How to convert 4 band GeoTIFF to PNG or JPEG using gdal_translate [duplicate]

Question

I have an orthomosaic GeoTIFF and it has 4 bands. I want to convert it to a PNG/JPEG image to show it on Cesium. I've tried gdal_translate like this : gdal_translate -a_nodata 0 -of PNG 1.tif 1.png -scale -colorinterp_1 red -colorinterp_2 green -colorinterp_3 blue and it's not working. I'm completely new to QGIS. Can you please guide me what options I should use to get data? I already have 2D generated picture using photoshop and I think it's not losing any data. I don't want to keep projection or elevation data. I just want a normal image.

Point: it's not possible for JPG because I'm getting this error : libjpeg: Maximum supported image dimension is 65500 pixels

This is gdalinfo result :
