Convert PDF pages to images without uploading

The usual reason is a destination that will not take a PDF: a slide, a chat message, a ticket, a listing. The page being pasted is frequently an invoice, a certificate or a letter, and pasting it somewhere is already a disclosure decision. Making the image should not add a second one.

There is a genuine side effect worth understanding. Because rasterising discards the text layer entirely, only what is visible ends up in the picture. Text sitting invisibly under a filled rectangle does not survive into an image. That is a real improvement over sending the PDF, and it is the same property that makes the result unsearchable, unselectable and unreadable by a screen reader.

Choose the format for the page. PNG holds crisp edges on text and line art; JPG is smaller on pages that are mostly photographs and will soften small type. Large or dense pages consume your own machine's memory while they render, so a two hundred page document is better done in sections than all at once.

You can watch this one happen. Open the network panel, convert a page, and see that only the image download occurs and nothing goes out. Disconnecting the network first gives the same result, which is the point: the rendering is arithmetic on your own machine.
