Convert URLs and Base64 strings instantly. No waiting, no delays, just instant results.
All conversions happen locally in your browser. Your data never leaves your device.
Convert both URL to Base64 and Base64 to URL with a single tool. Perfect for all encoding needs.
Our Base64 to URL converter is a free, fast, and reliable online tool designed for developers, data engineers, and anyone who needs URL-safe encoding. Convert URLs to Base64 for API requests, data transmission, or storage, and decode them back when needed.
Base64 URL encoding is a method to safely encode URLs and other data for transmission in text-based systems. It converts binary data to ASCII characters and replaces URL-unsafe characters (+, /, =) with URL-safe alternatives (-, _, no padding). This ensures data can be transmitted safely in URLs, JSON, and other text formats.
URL to Base64 conversion is commonly used in API development, data transmission, and when URLs need to be embedded in other data formats. It's essential for passing URLs as parameters in APIs, storing URLs in databases safely, or when URLs contain special characters that might cause issues in certain contexts.
Yes, absolutely! All Base64 encoding and decoding happens locally in your browser using JavaScript. No data is sent to our servers, ensuring complete privacy and security. Your URLs and encoded data never leave your device, making it safe for sensitive information.
You can encode any valid URL including HTTP, HTTPS, FTP, and other protocols. The converter handles URLs with parameters, special characters, query strings, and fragments. It properly encodes Unicode characters and international domain names (IDNs).
Regular Base64 uses +, /, and = characters which can cause issues in URLs. URL-safe Base64 replaces + with -, / with _, and removes padding (=) characters. This makes the encoded string safe to use in URLs, query parameters, and filenames without URL encoding.
Yes, our decoder works with Base64 strings from any tool that follows standard encoding practices. It can handle both padded and unpadded strings, and automatically converts URL-safe Base64 back to standard format during decoding.
While there's no strict limit imposed by our tool, practical limitations exist due to browser memory and URL length restrictions in various systems. Most modern browsers can handle URLs up to several thousand characters, but for optimal compatibility, keep encoded strings under 2000 characters.
