When I export my pictures my from Lightroom they are blurry

Hi, I am in Lightroom and I've edited some clear sharp pictures, but when I went to export the pictures and upload to Pixieset the pictures are blurry. I don't know what to and I need to deliver this album. Please

Can you please let us know the exact version of LR you are using and more important, the export settings you use. A screen-capture of the settings would be helpful.

Also please tell us what software you are using to view the photos after export, and what magnification are you viewing them at (100%? something else?) after export.

If you say so.

Without including screen shots of what you are seeing we can't tell or have any suggestions.
