Exported jpg different than what GIMP shows

[Sygon_Paul]

Hello! I spent the last few hours adding an alpha channel and removing the bordering white from an image. When I exported in GIMP as a jpg, the end file still has the white. I do not know enough to tell if this is a jpg issue, a GIMP issue, or a user (me) issue.

If this is an issue with jpg files, how can I work around this, as I need jpg? I can try other image formats, but would prefer jpg because LibreOffice Writer doesn't like png format.

I am using GIMP 2.10.38 on Windows 11.

Attached is the exported jpg file. I can't seem to be able to attach a second image, so I will attempt to reply with that.

Are there any transparent areas in your image? If so GIMP will save these as the background colour when you export to jpg.

The Jpeg format doesn't support transparency, plain and simple. This is a format restriction, not a Gimp one.  When you export to Jpeg, transparent parts are replaced/filled by the background color.

No problem using PNGs with LO writer (24.2.7) though... What version are you using?

Same as other posts: Export image formats that support transparency:  png / tif /psd

LO version 7.6

Thank you for the replies. About two hours after I asked, I discovered that jpg doesn't support transparency. I also learned I was doing something wrong in LibreOffice, and I can use png files. It wasn't wasted time, as I discovered a few tools in GIMP to remove the white box frame behind the image. Unfortunately, those tools washed out some white in the main part, so I removed the white background by hand.

There may be a better idea, but what I have now is working as intended, even if it took me three and a half hours.
