Percent Encoding
Ensures link validity by replacing unsafe characters (spaces, symbols) with OS-compliant percent codes.
100% Client-Side
Your URLs and parameters are processed entirely in your browser. Sensitive data never touches our servers.
Free URL Encoder & Decoder: Sanitize Links Online
Instantly convert special characters into URL-safe formats or decode percent-encoded strings back to human-readable text. RFC 3986 compliant.
The Science of Web Address Sanitization
URLs can only contain a specific subset of ASCII characters. When your link includes spaces, emojis, or international symbols, it becomes "unsafe" and can cause page load failures or broken redirects.
Why URL Encoding is Mandatory
- Browser Consistency: Different browsers handle raw special characters differently. Encoding ensures your link works universally.
- API Communication: Pass complex JSON data or multi-word search queries through URL parameters without corrupting the request.
- Marketing Accuracy: Correctly format UTM parameters to ensure your referral data is captured accurately by Google Analytics.
- Security Hardening: Encoding user-supplied data is a foundational step in preventing Cross-Site Scripting (XSS) attacks through malicious URLs.
Modern Web Standards
Our tool follows the RFC 3986 standard for percent-encoding, the global benchmark for URI characters. Whether you are building social share buttons, debugging server logs, or generating dynamic redirects, GraphiKly provides the precision required for modern web development.
Percent Encoding
Convert spaces, symbols, and non-ASCII characters into standard percent-encoded sequences.
Safe Parameter Decoding
Easily decipher cryptic URL parameters and API response strings back into plain English.
Browser-Native Privacy
No data is sent to external servers. All encoding/decoding is performed locally in your browser.
Instant Conversion
Real-time processing as you type. No page reloads or 'submit' buttons required.
Enterprise Grade Tools for Everyone
GraphiKly tools are engineered with a privacy-first approach. All processing happens directly in your browser using modern WebAssembly and WebGL technology. No data ever leaves your device.
