@lacerto I inisist that I don't talk about physical size, a pixel on a screen is a pixel, zoomed or not (the size its render is another question. If I have an image of 100px, I want it to measure 100px, whichever the number of millimeters it's displayed at the end. It works well with jpg and pdf export. @Hangman Thank you for the videos, but there is no reason that the size in pixel is not enforced. At the end, acrobat displays a certain size at 100%, there has to be a mean to decide in my design software what this size will be. Il Indesign, if you set your document to a certain size, it will be outputed this size. Same in Publisher with JPG and PNG. When I export to png with publisher, whatever the resolution in dpi is, the output file size in pixel is the same as the document setting. I simply want the same thing for pdf export, like it works on indesign, photoshop and illustrator (and Publisher for other file formats). You can see the pixel size in the pdf file property (on mac not PC) I think that there is a calculation at play with pdf export that should not be there. Thank you for the second video with the acrobat settings, I will use ths system default DPI (mine was set on custom 110 dpi, don't know why) but this mean that on a Mac for example, it will not be displayed at the same number of pixels as the default resolution is 147. Thank you for yourr time, I will look this forward and continue my testing of Publisher with my deck of slides 👍

I sent my reply to fast and completed it before your previous post, sorry. The reason I want to display it true size in 100% is that I need standardized 1920×1080 slides and an output size that I can control, so i'm sure how it will be displayed on a 1080 TV on fullscreen, without upscaling or downscaling without side effects like blur or aliasing effects. I did that all the time in Indesign withour issue. Really, the dpi document setting must not be taken in account in PDF export when it's a pixel document exported as screen pdf. With trial and error, I find that the correct dpi to have the right output on Windows seems to be (nearly) 110dpi, don't know why as 100% zoom in win 11 is 96dpi.

Yes I thought of that from the start and tried 96dpi but the output in pixels is still not correct with this dpi setting For the example, I can't give you the real one but the file it in my first post act exactly the same. My PDF would be presentation slides, displayed in browser or acrobat, ideally at true size.

Hello, thank you for your replies and your help. I know that for a physical size like paper size, the number of pixel, coupled to DPI, ate just an information of density. But I'm trying to make a digital document, with a certain number of pixels, displayed on screen, and the size is the pixel in this case. If my screen is 1920 pixel wide, I want my pdf to be displayed to this size at 100%, in pixels. I tried 72dpi as a base, but the output is more than 1920px. I wonder if it's not a Windows issue as my friends on mac seems to have the correct size outputted if they set the document attached on the first post at 72dpi.

Thank you for the reply but i'm still a little bit puzzled : How can I have Publisher document, at 1920×1080px, showed at this true size in zoom 100% in publisher, that export to a pdf which is exactly 1920×1080px when opened at 100% in acrobat? Thank you for your help!

Hello, I'm trying to make full HD PDF slides, standard 1920 × 1080 px. I create a new document, web (or A4, same thing), 300dpi, RGB, 1920×1080, so far so good. Then I do an PNG or JPG export, all good, the dimensions of the exported images are correct. Then I try a PDF export, with same resolution, 300dpi, same as the document : And when I open this pdf, it's really small, 460×260 approx. (wich seems to be (1920|1080)/300×72, orienting me on a dpi problem) So I tried to change the resolution of the document and export to 72dpi but then the pdf is huge (~2933×1633) and I can't find why. The issue are : If I define a document size in pixel, I want that the output have the same number in pixels, despite the dpi seting. Dpi are for the physical world, and must not be taken in account when setting a document size in pixels How can I export a pdf from Publisher with a precise and predictible size in pixels? How to reproduce : Create a document, any size, any dpi (e.g. 300) Export it in PDF, open it and set the zoom tu true size in acrobat and see that it's not the same size as your Publisher document. Other test : When I export a 100×100 @100dpi document and export it, the pdf export is ~110px, and when I open it in Publisher, the document size is 72pts (wich does not convert to 110px). Please help, I just want to export my slides 😭🤯 Find the tests documents attached. (Designer V2.4.0, Windows 11) Sans titre.pdf Sans titre.afpub
