About PDF Thumbnail Generator
PDF Thumbnail Generator renders the pages of a PDF as small PNG or JPG images at a width you choose. Each thumbnail shows its page number, pixel size and file size, can be downloaded on its own, and all successful thumbnails can be downloaded together as a ZIP in page order.
Thumbnails are useful for document libraries, previews on a website, slide overviews and quick visual checks. Making them locally keeps private documents on your device.
