Data Encoding for the Web
Different systems expect data in different formats. URLs need special characters escaped. HTML requires entities for certain characters. Binary files need text representation to embed in code. Our encoders handle these transformations — and can reverse them when needed.
Base64 Encoding
Base64 converts binary data into a text string using 64 safe characters. This enables binary data like images and files to be embedded in text-only contexts like HTML, CSS, JSON, and email. Data URIs use Base64 to embed files directly: data:image/png;base64,...
URL Percent-Encoding
URLs can only contain certain characters safely. Spaces, special characters, and non-ASCII characters must be percent-encoded — converted to %XX format. Choose encodeURI for complete URLs or encodeURIComponent for individual query parameter values.
HTML Entity Encoding
HTML uses certain characters for syntax: < and > for tags, & for entities. When these appear in content, they must be encoded as entities to display correctly and prevent XSS security vulnerabilities. Our encoder handles named entities (©) and numeric entities (©).
Two-Way Tools
All our encoders work in both directions. Encode data for transmission, then decode to read it. Paste encoded text to see what it contains.
