Bulk file cleaner
Drop multiple files at once — we scan them all and show you exactly what invisible characters and formatting junk each one contains. Then clean them all and download a zip.
🔒 100% private — files never leave your device
📦 bulk — TXT · MD · HTML · CSV · JSON · RTF · DOCX
🔍 scan first — clean only when you say so
Drop files to scan them
We'll report what's inside each file — invisible characters and formatting junk — before touching anything.
How it works
- Scan. Drop one or many files and we report exactly what pollution each carries — invisible characters by type, plus formatting junk.
- Decide. Review the findings. Nothing is changed yet.
- Clean & download. Click "Clean all files" — we strip the pollution from every file and hand you a zip of the cleaned results.
What it cleans
- Invisible characters — zero-width spaces, joiners, BOMs, soft hyphens, variation selectors.
- Formatting junk (TXT/MD/HTML) — stray code fences, excess blank lines, over-deep headings, trailing spaces.
- CSV/JSON structure is preserved — only invisible characters are stripped.
Honest limits
- PDF direct cleaning isn't supported yet — use the plain text extractor.
- DOCX output preserves content; open the result in Word to confirm.
