Encode text to Base64 or decode Base64 back to text (UTF-8 safe). How it works: Enter or paste your text or Base64 string into the input field. Select 'Encode' or 'Decode' based on your requirement. Choose UTF-8 or URL-safe mode from the dropdown if necessary, especially when working with non-ASCII characters or JWT tokens.
About the Base64 Encode / Decode
Base64 Encode / Decode is a free online tool that converts plain text to Base64 strings and vice versa, supporting full UTF-8 characters, including Hindi and emojis.
Use this tool when you need to embed data in URLs, create JWT tokens, or debug encoded strings from APIs, such as decoding a Base64-encoded JSON payload from an API response, like ₹ payment details or UPI transaction IDs.
The tool applies the standard Base64 algorithm with JavaScript's built-in btoa and atob functions, ensuring accurate conversions and privacy since all processing happens in your browser, without uploading any files.
The Base64 Encode / Decode is part of the free News Appite toolkit at news.appite.in — the same utilities our newsroom uses every day to check numbers, pages and files before publishing. There is no sign-up, no daily limit and nothing you enter is stored.
How to use the Base64 Encode / Decode
- Enter or paste your text or Base64 string into the input field.
- Select 'Encode' or 'Decode' based on your requirement.
- Choose UTF-8 or URL-safe mode from the dropdown if necessary, especially when working with non-ASCII characters or JWT tokens.
- Click the 'Convert' button and copy the result from the output area.
Tips & benchmarks
- Always enable URL-safe mode when decoding JWT tokens to avoid errors, especially when working with sensitive data like passwords or GST numbers.
- For maximum accuracy with non-ASCII text, enable UTF-8 mode before encoding, to ensure correct representation of characters like Hindi fonts or emojis.
- First, encode binary files locally as Base64 before pasting them for decoding, to avoid any potential issues with file uploads or processing.
- Never share Base64 strings containing sensitive passwords; Base64 is not encryption, it's just an encoding scheme, so keep your data secure with proper encryption methods.
- You can process multiple lines at once; each line will be encoded or decoded separately, making it easier to work with large datasets or multiple inputs.
Frequently asked questions
Is Base64 encryption secure?
No, Base64 is not encryption, it's an encoding scheme. It's used to represent binary data in a text format, but it does not provide any security benefits. You should use proper encryption methods to keep your data secure.
How does Base64 encoding work?
Base64 encoding works by converting binary data into a text format using a 64-character alphabet. This allows binary data to be represented in a text format, making it easier to transmit and store.
Can I encode binary data with this tool?
Yes, you can encode binary data with this tool, but you need to convert it to a text format first. You can do this by encoding the binary data as Base64 locally before pasting it into the tool.
Is my input safe from XSS attacks?
Yes, your input is safe from XSS attacks. The tool processes all input in your browser, without uploading any files or sending data to our servers. This ensures that your input remains private and secure.
What happens if I paste an invalid Base64 string?
If you paste an invalid Base64 string, the tool will attempt to decode it, but may produce incorrect results. You can try re-encoding the original data to ensure it's in a valid Base64 format.
Can I use this tool for Base32 or Hex encoding?
No, this tool is specifically designed for Base64 encoding and decoding. If you need to work with Base32 or Hex encoding, you'll need to use a different tool or library.
Is the Base64 Encode / Decode on News Appite free?
Yes. Every tool on News Appite (news.appite.in) is completely free for personal and commercial use, with no account, no watermark and no usage cap. Found a bug or want a new feature? Email contact@appite.in.
Can I use this tool to encode images to Base64?
Yes, you can use this tool to encode images to Base64 by first converting the image to a text format, but the tool itself only supports encoding plain text to Base64 strings and vice versa, so you would need to use another tool or method to convert the image to text first.
What does Base64 encoding mean?
Base64 encoding is a process of converting plain text to a Base64 string, which is a standard algorithm for encoding binary data as text using only 64 characters, making it safe for use in URLs, APIs, and other applications.
Can I decode a PDF file using this Base64 decode tool?
No, this tool is designed to decode Base64 strings back to plain text, not to decode PDF files directly. If your PDF file is encoded in Base64, you would need to extract the Base64 string from the PDF and then use this tool to decode it.
Is there a command or function to encode or decode Base64 in Python or JavaScript?
Yes, both Python and JavaScript have built-in functions or libraries that support Base64 encoding and decoding, such as Python's base64 module or JavaScript's btoa and atob functions, which this tool also uses for its conversions.
