Hidden Character Cleaner

Hidden Character Cleaner is a browser-based utility for finding and removing invisible Unicode characters such as zero-width spaces, joiners, BOMs, soft hyphens, and bidirectional control marks. These characters are hard to spot visually, yet they often cause frustrating issues in copy and paste workflows, search indexing, input validation, code snippets, URLs, IDs, spreadsheet imports, and AI-generated text.

A string can look correct on screen while still containing hidden code points that break equality checks or create confusing formatting behavior. This tool analyzes the input instantly, removes known hidden characters, and reports which code points were found so you can understand the source of the problem. It is useful when cleaning imported content, debugging suspicious text mismatches, sanitizing CMS fields, or checking data before you send it into another system.

Everything stays in the browser, so sensitive text never leaves your device. Your data is always private and secure, making this tool ideal for handling confidential documents, customer information, and any text that must remain local.
