Details, guidance, and common questions
The working tool stays first. Open these sections only when you need more context.
Base64 conversion is common in technical handoffs
Base64 often appears in APIs, tokens, embedded data, and debugging tasks. Having a lightweight encoder and decoder nearby saves time when you only need a quick conversion.
This tool handles the work in your browser so you can test payloads, inspect strings, and move between readable text and encoded output without extra setup.
Helpful tips for a better result
- Use encode mode when you need a text-safe representation of a string.
- Use decode mode to inspect readable content before sharing or editing it.
- Switch to the image tools if the Base64 data represents an uploaded image.
Frequently asked questions
Does Base64 encryption protect my text?
No. Base64 is an encoding format, not encryption, so it should not be treated as a security feature.
Can this handle multi-line text?
Yes. You can paste longer text blocks and convert them directly in the browser.
Does the tool support Unicode text?
Yes. The encoder and decoder are built to handle regular Unicode text, not only plain ASCII.
