Does this work with any PDF?

Any standard, unencrypted PDF up to 80 MB. The preview is made from the first page, so text and vector graphics are captured too, not only embedded images.

Can I choose which page the thumbnail comes from?

The preview always comes from the first page — the most useful choice for covers and title pages.

Is my PDF uploaded to a server?

The PDF is processed locally (or in a short-lived environment) and is not stored. Download the PNG immediately.

What about password-protected PDFs?

Encrypted PDFs are not supported — extraction fails cleanly with a diagnostic.

Extract a thumbnail from a PDF online

Many workflows need a small picture of a PDF: a cover preview for a catalog, a gallery tile, or a quick visual check. This page extracts a PNG thumbnail from the first page of your PDF, without installing a PDF reader.

How to extract a PDF thumbnail

Upload a PDF up to 80 MB.
Press Convert file.
Download the PNG preview from the result page.

What you get

A single PNG image rendered from the first page of your PDF — a small, shareable preview of the document exactly as a reader would display it.

When this helps

Adding cover previews to a document library, catalog, or portfolio
Generating shareable preview images for chat, tickets, or documentation
Checking what a PDF looks like without opening a viewer

The preview comes from the first page only. It does not extract embedded images, text, or attachments — use the related PDF attachment and PDF text extraction recipes for those.
