Closed edmundlaugasson closed 1 month ago

Is your feature request related to a problem? Please describe. Images are quite large in file size. Then also exported PDF comes too large.

Describe the solution you'd like Please allow to change image compress ratio in case of PNG. Currently same quality setting from JPG applies also to PNG. Quality setting for PNG could be but compression ratio is important to reduce file size.

Describe alternatives you've considered Use lossy JPG format and reduce it's quality.

Additional context JPG loses quality on every saving. PNG does not but if poorly compressed, images and also exported PDF will come too large. Using Android 11. Newest app itself from Google play.
