Match the cleaning tool to the problem
Clean Tools covers three different kinds of file cleanup. Use Filename Sanitizer when the names themselves need changing, such as unsafe characters, reserved names, or length-limit issues. Use Metadata Remover when you need to inspect and remove recognized embedded metadata from a supported image, PDF, audio, or OOXML Office file. Use ZIP Junk File Cleaner when the problem is operating-system clutter stored as entries inside a ZIP archive.
These scopes are separate: renaming a file does not remove its embedded metadata, and removing metadata does not generally rewrite the filename. ZIP Junk File Cleaner checks archive entry paths for known clutter; it does not scan or clean the contents of the files inside the archive.
Know what each tool accepts and returns
Filename Sanitizer accepts one or more files of any type. It previews each original-to-proposed name mapping, then downloads a renamed copy for one file or a ZIP containing renamed files and CSV and JSON mapping manifests for multiple files.
Metadata Remover accepts one file at a time. Its supported inputs include JPEG, PNG, WebP, PDF, MP3, WAV, FLAC, and OOXML Office documents. It lists recognized metadata before removal and provides a cleaned copy plus a removal report.
ZIP Junk File Cleaner accepts one ZIP archive at a time. It displays candidate paths, sizes, matching rules, and warnings so you can review keep or exclude choices, then downloads a rebuilt ZIP and a removal manifest.
Review the important limits before cleaning
- Filename Sanitizer applies configurable naming rules and warns that filesystem compatibility is not guaranteed for every destination.
- Metadata Remover handles only metadata structures it recognizes. MP4/MOV/M4A, HEIC/HEIF, Ogg, many video containers, TIFF-based raw formats, and legacy binary Office files are unsupported. PDF and Office outputs may be regenerated, so their bytes or size can differ even when visible content is preserved.
- ZIP Junk File Cleaner reports invalid archives and unparseable central directories as unsupported. Encrypted entries are locked to Exclude; unsafe paths, duplicate paths, and copy failures are surfaced for review or in the result and manifest.
A practical way to choose and review the result
- Choose the tool based on the scope of the change: names, embedded metadata, or ZIP entry clutter.
- Load the supported input and review what the tool identifies before applying a change. Filename Sanitizer previews proposed names, Metadata Remover lists recognized fields, and ZIP Junk File Cleaner shows candidate entries and warnings.
- Adjust the visible options or keep/exclude choices, then use the tool's action to create the result.
- Download the cleaned copy and its mapping or removal report where provided. Each child interface states that processing occurs in browser memory and that the original input is not overwritten.
