Libroffice draw batch conversion of jpg to png

English
#1

I put all jpg-files in C:\001
I placed a file batch3.bat in C:\001 Only one line in that file:
for %%x in (.jpg) do “C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:/000” “%%x”

The execution lines show as follows:
PS C:\001> .\batch3.bat

C:\001>for %x in (.jpg) do “C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:\000” “%x”

C:\001>“C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:\000” “001.jpg”

C:\001>“C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:\000” “002.jpg”

C:\001>“C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:\000” “003.jpg”

C:\001>“C:\Program Files\LibreOffice\program\soffice” --headless --convert-to png --outdir “C:\000” “004.jpg”

In directory C:\000 I found my four png-files

Question What CLI-tools do the same job?

#2

And what is the question?

Personally, I’d convert using dedicated CLI utilities which are specifically designed for this task. They can also more easily be scripted with more conversion options.

#3

What better CLI tools do the same job?

#4

Under Linux, convert, ffmpeg and imagemagick among others. There may be equivalent utilities under Windows.

I’m using Imagemagick also under Windows. For interactive jobs I prefer IrfanViews “batch mode”, but you can also access this from batch files

Thanks for the advice. I installed Imagemagick, it will take a while to get the hang of the commands but it seems to have a lot of possibilities.

#7

I just installed Irfanview and after installing the plugins for Win 64 the batch conversion of any set of images from any location to any other format is child’s play.
I don’t mind using CLP-apps but this Irfanview batch conversion is my first choice now!
Thanks again for the advice.
