Text to Base64 is a data encoding method that converts plain text (ASCII or Unicode) into Base64-encoded data. This allows smooth and safe data sharing between systems that only handle text.. This includes emails, APIs, and configuration files.
Base64 encoding does not compress or encrypt data. Instead, it offers a reliable way to show binary content, like images or files, as readable text. With this online tool, you can encode and decode Base64 instantly, right in your browser — safely and privately.
Convert Text to Base64 Instantly
Easily turn any text into Base64 without installing anything. Just paste your text, click Encode, and copy or download the output.
If you need the reverse process, switch to Base64 to Text to decode Base64 strings back into readable text.
This tool performs every operation locally in your browser — ensuring complete privacy and no data upload to servers.
How to Encode Text in Base64
Paste or type your text.
Click Encode to perform a fast text-to-base64 conversion.
Copy or download the encoded result.
To decode, paste a Base64 string and click Decode to restore the original text.
What Is Base64 Encoding
Base64 is a way to encode binary data as text. It uses 64 characters to represent this data in an ASCII string format.
People mainly use it to get help and protect data when sending binary information through text channels.
Not encryption – Base64 is reversible.
Not compression – It increases data size by about 33%.
Used for – Email (MIME), JSON payloads, APIs, and data URIs.
Utilize Base64 for safe data depiction, not for secrecy.
Why Use This Base64 Converter
🔒 100% Private: All processing happens locally in your browser.
⚡ Fast & Simple: Paste → Encode → Copy in seconds.
🔁 Two-way Conversion: Encode and decode on one page.
🧰 Smart Controls: Base64URL mode, MIME line wrap, padding toggle.
⌨️ Keyboard-Friendly: Optimized for quick repetitive use.
Where to Use Base64 Encoding
Embedding small images or icons as Data URIs in HTML/CSS.
Sending binary data safely inside JSON or API payloads.
Encoding attachments and inline content in emails (MIME format).
Debugging and inspecting encoded strings for data validation.
Tip: To handle images, use the Image to Base64 Converter, then decode or validate the output here.
Advanced Base64 Options That Matter
Base64URL: Use URL-safe encoding for JWTs or query strings.
Line Wrap (76 chars): Format output for MIME Support.
Padding Control: Add or remove “=” padding based on system requirements.
Charset Check: Convert to ASCII if the output looks corrupted.
Examples

Developer Shortcuts & Code
Python: quick tests with Python base64 encode / Python base64 decode, then verify here
macOS Terminal: base64 decode is built-in for fast round-trips
Simple obfuscation for demos: rot13 decoder / rot13 encoder (before or after Base64)
If a decode looks wrong, confirm code points by converting text to ASCII, then re-encode

Frequently Asked Questions
-
A binary-to-text encoding technique called Base64 transforms binary data into a string of ASCII letters. It is frequently used to transfer photos over the internet, store passwords, and encrypt email attachments. Although base64 encoding does not encrypt data, it offers a way to send and store binary data in a simple format for various platforms and systems to understand.
-
No, converting text to base64 does not encrypt data. It only encrypts data in a manner that enables secure transmission and storage.
-
Text security, file size reduction, platform compatibility, text retention, and quick and easy conversion are a few advantages of Text to Base64.
-
Text-based data can be encoded using Text to Base64 for safe transmission and storage. Emails, passwords, and pictures are frequently stored in them.
-
Yes, Text to Base64 has some drawbacks, such as larger files, a smaller character set, and no encryption.
-
Base64 is for support, not compression.
-
Yes. Paste the string and decode to get base64 to text. If it was originally binary (like an image), save the decoded bytes as a file instead of viewing them as plain text.
