Step 2: change dir to photos directory
cd /root/fff7860c7319fa20c8340eb813637fba-i
Step 3:
Linux:
mogrify -format jpg pagepng-*.png
Windows:
C:/ImageMagick/mogrify.exe -format jpg pagepng-*.png
Done!, now you have many jpg photos.
You can specify quality of JPEG output:
C:/ImageMagick/mogrify.exe -quality 60 -format jpg pagepng-*.png
Custom output path:
C:/ImageMagick/mogrify.exe -path /path/to/output -format jpg pagepng-*.png
If you don’t use step 2, you can use this command for step 3:
mogrify -path /root/fff7860c7319fa20c8340eb813637fba-i -format jpg /root/fff7860c7319fa20c8340eb813637fba-i/pagepng-*.png
