Hello Cydoni!
Thank you for your post and feedback!
I looked into it and it seems to export images at 75% quality by default.
I'm planning to add an additional parameter slider, where you can set the quality yourself, and also set the default to 95%, and also add an additional option where you can keep file size low as an option.
The supported import formats are PNG, GIF, BMP, JPG, JPEG, WEBP, TGA, TIFF, WMF, ICO, APNG, MP4.
I thought that might be a little bit long for an info box, but I will see if it fits.
I understand the utility of resizing the window, but it is more complicated than I would like it to be, to set it up correctly with correct proportions.
I will look into it however when I have the time to see if there's something I can do!
Thanks again for the feedback, and I will write you here if I have made some progress on it!
