Is the base64 to text decoder private?
Yes. The decoded bytes are interpreted as UTF-8, making the tool suitable for multilingual text, JSON, XML, and source code. All processing happens locally in your browser — nothing is uploaded to our servers.

Built for Base64 text
The decoded bytes are interpreted as UTF-8, making the tool suitable for multilingual text, JSON, XML, and source code.
No registration, watermark, queue, or server upload is required.
Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
What encoding is used when decoding to text?
Bytes are interpreted as UTF-8, which covers most modern text, JSON, XML, and source code.
Can I decode Base64URL text values?
Yes. URL-safe characters and missing padding are normalized automatically before decoding.
When should I use Base64 for Base64 text?
Use it when a text-only channel or API must carry binary data, or when a small Base64 text asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
