I have a pdf file that I want to resize after importing. However, ImageResize doesn't seem to take into account the high-resolution of the initial image, and resizing makes it very pixelated. I can rescale the original import by hand for better effect, but how can I get this result automatically?

G0 = Import["Structure.pdf"][[1]];
Style[Grid[{{G0, ImageResize[G0, Scaled[2]], G0}}],ImageSizeMultipliers -> {1, 1}]

Original import, image resize, and manually resized original image

    $\begingroup$ I guess, you should add the option "PageImages" into Import command. This will give you the full-scale images instead of the thumbnails $\endgroup$

In general, you should use the "EmbeddedImages" element when importing raster images from a PDF file:

Import["http://exampledata.wolfram.com/article.pdf", "EmbeddedImages"]

From the Documentation:


But your file "Structure.pdf" doesn't contain raster images - it is a pure vertor figure. Hence if you wish to convert it to raster, you can use the "PageImages" element with either ImageResolution or "RasterSize" option for controlling the resolution of the final raster image:

Import["Structure.pdf", {"PageImages", 1}, ImageResolution -> 300]


Import["Structure.pdf", {"PageImages", 1}, "RasterSize" -> 500]


Alternatively, you can import it as a vector figure, and then use Rasterize to convert it to a raster image:

vectFig = Import["Structure.pdf", If[$VersionNumber >= 12.2, {"PDF", "PageGraphics"}, {"PDF", "Pages"}]][[1]]
Rasterize[vectFig, ImageSize -> 500]
