About the Base64 Decode
Base64 represents binary data using 64 plain ASCII characters, so it can travel safely through text-only channels — data-URI images, JSON payloads, email and tokens like JWTs. This Base64 Decode is UTF-8 safe, so accented letters, non-Latin scripts and emoji round-trip correctly.
Everything runs in your browser, so the text you encode or decode never leaves your device — fine for sensitive snippets. Remember Base64 is encoding, not encryption: it makes data text-safe, not private.
Frequently asked questions
Is Base64 encryption?
No — Base64 is encoding, not encryption. Anyone can decode it back instantly, so never use it to hide passwords or secrets.
Is my text uploaded?
No. The Base64 Decode runs entirely in your browser, so your text never leaves your device.
Does it handle emoji and non-English text?
Yes. Encoding and decoding are UTF-8 safe, so accented letters, non-Latin scripts and emoji round-trip correctly.
What is URL-safe Base64?
URL-safe Base64 swaps + and / for - and _ and drops the padding, so it is safe in URLs and filenames. Toggle it on when encoding.
