Frequently asked questions
What encoding formats are supported?
URL encoding and decoding, HTML entity encoding and decoding, and Base64 text encoding are available.
What is URL encoding used for?
URL encoding converts special characters in URLs to percent-encoded form so they can be safely transmitted in HTTP requests. For example, a space becomes %20, and an ampersand becomes %26.
What are HTML entities?
HTML entities are codes that represent special characters in HTML. For example, the less-than sign becomes < and the greater-than sign becomes >, preventing the browser from interpreting them as HTML tags.
Is this the same as the developer Base64 tool?
Yes, the Base64 text encoding here is equivalent. This tool is in the Text Tools section for accessibility. Both encode and decode Base64 text strings.
Does it work offline?
Yes.
Why would I need to decode a URL-encoded string?
Debugging API requests, reading encoded query parameters, and analyzing redirect URLs often require decoding URL-encoded strings to see the original values.
Is URL Encode/Decode Free free to use?
URL Encode/Decode Free is completely free with no subscription, no trial period, and no credit card required. There are no usage limits, watermarks, or premium tiers. The tool is funded by the existence of the wider OnlineToolsPlus platform rather than by charging users for individual tools.
Does URL Encode/Decode Free work on mobile devices?
Yes. URL Encode/Decode Free works on any modern smartphone or tablet — iPhone, iPad, Android phones and tablets. Open it in Safari, Chrome, or Firefox on your device and it functions identically to the desktop version. The interface is responsive and adjusts to smaller screens automatically.
Do I need to install anything to use URL Encode/Decode Free?
No installation is required. URL Encode/Decode Free runs entirely in your web browser. Open the page and start using it immediately. There is no app to download, no browser extension to install, and no account to create. It works on Windows, macOS, Linux, iOS, and Android — any device with a modern browser.
Is my data private when using URL Encode/Decode Free?
Yes. All processing happens locally in your browser. No data you enter — text, files, or settings — is sent to any server or stored anywhere outside your device. OnlineToolsPlus has no server-side processing for this tool. Your data is as private as anything else on your device.
- Sensitive documents stay private. Contracts, financial statements, personal photos, and medical records never leave your device.
- No account required. There is nothing to sign up for, no password to manage, and no personal information collected.
- No usage limits or rate limits. Browser-based tools are not throttled by server capacity. You can use the tool as many times as needed.
- Works offline (after first load). Once the page is loaded, most functionality works without an active internet connection.
This matters for several reasons:
URL Encode/Decode Free on OnlineToolsPlus runs entirely in your browser. No file, text, or data you enter is ever sent to any server. Processing uses the JavaScript APIs built into your browser — the same environment used by banking and healthcare applications.
