🔧 Common Pitfalls & Troubleshooting Guide

⚠️

Unexpected Input Formatting Error

Probable Cause: Source text or uploaded file contains unsupported characters or exceeds file size thresholds.
Recommended Solution: Verify your input matches the accepted format guidelines and does not exceed the maximum file size limit.
⚠️

Browser Tab Sluggishness or Freezing

Probable Cause: Running multiple resource-intensive browser tabs or processing very large files on memory-constrained mobile devices.
Recommended Solution: Close unused browser tabs, refresh the workspace, and process files in smaller increments.
⚠️

Clipboard Copy Button Does Not Respond

Probable Cause: Certain mobile browsers restrict automated clipboard access if the page lacks active user tap gesture focus.
Recommended Solution: Tap the result text box directly, select all, and copy manually if browser clipboard permissions are restricted.
