Metadata Editor & Cleaner

See what information your files contain before sharing them. Metadata Editor & Cleaner lets you inspect supported metadata, edit individual fields and save a separate copy while keeping the original unchanged. TOOLS FOR YOUR FILES • Inspect descriptions, authors, dates, locations and technical properties when available • Edit supported values, add compatible missing fields or mark individual fields for removal • Use the private-data profile or remove all supported removable fields • Process one file or a batch of selected files • Check changes and content integrity before offering the copy for saving • Export a TXT report with metadata and SHA-256 file hashes • Use light or dark themes and an interface in ten languages SUPPORTED FORMATS Images: compatible JPEG, PNG and WebP files. PDF: edit supported title, author, subject, keywords, creator, producer and date properties. Known document-level XMP copies are synchronized; a compatible XMP packet can also be removed. This is not a raw XMP/XML editor. Audio: MP3 with compatible ID3v2.3/ID3v2.4 or ID3v1 tags, FLAC, and supported OGG Vorbis/Opus streams. Edit information such as title, artist, album, genre, track number and comments. Video and audio containers: supported MP4, MOV and M4A metadata. Office documents: compatible DOCX, XLSX, PPTX, ODT, ODS and ODP document properties. ODT/ODS/ODP are OpenDocument formats used by OpenOffice and LibreOffice. COMPATIBILITY AND LIMITS Available actions depend on the actual file structure. Technical properties may be read-only. HEIC images are not edited. PDF and Office files are limited to 128 MiB each. Additional metadata-size and structure limits apply. Signed or encrypted documents, legacy DOC/XLS/PPT files, fragmented media, ID3v2.2 and complex or chained OGG streams are excluded from editing. Information is shown read-only when it can be read safely; some files cannot be opened. Other metadata, artwork, comments, embedded files or revision history may remain. Cleaning is not a guarantee of complete anonymization. Supported edits preserve the image, document content and audio/video streams without media recoding. The app checks the prepared copy before saving; it does not turn an unsupported file into a compatible one. LOCAL PROCESSING, ALL TOOLS INCLUDED Your files are processed on your device.
