Metadata and SEO
When a PDF is on your website, Google often shows its Title as the search result heading. A PDF titled "Microsoft Word - final_v3.docx" looks careless; a clear title gets more clicks.
Many apps read the XMP copy of the metadata before the classic one. Both are updated together so every reader shows the same details.
Tip: Uploading PDFs to your website? Give each one a clear title and description first.
Your files stay on your device
Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
