GIMP decreases quality of image after every saving

I used GIMP to draw and after couple of weeks I noticed that image isn’t as sharp as it was before. It seems GIMP can’t save a file without quality loss: the more times you save file, the less and less quality you get. Is it possible to change that, may be some settings? I’m not talking about exporting, but exactly about saving.

Answer

If you are talking about editing and saving a JPEG repeatedly, then what you have descirbed is normal behaviour.

JPEG is a lossy format. So, every time you edit and save a jpeg, it will degrade. The more you do that, the worse it will get.

This has nothing to do with GIMP. It’s because of the JPEG format itself, and how it uses compression. This will happen no matter what image editor you use, including Adobe Photoshop.

The solution is to save in a lossless format, such as GIMP’s native XCF format, or PNG, or TIFF. You should use GIMP’s native format if you want to preserve layers and text layers for further editing.
