, and logs with Base64, percent-encoding, UTF-8, and hex helpers. MD5 is listed for checksums with clear non-security guidance.
Base64 is encoding, not encryption — anyone can decode it. URL encode/decode is for query and path components. UTF-8 and hex help when you need to inspect bytes. Prefer a real password hash library for secrets; MD5 here is a quick fingerprint only.
Paste small samples first. Megabyte files can freeze a tab even though nothing is uploaded.

Frequently asked questions
Is Base64 encryption?+
No. It is reversible encoding. Use TLS and real crypto libraries for confidentiality.
Should I store passwords with MD5?+
No. Use a modern password hash (Argon2, bcrypt, scrypt). MD5 here is for quick checksums only.
