PDF to JPG
Render every page as an image at screen or print resolution and download them together as a zip.
300 DPI is what a printer wants and it is roughly seventeen times the pixels of 72, so a long document at 300 will take a moment and produce large files.

Why DPI rather than a percentage
Most tools offer a scale multiplier, which tells you nothing about whether the result will print acceptably. The question people are actually answering is either "will this look right on a screen" or "will this survive a printer" and both have standard answers in dots per inch.
The conversion is simple enough to do in your head: a PDF point is a 72nd of an inch, so rendering at 150 DPI is a scale of 150 over 72, a little over double. The tool does that for you and reports the pixel dimensions of each page.
What you lose
Everything that makes a PDF a document rather than a picture. Selectable text, working links, the ability to search it, any form fields and the vector sharpness that lets a page be zoomed indefinitely. An image of a page looks identical at the size it was rendered and falls apart above it.
That is often exactly what is wanted: an image goes into a slide, a chat message or a web page without anyone needing a PDF reader. Just keep the PDF, because this conversion only runs one way.
The reverse
Going the other direction, photos or scans into a single document, is theimage to PDF tool. That one does produce a real PDF, with pages sized as you choose, though the pages are images so the text in them isn’t searchable either.
Common questions
What resolution should I pick?
72 DPI for anything going on a screen, 150 for a good balance and 300 if it is going to a printer. The numbers aren’t arbitrary: a PDF point is a 72nd of an inch, so 72 DPI renders the page at exactly its intended size in pixels and 300 DPI is the resolution most print workflows assume.
Why is 300 DPI so slow and so large?
Because it is roughly seventeen times the pixels of 72 DPI. An A4 page at 72 is about 595 by 842 pixels; at 300 it is about 2480 by 3508. Both the rendering and the resulting files scale with that, so a long document at print resolution is a real amount of work for the machine.
JPG or PNG?
JPG for pages that are mostly photographs or scans, PNG for pages that are mostly text, line art or flat colour. JPG compression puts a faint grey halo around sharp edges, which is exactly what text is made of, so a text page as JPG at low quality looks subtly dirty.
Does the text stay selectable?
No and it can’t. An image is pixels, so converting a PDF page to an image discards the text layer entirely. If you need the text, extract it from the PDF rather than rendering it or run the images through OCR afterwards, which is a lossy round trip.
Is my document uploaded to be rendered?
No. The rendering engine runs in this tab, which is the same engine your browser uses to display PDFs natively. Nothing leaves the device, which matters for the contracts, statements and records that make up most of what people convert.

All of them work the same way: the file is read in your browser and never uploaded.
