Batch Conversion Creates Larger File

[HarleyN]

Seems like this is either a bug or a programming issue. When using the batch conversion to convert a .jpg to either .afphoto or .png the converted file size is exceptional larger. A 3MB file will jump up to 50-100MB. Seems like the converted file should be roughly the same size as the original?

Does that also happen if you simply Open the file and then Save as a .afphoto or Export as a .,png file?

I opened a 2.1MB .jpg and saved it as a .afphoto which rendered to a 10MB file size. I then took the same original .jpg image and batch converted it to a .afphoto and it rendered at 38MB file size.  Also, no edits where made during this process.

I opened a 5.8MB JPEG and saved it as an .afphoto file which became 14.8MB. I then batched the orginal JPEG three times and got 5.9, 5.8 and 5.9 however the .afphoto that was created from the batch was 24.5MB all three times.

Our .afphoto files can 'bloat' so it's not too much out of the ordinary except that the batch consistently bloated more than a Save As.

I get a little bloating but this seems outright obese. A 4 to5 times increase in an unedited file seems a bit extreme. What threw me off was that generally my Indesign files where much larger then affinity publisher files. So I assumed Affinity was running a more efficient file format across the board. I love what Affinity is doing, just seemed like a hiccup.
