"Get the content out of this PDF" can mean three genuinely different things, and picking the wrong one wastes time. Here's the difference between a PDF's text layer, its embedded images, and rendering whole pages as pictures.
Extracting the Text Layer
A PDF built from a word processor, website, or similar digital source contains an actual, selectable text layer — the same underlying text data you could highlight and copy in a PDF reader. Extracting this text pulls that data directly, cleanly, with no image processing involved. This only works, though, if that text layer actually exists — a scanned document has no such layer at all, since it's fundamentally a picture, not digital text.
Extracting Embedded Images
Separately from any text, a PDF can contain embedded image files — photos, graphics, logos — placed onto its pages. Extracting embedded images pulls out those original image files exactly as they were inserted, independent of the surrounding text or layout. A size filter is useful here, since PDFs are often full of tiny decorative images (bullet icons, dividers) that aren't worth extracting alongside genuine photos.
Converting Pages to Images
This is different from both of the above: rather than pulling out existing text or images, this renders an entire page — text, layout, and any images together — as one single flattened picture, like a screenshot of that page. It's the right approach when you need a visual representation of the whole page rather than its individual pieces, such as a thumbnail preview or an image to paste somewhere that doesn't accept PDFs.
Which One Do You Actually Need?
Want to reuse the actual written words? Extract the text layer. Want the original photos that were placed in the document? Extract embedded images. Want a picture of what the page looks like, exactly as laid out? Convert the page to an image. Confusing these three is the most common reason people end up with the wrong output entirely.

FAQ
Why does extracting text from some PDFs give perfect results and others give nothing? It depends on how the PDF was created. A PDF generated from a word processor or a website has a real, selectable text layer that extracts cleanly. A PDF made by scanning a paper document is really just a picture of text with no underlying text layer at all — extracting text from that kind of PDF returns nothing, because there's no text data to pull, only pixels.
What's the difference between extracting a PDF's embedded images and converting its pages to images? Extracting embedded images pulls out the actual photo or graphic files that were placed into the PDF, exactly as originally embedded. Converting pages to images (like PNG) instead renders each full page — including text, layout, and any images together — as one flattened picture, which is different data entirely and useful for a different purpose, like previewing a page as a thumbnail.
Why would extracting a PDF's embedded images skip some small images automatically? Many PDFs contain small decorative elements — bullet icons, logos, dividers, background textures — embedded as images even though they aren't meaningful photos. A minimum size filter lets extraction skip these small decorative assets and return only the images actually worth pulling out, rather than cluttering results with icon-sized clutter.
What resolution should I use when converting a PDF page to an image? It depends on the intended use. A lower resolution (1x) is fine for a quick on-screen thumbnail or preview, keeping the file small. A higher resolution (2x-4x) is worth the larger file size when the image will be zoomed into, printed, or needs to preserve fine text and detail clearly.
