About Base64
Base64 is a binary-to-text encoding format. It represents data using a restricted set of ASCII characters, making content easier to include in text-based formats and transfer between systems.
Common Use Cases
- Email Attachments
- Data URLs
- JSON / XML
- API Tokens
- Image Data
Private & Secure
Your content is processed locally in your browser.
Lightning Fast
Encoding and decoding happen without a server round trip.
Developer Friendly
Useful for data, APIs, debugging, and testing.
Works Offline
Once loaded, the text tool requires no upload.
Your content never leaves your browser. All text processing is local.

Using Base64 Encode / Decode with confidence

What this tool helps you do
Base64 represents binary bytes with printable text characters. It is useful when a text-only system must carry bytes, but it is encoding—not encryption—and anyone can decode it.
When it is useful
- Inspecting Base64 API fields
- Creating or reading data URLs
- Transporting small binary values in text
- Debugging encoded configuration data
A practical example
The UTF-8 text “Hello” encodes to SGVsbG8=. Decoding that value returns the original five characters.
Limitations and common mistakes
Base64 normally increases size by roughly one third. Do not use it to hide passwords or secrets. Text must be decoded with the same character encoding used before conversion.
Frequently asked questions
Is Base64 secure?
No. It is reversible encoding and provides no confidentiality.
Why does my value end with equals signs?
The equals signs are padding used to complete the final encoded group.
