Base64 Encoder / Decoder
Convert plain text to Base64 encoding, or decode Base64 back to readable text. Supports standard and URL-safe Base64. Everything runs locally — no data leaves your browser.
Use this Base64 encoder and decoder to convert plain text to Base64 or turn Base64 back into readable text. It supports standard and URL-safe Base64 and runs entirely in your browser, so the text you enter is not uploaded to Votilo servers.
How to use the Base64 encoder and decoder
- Choose whether you want to encode plain text or decode an existing Base64 value.
- Paste or type the text you want to process into the input area.
- Run the conversion and review the result immediately in the output area.
- Copy the result when you are ready to use it in a document, URL, configuration file, or development workflow.
What Base64 is useful for
Base64 represents binary or text data with a limited set of printable characters. It is commonly used when data needs to travel through systems that are designed primarily for text, such as JSON payloads, data URLs, configuration values, email-related formats, and developer tools.
Base64 is an encoding format, not encryption. Anyone who has a Base64 value can usually decode it without a password, so it should not be used to hide passwords, secrets, API keys, or other sensitive information. URL-safe Base64 replaces characters that can be inconvenient in URLs and filenames while preserving the same basic encoding idea.
Privacy and limitations
Encoding and decoding are performed locally in your browser. Votilo does not need to upload the text to a server for this tool to work. Very large inputs may still be limited by your browser and device memory. A successful Base64 decode also does not prove that the decoded content is safe or trustworthy.
Frequently asked questions
Is Base64 encryption?
No. Base64 is a reversible encoding format. It does not provide confidentiality or password protection.
What is URL-safe Base64?
URL-safe Base64 uses characters that are easier to place in URLs or filenames, typically replacing the standard + and / characters.
Does Votilo upload my text?
No. This tool performs the conversion in your browser and does not require the entered text to be sent to a Votilo server.
Can Base64 contain images or files?
Yes. Binary files can be represented as Base64 text, although this particular text tool is intended mainly for text-based encoding and decoding workflows.
Why does Base64 output look longer than the input?
Base64 trades compact binary representation for a text-safe character set, so encoded data is normally larger than the original bytes.
