Frequently Asked Questions

What is Base64 encoding used for?

Base64 encodes binary data into ASCII text using 64 characters (A-Z, a-z, 0-9, +, /). It is commonly used to embed images in HTML/CSS, transmit data in URLs, and store binary values in JSON.

Is Base64 encryption?

No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 — it is meant for data transfer, not security. Never put secrets in Base64 expecting them to stay hidden.

Why does the decoded text show garbled characters?

The input may not be valid Base64, or the original data was binary (like an image) rather than text. This tool handles UTF-8 text; for binary data use a dedicated file encoder.
