Frequently Asked Questions
What encoding formats are supported?
Our tool supports URL encoding/decoding (percent encoding), Base64 encoding/decoding, and HTML entity encoding/decoding for comprehensive text transformation needs.
Why should I encode URLs?
URL encoding ensures that special characters are safely transmitted over the internet. It converts characters like spaces, symbols, and non-ASCII characters to a format that URLs can handle.
Is my data secure when encoding?
Yes, absolutely. All encoding and decoding operations happen entirely in your browser. Your data never leaves your device, ensuring complete privacy and security.
When should I use Base64 encoding?
Base64 is commonly used for encoding binary data in text formats, embedding images in HTML/CSS, or transmitting data in systems that only support text characters.
What are HTML entities?
HTML entities are special codes used to display reserved characters in HTML. For example, < displays < and & displays &. This prevents HTML parsing issues.
