Step 2: Configure the conversion/rescaling job
Make sure the “Do convert to format” checkbox is checked and select JPEG as the format. Check the “Do reduce image size” checkbox and select “Thumbnail” in the “Profile” list. You can uncheck the checkbox “Preserve EXIF/IPTC/XMP metadata” as we will not need metadata for these thumbnails. We did set the quality to 70% in order to compress the thumbnails a little bit more at low cost on the quality. The “Size preview” tells us that the whole set of images will be 664.1 kb large when the originals are 259.8 Mb.

So that “_small” is appended to the file names of the originals. The preview shows you how the final filename will look like: “P1000875_small.jpg”, “P1000876_small.jpg”, …
