FAQ
No. All parsing happens inside your browser. The only network request is downloading the file you are inspecting from the site it is already on. Files you drop into the viewer never leave your computer.
These platforms strip EXIF data when an image is uploaded, so there is nothing left to read. That is expected, not a bug. Original files (email attachments, cloud drives, personal websites, PDFs and Office documents) usually keep their metadata.
The panel only appears when the tab shows a file directly (an image, PDF, video or audio URL), not on normal web pages. For a normal page, use the popup's page scan. Also check that "Auto panel" is on in the popup.
Some sites block downloads that do not come from their own pages. MetaLens retries once in the background with the source page as Referer. If that also fails, save the file and drop it into the viewer.
PDFs that need a password to open and password-protected Office files are encrypted; MetaLens only shows their encryption details. PDFs that open without a password but restrict printing or copying are decrypted and fully analyzed.
JPEG, PNG, WebP, GIF, SVG, PDF, DOCX/XLSX/PPTX, ODT/ODS/ODP, MP4/MOV/M4A, HEIC/AVIF, MP3, FLAC and WAV. Encrypted PDFs, MKV, OGG, AVI and legacy DOC/XLS/PPT files are analyzed but not cleaned. The result always lists anything that was left behind.
The document info and XMP metadata are removed. Images placed inside the PDF may still carry their own EXIF, and older revisions of an edited PDF may remain in the file; both are pointed out in the result. For maximum safety, print the PDF to a new PDF before sharing.
Up to 512 MB. For large PDFs, videos and photos only the parts that hold metadata are downloaded when the server supports HTTP Range requests.
