Is there a way to transfer/backup pictures and videos without losing quality?

I am trying to backup all of my android (LG G4) pictures and videos to my external hard drive.

I tried using the build in "import pictures and video" but when I browsed the files I noticed that the pictures on my phone had a bigger file size then the one imported. some of them were even half the size.

so I want to know if there are other methods for doing so or maybe I did something wrong in the importing process.

I also want to ask if there are other forms of backup for those files? maybe compressing them and when I will need them in the future I could decompress them for full quality?
 
Solution
Connect the phone to your PC with data cable and copy the pictures manually (copy >> paste) to the backup location. Copied files should then be identical to the originals - same file size etc.
