B4X FEED Better photo compression

[practicalsoft]

I need to reduce the space occupied by the photo. Ideally, the photo should weigh less than 1.5Mb. For this I use the code:

I have already encountered the problem that if sometimes I reduce the “quality” parameter to less than 50, then large distortions already appear in the photo, so in the condition I used to reduce the quality until the photo weighs more than 1.5Mb and the quality is not equal to 50. But even now I sometimes encounter large photo defects during compression.
Is there a better photo compression algorithm?
