one of your A4 size files

I still do not know if you understood my problem: I do not get A4 size PDF files, this is exactly my problem. I get files like the attached one, when I convert a JPG file just with reducing color depth to sw.

And now I would need a step to make an A4 size PDF file from ...

Ok, but are you sure this changes the PDF paper size? On my system, it does not.

That changes the DPI value without changing the number of pixels.

No, it doesn't. It also has a bug, since it produces very big files, too - with the wrong paper size.
You could use any random image based PDF file to proof your recommendations. They fail due to bugs in XnConvert.

Yes, I tried that - and there must be at least one bug: settings like 210 x 297 mm lead to 21 x 29 mm pdf files, with a very low resolution, not readable.

Settings like 2100 x 2970 mm lead to the correct paper size of 210 x 297 mm, but to very large files. (50 KB --> 1 MB)

The tool should not ...

So for many purposes the actual output image DPI should not matter.

Maybe, but I have one of the rare purposes where it does matter. But apart from this, the way XnConvert reduces color depth and making a small fax compressed pdf file from it, is outstanding and I would like to use it regularly ...

if you are only printing the output images

Unfortunately not. I want to save the pdf files. All I need is an action like "Fit to page"...

What I do not understand:
The settings for PS/PDF say: Page size A4. But XnConvert seems to ignore that.

Hello!

Sometimes I get very large colour image based PDF files and I would like to reduce image resolution without changing papersize.

The action "Resize" in mode "MPixels" makes optically wonderful results, for example with 3 megapixels limitation for the image.

My problem is: this action also ...

Today I tried multipage with XnConvert 1.92 and: it works perfectly with Ghostscript 9.50!

Thank you!

XnConvert 1.90 is relatively old now
It is from December 2020. And XnConvert 1.82 is even older, but works fine with GS 9.50.

Yes, all is on 64 bit on my system. I do not use XnView, but only XnConvert standalone (https://www.xnview.com/de/xnconvert/)

Perhaps best thing is to wait for a new ...

More specific:

I use Windows 10 64 bit and Ghostscript 9.50 64 bit, and XnConvert 64 bit of course.
XnConvert 1.82 makes multipages PDFs with Ghostscript 9.50 64 bit, but not with the newest (Ghostcript 9.54)!
XnConvert 1.90 fails with both Ghostscript versions, converts the first page only.

HTH

Hi all,

seems XnConvert lost a main feature in 1.90: when loading a multipage pdf file, and choosing Output: "Convert all pages from multipage file", yet only the first page of the pdf is processed. :shock:

XnConvert 1.82 did process all pages, one after another, and made a new multipage pdf file ...
