工作原理
Files quietly carry hidden metadata: photos store GPS coordinates and your camera/phone model; PDFs and Office documents store author names, the software used, and edit history. Most "metadata remover" sites upload your files to do this — defeating the purpose. This one works entirely in your browser.
- 1You drop in filesMix photos (JPG/PNG), PDFs, and Office documents (DOCX/XLSX/PPTX). They're read into your browser's memory — never uploaded.
- 2Metadata segments are parsed outFor images, the EXIF/XMP/IPTC segments and comment chunks are removed directly from the file structure — the image data is left byte-for-byte intact, so there is zero quality loss.
- 3Documents are stripped cleanPDFs have their title, author, producer, and XMP metadata cleared via pdf-lib. Office files (which are ZIP archives) have their core, app, and custom property files wiped via JSZip.
- 4You download the clean filesGrab each file, or the whole batch as a ZIP. A summary shows exactly what was removed from each one.
This is privacy tooling, so it would be self-defeating to upload your files. Everything runs locally — ideal for journalists protecting sources, anyone sharing photos publicly without revealing their home location, or professionals sending documents without leaking internal author and company names.
