Guys, please take away this simple doubt that torments me kkk.
When I export a JPG image without any editing (the way I imported it was exported),
for some reason the exported image doesn't stay with the same size (in bytes) of the imported image.
In fact, the exported image gets even bigger.
The original image is 3.92 MB, 96 DPIAfter exporting with Corel it is 12.3 MB, 96 DPI
As I said before, I did not do any editing on the image to justify such an increase in the size (in Bytes) of the exported file.
Why can't the imported image (the original) and the exported image (which was not edited) have the same quality and size in bytes?
I also made a video demonstration:

When you import a JPG image (any image) into CorelDRAW, it is no longer a JPG but instead just an uncompressed image with a given number of pixels.The JPG compression that was in the original file is no longer present but the deterioration caused by this compression is now part of the image.When you export as a JPG, DRAW compresses the image again based on your export settings, and the new JPG may be bigger or smaller than the original and it may also look more or less "destroyed" compared to the original image.JPG uses a lossy compression algorithm that will impair the image each time it is opened and saved.
BINGO!
Ronny Axelsson said:JPG uses a lossy compression algorithm that will impair the image each time it is opened and saved.
This is a great thing to point out.
JPG can be useful as a "final destination", but it can be a poor choice of format for editing, saving, editing, saving, etc.
If you post on Facebook it's the worse format to use. They take your already damaged image and greatly increase that damage by resaving it as a higher compressed JPG and embedding a URB RGB profile not only making you image worse but slowing FB. I use PNG with far better results.
Facebook often automatically converts any uploaded PNG images into a severely compressed JPEG image.
