FAQ
What input should I use with URL/Base64 Encoder?
Use values that match the URL encoding, Base64 task, then adjust the visible options before running the tool.
Can I copy the URL/Base64 Encoder result?
Yes. Review the output first, then copy or download it when the result matches your expectation.
Can I use URL/Base64 Encoder on mobile?
Yes. The input, options, action, and result areas are designed to stack cleanly on small screens.
Will ads interrupt URL/Base64 Encoder?
No. Ad slots stay outside the input, output, and primary action areas so the tool remains usable and policy-safe.
Can URL and Base64 conversion run on the same page?
Yes. You can review URL encode, URL decode, Base64 encode, and Base64 decode output directly in the browser.
Are strings sent to a server for encoding?
No. Input strings are converted in the current browser and are not uploaded to server storage or logs.
When should I use URL encoding instead of Base64?
Use URL encoding for query strings and special URL characters, and Base64 when binary-like data or tokens need a text representation.
