Extract Images or Render Pages? Choosing the Right Pull
Pulling a picture out of a PDF sounds like one job until the result is a blank logo or a folder of fragments. The mode decides whether you get the source image or a picture of the page.
Why this comes up
Scanned pages are one large image, while a designed brochure can contain dozens of small ones, and a chart may be vector art with no embedded image at all. The same tool needs a different mode for each.
Check before you run it
- Use single-image extraction when the picture was embedded. The tool writes the images it finds at their original pixel dimensions, named p
_ . A lone image downloads as one PNG; several arrive as a ZIP. - Render the page when the artwork is vector or the layout matters. A chart, a map or a logo drawn as vectors is not an embedded image. Converting the whole page at 150 DPI suits screens; 300 DPI suits print.
- Expect repeated placements to produce repeated files. An image reused across pages is written once per placement, with a running number. Sort the folder by name and compare before assuming the PDF contains duplicates.
When to reach for it
- A photograph needs to be reused outside the document. Extract the embedded image rather than screenshotting the page, so the file keeps the resolution the designer placed.
- A page of vector artwork must become a picture. Render the whole page at 300 DPI when there is no single embedded image to pull.
One question we get
What quality do extracted images come back in?
The original embedded pixels — no re-compression, often far better than a screenshot. Everything arrives as a zip, or convert whole pages to JPG instead.

Every tool works on a copy, so the original file is never touched. Uploads are stored under an unguessable id and deleted automatically two hours after you last open them; nothing is listed, shared or indexed. More on the security page.
