Base64 to Text

What you can do

• •Clear validation errors

How it works

1. 1

   Paste the Base64 string

   Whitespace-tolerant enough for typical copy-paste from docs.

2. 2

   Decode

   Valid Base64 becomes UTF-8 text. Invalid padding or characters surface as errors.

3. 3

   Copy the decoded text

   Keep the result on this device — nothing is uploaded.

Common uses

• •Decode a Base64 snippet from logs or docs
• •Verify a Text to Base64 round trip
• •Inspect a token that should be readable UTF-8

Frequently asked questions

What happens if the Base64 is invalid?

You get a validation error instead of mojibake. Fix padding or illegal characters and try again.

Does this decode binary files?

It decodes to UTF-8 text. Binary payloads that are not valid text may not display as intended.

Is decoding uploaded?

No. Base64 is decoded only in your browser.
