How to use Base64 encode/decode
Encode and decode Base64 for APIs, config files, email headers and data URIs. Text is handled as UTF-8, so Bangla and emoji round-trip correctly instead of turning into question marks. You can also turn any file into Base64, or decode a Base64 string back into a downloadable file.

Base64 encode/decode: common questions
Why does decoded Bangla text show as garbage on other sites?
Many tools decode bytes as Latin-1 instead of UTF-8. This tool encodes and decodes text as UTF-8, so Bangla comes back exactly as it was.
What is URL-safe Base64?
It uses - and _ instead of + and / and drops the = padding, so the result can go into a URL or file name. The decoder accepts both styles.
Is Base64 encryption?
No. Base64 only changes how data is written, and anyone can decode it. Don't use it to hide passwords or secrets.
