[Shotwell] Editing metadata to .jpeg files

[Gosset Inofensiu]

Hello, good morning from Catalonia, Spain. Please excuse my English.

I've been using Shotwell for a year more or less, and it has helped me a
lot organizing all my digital photos from 2003 to present, creating events
and adding tags, titles and all other metadata to the pictures directly
keeping in mind that in the future i want to backup and restore the
database and all the photos from one PC to another, or when reinstalling a
new OS.

Since jpeg is a lossy format, I was wondering if everytime I write metadata
to a photofile the file suffers a loss. If so, I am considering converting
all my photos (thousands) to .png format, which seems to be lossless. Am I
wrong?

I would appreciate a lot some advice. Thanks in advance.

Regards
