WATERMARK SLAYER
Remove hidden characters from text
Invisible Unicode characters can arrive through copy-paste, editors, layout systems, or intentional language shaping. Watermark Slayer removes supported low-risk marks and keeps risky cases reviewable.
Try the hidden character remover
Paste the exact text into the homepage editor. Watermark Slayer preserves the raw input while showing a readable representation, then returns the cleaned text and the change record.
Why not delete every invisible character
Zero-width joiners, non-joiners, bidirectional controls, variation selectors, and word joiners can be meaningful in languages, emoji, typography, or interchange. Blanket deletion can corrupt text.
- Supported cleanup remains explicit
- Risky controls stay report-only
- Review changes shows what was altered
Hidden does not mean malicious
The presence of a format control is an observation, not an authorship verdict. Legitimate software and writing systems use many of the same code points.
