hi,

I have a .tif file which comes from Adobe Photoshop 26.3 (Macintosh) with the following dimensions:

Width - 40 mm

Height - 17 mm

XResolution - 525.15 ppi

YResolution - 525.15 ppi

When I convert this file to pdf format using Acrobat Pro 2024 (Create PDF from File) the result is the wrong dimensions: 40 x 25.4 mm, instead of 40 x 17 mm.

Why is this happening?

I opened the .tif file in Photoshop and Illustrator (Windows 11) and the dimensions displayed is correct: 40 x 17 mm.
Thankyou!

Hi @Urraco37,

I tested with the TIFF image you attached and found that after converting it to PDF, exporting via Save As (right-click menu) or Convert to Image (with "Export All Images" checked) retains the original image dimensions.

If I'm not mistaken, you might be comparing the image dimensions to the page size (bottom left corner values). Since images adjust to fit the page, this could lead to inaccurate results. Let me know if you observe otherwise.

Hi @Utkarsh35493727za1t
When you converted my TIFF file to PDF file, why weren't the original TIFF dimensions size preserved?

Hi @Urraco37,

I converted the TIFF image you attached into a PDF and verified its embedded dimensions using Output Preview. The original TIFF dimensions were preserved. (Attaching a screenshot for reference.)

You can check this yourself by following these steps in Acrobat:

Open the PDF.
Click on "All Tools" to open the tools pane on the left.
Scroll down and click "View More" > Select "Use Print Production"
(Alternatively, press Ctrl + F and search for "Output Preview").
In the Output Preview dialog box, select "Object Inspector" from the dropdown.
Click on the image within the PDF to view its properties.

Let me know if you have any questions!

Hi @Urraco37 ,

Could you please share how you are verifying image dimensions in a PDF after converting it?

Thanks!

if you look in the bottom left corner and you don't see the page size, you have to go to Edit - Preferences - Page Display and check "Always show document page size"

In Acrobat the minimum is 1 inch.

The best practice is to save as a PDF directly in Photoshop.

the best practice for me is to convert PDF files from the Windows context menu "Combine files in Acrobat", but I understand that I can't convert files smaller than 1 inch using this method, as Bernd Alheit correctly pointed out.

Hi @Urraco37,

Can you please ensure you checked the "Preserve embedded profiles" option while creating PDF from tiff. Also, can you please share the file with us on which this issue is happening.
