Encoding
Base64 Encode
Convert plain text into Base64, the encoding used to embed binary or arbitrary data inside URLs, JSON values, JWTs, and HTTP headers without breaking the surrounding format.

Introduzione allo strumento
Convert plain text into Base64, the encoding used to embed binary or arbitrary data inside URLs, JSON values, JWTs, and HTTP headers without breaking the surrounding format.
Panoramica dello strumento
Base64 represents arbitrary bytes using only 64 ASCII characters (A–Z, a–z, 0–9, +, /, plus = padding). It exists because many transports — HTTP headers, JSON strings, URLs, email — assume printable text. Encoding makes any input safe to drop into those contexts; decoding reverses the operation. Base64 is encoding, not encryption: anyone with the encoded string can decode it.
Casi d'uso
- Use Base64 Encode when you need fast encode plain text into base64.
- Handle encoding workflows directly in the browser with no install required.
- Support SEO long-tail intent by covering quick checks, troubleshooting, and one-off conversions.

FAQ
Does Base64 encrypt my data?+
No. Base64 is a reversible encoding, not encryption. Anyone with the Base64 string can decode it.
Why is the output about a third larger than the input?+
Base64 packs every three bytes of input into four output characters, so the output grows by roughly 4/3.
What characters does Base64 use?+
Standard Base64 uses A–Z, a–z, 0–9, plus + and /, with = as padding so the output length is a multiple of four.
