I need to embed a jpg image into a pdf, but the output result appears with blurry image, I use these settings for importing
and these for exporting
and this is the result.

Your image is 450x747 and you use 300dpi, so you have pixels enough to fill 1,5inch x 2,49inch which is obviously not the case with your PDF. Screen dpi is usually around 72, so you can try importing the images with 72dpi. If you have a hi-res version, then you can set higher dpi.

2Changing the dpi isn't going to change the number of pixels available. If the only option is raster, then to get larger image you need… a larger image.– TetsujinJul 3, 2021 at 16:23

@Komental Even with importing/exporting using 72dpi I get the same problem. That image is issued from a government website with QR/Barcode to be scanned at police checkpoints, so I can't get another one with higher resolution. Jul 3, 2021 at 20:04

@Tetsujin The image looks fine with image viewer (at the left), but when I embed it inside a pdf using Inkscape it becomes blurry in the exported pdf (at the right). Jul 3, 2021 at 20:09

1@NarutoBijuMode - Tetsujin and Komental are correct here. Changing the dpi in the PDF settings will not give you sharper images, or a higher resolution image. When I try this, a raster image in Inkscape exported as PDF looks exactly the same quality in the PDF. If you want as a sharper image you'll need a higher resolution image. Jul 3, 2021 at 21:21

1@NarutoBijuMode The real reason the image is blurry is because there is some resizing going on. Set all dpi fields to 72 and it should be fine for screens. Your jpeg looks fine on the screen and it should look identical inside your pdf.– KomentalJul 3, 2021 at 21:48
