When a pbix file is published, its size increases.
Hi Zarina_Hajiyeva ,
Thanks for reaching out to the Microsoft fabric community forum.
To fix your PBIX file size issue, try deleting the current 1962 MB semantic model from the Power BI Service instead of overwriting it.
Before republishing, open your PBIX file in Power BI Desktop and clear any cached data by going to File - Options and Settings - Options - Data Load and selecting Clear Cache. Saving the PBIX file with a new name also helps prevent metadata issues.
Publish the PBIX as a new dataset from Power BI Desktop there should be no prompt to replace an existing one. After publishing, check the dataset size in System storage to confirm it matches your model’s actual size. This method ensures accurate file size and eliminates unnecessary metadata from previous versions.

Super UserHi Zarina_Hajiyeva It might be due to metadata overhead, compression differences, and potential historical artifacts from incomplete updates. Publishing with a new name avoids old artifacts, showing the correct size. Optimize the data model by reducing unused columns and clearing the dataset cache in the Service.
