I was thinking of renaming every images extension to PNG but as my lap is crapped out and i am broke as hell i would have to do it on phone is there any good app on fdroid that can do it in a bulk ? Also does renaming the end from “jpg” to “png” actually change the format ? This pictures are very important to me as they have an imotionall connection to me.
On a less important note is this the same for mp3’s too as i save my favourite songs in the same way as a zip file is m4a better ?
Oh thanks i was really worried there for a sec . Also read the edit and see if that changes anything .
None of it matters.
JPEGs “lose quality” when people are editing them. If you take a JPEG and add text over it for a meme, the image gets worse. If someone opens your edited version and writes new text over that, the image gets worse. Etc. Plus websites that host images sometimes automatically compress them more, losing more.
All the other stuff you’re talking about doesn’t care about the format. Compression, encryption, etc, are all based on the assumption that the files have to be exactly the same. They use methods that don’t lose anything.
