Base64 Encoder & Decoder
Encode text to Base64 or decode Base64 online for tokens, headers, data URLs and development snippets.
What this tool does
Use URL encoding when spaces, symbols or non-English characters need to travel safely inside query strings.
How to use it well
Start with a small sample, check the output, then paste the full text when the result looks right. For important production data, review the output before saving or sharing it.
Common uses
- Encode query parameters
- Decode tracking URLs
- Inspect copied links
URL Encoder / Decoder workflow
Use this url encoder when you need a fast browser-based check before moving data into code, documentation, a report or another web tool. Start with a small sample, confirm the result, then process the full pasted text so mistakes are easier to catch.
Why it helps
The goal is to keep the task focused: paste input, run the conversion or check, then review a clear output without installing software. This is useful for developers, content teams, SEO work, support notes and quick QA checks.
