It shouldn't but that depends on the initial and final resolution, I mean if you have resized the PNG, especially if it was a small pic that you've enlarged, then such blur will occur because the PNG format is not designed to be interpolated for resizing.
Can you upload a sample file (if more than 128kB, use a 3rd party file sharing web site)?

The image where actually downsized in draw but when I zoom on it is perfect. When I export it it is quite blurry.
I tested again by importing/exporting without modification but the blur remain.
I just found a similar discussion elsewhere:
https://superuser.com/questions/686793/ ... ffice-draw
From what they say it seems to be a known problem with the export of libreoffice.
However I found a workaround for now. If I select an image in draw and copy it directly in writer, the "drawing" will be copied correctly. There is then issue for resizing (keep ration doesn't work) but I hope that when exported as pdf everything will be fine. I hope XD

I will stick with the workaround for now. Nonetheless thanks for the help and have a nice week!

Can you upload nonetheless a sample so that we can see?
I made some tests and what I see is that if the initial PNG is set to its original size in AOO, then the export is exactly identical to the initial PNG. However, if the size in Draw is smaller, then indeed the quality of the exported PNG is lower than the original.
