About the Base64 & URL Encoder / Decoder

The Base64 & URL Encoder / Decoder converts text to and from Base64 and URL (percent) encoding in one place. Encode a string into Base64 for a data URI, an API token or an email header; decode a Base64 blob back to readable text; or percent-encode and decode query-string values that contain spaces and special characters. Full Unicode support means Khmer and emoji round-trip correctly.

This free tool by Hosting Cambodia runs completely in your browser, so any secrets or personal data you paste never leave your device. It's a daily-driver utility for web developers, integrators and anyone debugging APIs.

Frequently asked questions

Is Base64 encryption?

No. Base64 is an encoding, not encryption — it makes binary or special text safe to transmit as plain ASCII, but anyone can decode it. Never use it to protect passwords or secrets.

When should I use URL encoding instead?

Use URL (percent) encoding for values you put into a URL — query parameters, paths — so characters like spaces, &, ? and Khmer text don't break the link. Base64 is for embedding binary-like data.

Does it handle Khmer and emoji?

Yes. The tool encodes and decodes full UTF-8, so Khmer script, accented characters and emoji convert correctly in both directions.
