❓ FAQ
What is URL-safe
Base64?+
URL-safe Base64 (Base64URL) replaces + with - and / with _, and removes
padding =. This makes it safe for URLs without additional encoding.
How do I encode Base64 in
Python?+
Use: import base64; base64.b64encode(text.encode()).decode(). For URL-safe,
use base64.urlsafe_b64encode().
Can I encode multiple
strings at once?+
Yes! Switch to "Batch Mode" and enter one string per line. Each line will be
encoded/decoded separately.
Why does Base64 make data
33% larger?+
Base64 uses 4 characters to represent 3 bytes of data (4/3 ≈ 1.33). This is
the trade-off for safe text-based transmission.
Is my data
secure?+
Yes. Everything runs 100% in your browser. No data is ever sent to any
server.
