What does this encoder decoder do?
This browser-based tool converts plain text and text-based file contents using common encoding formats. You can encode or decode content with Base64, URL encoding, or HTML entities without uploading files to a server.
Common use cases
Use it to prepare API payloads, decode Base64 text, clean or inspect encoded data, encode URLs safely, or convert HTML entities for debugging and testing.
It is especially useful for developers, QA teams, analysts, and anyone working with logs, exports, encoded strings, or web data.
Private browser-based processing
All encoding and decoding happens locally in your browser. Your file content stays on your device, which makes this tool fast and suitable for private text workflows.
