Printing Confusion

Ooops. I meant .png.

This Adobe article https://www.adobe.com …mparison/jpeg-vs-png.html summarizes:

"JPEGs are hugely popular with photographers and businesses that manage large image libraries. Their smaller file size allows multiple digital photos to be shared and downloaded simultaneously. By making efficient use of storage space, JPEGs can keep an image library relatively streamlined, with no long wait times for files to open ...

"In comparison, PNGs aren’t really built to store high-quality photos. They specialize in handling detailed, high-contrast web graphics. They’re often the default format for screenshot images since they can provide a highly accurate representation of your desktop and don’t compress pixels together. A huge color palette and lossless compression ensure they retain plenty of detail — making them a popular choice for illustrations and charts."

Is the resolution actually more important than the file size?

Yes.
Resolution is the number of pixels in an image. The pixels are the photo you see. Less pixels means less data/detail in the photo.

File size is just a measure of how much space a file takes up on disk. A file that has been heavily compressed will take up less space on disk than an uncompressed file but the data in the file (once it is uncompressed) can be exactly the same... meaning any photo would be the same.

Thanks Kirk.

In the end I'm probably OK to just use full size .jpeg's.

Appreciate the insight!

The printer should be able to tell you how to get the best quality print from their work flow. I would convert to the color space they suggest and use the highest quality jpeg (since they don't take TIF).
