📘 About the Base64 Encoder
Base64 turns any data into plain letters, digits, + and /, so it can travel in email, JSON, URLs and HTML. Type text to encode it, switch to Decode to read Base64, or choose a file or image to get a data URI you can paste into HTML or CSS.
Text is handled as UTF-8, so Hindi, other Indian scripts and emoji encode and decode correctly.
💡 How to use the Base64 Encoder
Type or paste text, or choose a file.
Pick Encode or Decode, and URL-safe if needed.
Copy the result.
❓ Frequently asked questions
Is Base64 encryption?
No. Anyone can decode Base64 — it is an encoding, not a way to hide information.
Why is Base64 bigger?
It uses 4 characters for every 3 bytes, so the output is about 33% larger than the input.
