Encode and Decode Base64 Instantly at Convert-Text.net
Welcome to Convert-Text.net's Base64 Encoder & Decoder, the fastest way to convert any text to Base64 or turn Base64 back into readable text. Paste a string into the box above and click Encode to get its Base64 representation, or paste Base64 content and click Decode to recover the original value.
No sign-ups, no uploads, and no limits. Every transformation runs locally inside your browser, so your data never leaves your device.
Common Uses for Base64
- Embed Images in HTML & CSS: Inline small images as Base64 data URIs so they load with the page and need no separate network request.
- Transfer Binary in JSON and APIs: Ship bytes such as file uploads or encryption keys inside text-only JSON payloads.
- Store Binary in Databases: Keep binary values in text columns without relying on vendor-specific BLOB handling.
- Decode Received Tokens: Quickly inspect JWT segments, email attachment data, or encoded configuration values you received from a client or vendor.
How to Encode or Decode Base64 in 3 Steps
- Paste Your Text: Type or paste the text (or Base64) you want to transform into the input box above.
- Choose Your Action: Click Encode to produce Base64 output, or Decode to recover the original text from Base64 input.
- Copy the Result: Click the Copy button in the result section and paste the output wherever you need it.
100% Client-Side Privacy & Security
Your text never leaves your browser. Convert-Text.net encodes and decodes everything locally with the browser's built-in TextEncoder, TextDecoder, and Base64 primitives. Nothing you paste is uploaded, logged, or stored, so this tool is completely safe for tokens, configuration values, and confidential documents.
Frequently Asked Questions
What is Base64 encoding?
Base64 is a way of representing binary data (or any string) using only the 64 ASCII characters A–Z, a–z, 0–9, +, and /, plus = for padding. It exists so that binary data can survive transport through text-only channels such as email, JSON, or HTML.
Is Base64 encryption or a security feature?
No. Base64 is a reversible encoding, not encryption. Anyone who sees the output can decode it instantly without a key, so never use it to protect passwords, tokens, or other secrets.
Does the decoder handle Base64 with line breaks or spaces?
Yes. Whitespace is automatically ignored when decoding, so multi-line Base64 pasted from emails or command-line tools works without any cleanup.
Is my text stored on your servers?
No. Convert-Text.net does not send your text to any server. All encoding and decoding runs inside your browser, and your input is gone the moment you close or refresh the tab.
Is the Base64 tool free to use?
Yes. Convert-Text.net is 100% free with no registration, no usage caps, and no artificial size limits because the work happens on your machine.
