PDF to JPG at the quality you pick

Dots per inch, not a mystery slider

A PDF page is measured in points rather than pixels, so it has no resolution of its own until something draws it. That makes the only question worth asking how finely to draw it: 96 dots per inch matches a screen, 150 is comfortable for most uses, and 300 is what printers expect. Docqify renders each page at the size you choose using your own graphics engine, so you get the picture you asked for instead of whatever a slider labelled quality decided.

• Pick the pages you want from the grid. Everything is selected to begin with, because converting a PDF to images usually means all of it.
• JPG has no transparency, so anything see-through is placed on white. If you need the transparency kept, use PNG instead.
• One page downloads as an image; several arrive together as a ZIP, because browsers block a run of downloads one after another.
• Very large pages at 300 dpi can exceed what a browser will allocate. Those are rendered slightly smaller rather than failing, and the result says so.
