Generating a thumbnail image of a PDF's first page gives you a visual preview for display in file browsers, web interfaces, document management systems, or email previews. PDFStream renders the first page at your chosen resolution and exports it as a JPG or PNG image. The thumbnail faithfully represents the page layout, fonts, and graphics. Use cases: creating a cover image for a document management system, generating a preview image for a file-sharing link, producing a thumbnail for display on a website, or creating a preview for a document selection UI.
