Free Base64 to Text
Base64 strings look like gibberish until you decode them. Paste any Base64-encoded value here and this free decoder converts it back to readable text with full Unicode support — validating the input first so you get a clear error instead of mojibake.
How to Use the Base64 to Text
- Paste your Base64 string into the input box.
- Click “Decode Base64”.
- Read the decoded text, or see a clear error if the input is invalid.
- Copy or download the result.
Features
Strict Base64 validation before decoding: the tool checks the character set and padding, then decodes as UTF-8 so international characters and emoji come through correctly. Malformed input produces a plain-English explanation of what is wrong instead of garbled output. One-click copy and .txt download are built in.
Benefits & Use Cases
Developers decode API tokens, JWT payloads and data URIs while debugging. Security learners inspect encoded blobs from tutorials and challenges. Anyone who received an encoded string in an email or config file can reveal its contents without installing anything or pasting secrets into a random server.
Tips
Base64 length must be a multiple of 4 — if yours is not, a character may have been cut off when copying. Whitespace is ignored, so you can paste wrapped or multi-line Base64 safely. If decoding succeeds but the text looks like binary garbage, the original data probably was not text (e.g. an image).
Frequently Asked Questions
Is the Base64 decoder free?
Yes, completely free with no limits and no sign-up.
What does “Invalid Base64” mean?
The input contains characters outside the Base64 alphabet (A–Z, a–z, 0–9, +, /) or has bad padding. Double-check what you pasted.
Does it support Unicode and emoji?
Yes. It decodes the bytes as UTF-8, so accented characters, CJK text and emoji all decode correctly.
Is it safe to decode secrets here?
Decoding happens 100% locally in your browser, so pasted values never leave your device. Still, treat decoded secrets carefully.
Can it decode Base64 images?
It decodes to text. If the Base64 was an image, the bytes will not form valid UTF-8 text and you will see an error — that is expected.
