FAQ
What is the difference between Full URL and Component mode?
Full URL mode preserves URL structure characters like /, ?, #, &, =, while Component mode encodes all non-alphanumeric characters.
How to batch process multiple URLs?
Click the batch button to expand the batch input area, enter one URL per line, then click encode or decode to process all lines.
How does auto-detect work?
The tool checks if the input contains %XX encoded characters. If more than 30% of non-ASCII characters are encoded, it treats the input as already encoded.
