Encode ordinary text or read a local file and produce its Base64 representation. Copy the output immediately or download it for later use.
Common Base64 encoding uses
Developers use Base64 for binary representations, test fixtures, and embedded resources. It is not encryption, so sensitive information still requires real access control and cryptography.
How to use this tool
- Enter text or switch to file mode.
- Run Base64 encoding in the browser.
- Copy or download the generated output.
Private, local processing
Your input is processed locally by the browser on this device. NexaForge does not upload the file or text to its server, which keeps private work under your control.
Frequently asked questions
Will NexaForge upload or store my input?
No. Processing happens locally in your browser, and NexaForge does not receive or store the source file or text.
Does Base64 protect confidential data?
No. Base64 is a reversible representation and provides no encryption or access protection.
