Frequently Asked Questions

Can I convert images to Base64?

Yes. Drag and drop any image file (PNG, JPEG, GIF, SVG) into the input workspace in **Encode** mode. The tool will parse and render the complete Base64 Data URL string instantly.

What is standard UTF-8 Base64 support?

Standard JavaScript `btoa` and `atob` fail when processing multi-byte Unicode strings (such as emojis or accented characters). This tool handles byte conversions correctly using URL percent-encoding wrapping to safeguard characters.

Is Base64 secure?

No. Base64 is a data packaging format, not encryption. Base64 strings can be decoded by any standard terminal or utility instantly. Do not use this tool for credential storage.
