Check PowerPoint notes and metadata locally
Speaker notes and hidden slides can contain information outside the visible slideshow. The checker detects supported note text, hidden-slide and shape markers, properties, comment containers and relationships. Property cleanup preserves slide and notes parts byte-for-byte; it does not remove notes, comments or embedded media. Open the output and review all remaining findings.

Before you check.
Are speaker notes removed by metadata cleanup?
No. Notes and other presentation content are preserved. The report shows detected text or structures; it is not a full rendering or content audit.
Does a clean copy mean my file is safe?
No. We remove only supported metadata and list what remains. Visible content and other unsupported information may still reveal private details.
Which files can I check?
JPG, JPEG, PNG, static WebP and supported HEIC photos; PDFs; DOCX, XLSX and PPTX Office files; and supported MP4/MOV videos. The screenshot editor accepts JPG, PNG and static WebP. Batches allow up to 10 files and 100 MB total. See Supported formats for each tool’s limits.
