• Using the wrong tool for the job. Make sure URL Encoder/Decoder is the right choice for your specific task by reading the description and features.
• Ignoring file format compatibility. Ensure the output format is supported by your intended application or platform before processing.
• Over-compressing files when quality matters. Balance file size reduction with acceptable quality loss by testing different settings.
• Uploading sensitive or confidential files to online tools that send data to servers. URL Encoder/Decoder processes everything locally, but not all online tools do.

• Use consistent indentation (2 spaces or 4 spaces) across your project for readability.
• When minifying code for production, keep a beautified source copy for debugging purposes.
• Generate UUIDs offline for database records to avoid latency and dependency on external services.
• Always validate your JSON before deployment — a single syntax error can break an entire API integration.
