- Does this turn whole pages into images or pull out the photos inside?
- It can do either, and they are different jobs. Rendering makes a picture of the entire page, layout and all, which is what you want for a thumbnail, a preview or posting a page online. Extracting instead saves only the photos embedded in the PDF, at their original quality, when you want the pictures themselves rather than the page around them.
- What resolution should I choose?
- Match the dpi to the destination. Screen resolution is plenty for a web page, an email or an on-screen preview, while a higher dpi is worth it when the image will be printed or zoomed into, since it captures far more detail at the cost of a larger file. Rendering above the detail actually present in the page will not add sharpness, only size.
- JPG, PNG or TIFF, which format fits my page?
- Pick JPG for pages that are mostly photographs, where its compression keeps files small with little visible loss. Choose PNG for pages full of text, line art, screenshots or diagrams, where crisp edges and optional transparency matter. TIFF suits archival or print pipelines that specifically ask for it. When in doubt, PNG is the safer choice for anything with sharp text.
- How are the images named and delivered, and what happens to my file?
- Each image is named from the original document plus its page number, so ordering stays obvious, and you can download them individually or as a single zip. Your PDF is processed for the session and then deleted automatically, no account is required, and the original stays untouched on your device.
