This tool allows you to encode and decode multiple text items simultaneously. Each item can use a different encoding type and encode/decode mode. Use the "Add Item" button to process multiple strings at once.

Instructions:

1. For each item, select the encoding type and whether to encode or decode.
2. Enter your text in the input field.
3. The encoded or decoded result will appear automatically in the output field.
4. Click Add Item to add another item (it will use the default encoding and mode, which you can change).
5. Use the Copy icon to copy a specific result.
