The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM, SVG, etc.ģ. If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). The image quality option only works on a few image formats such as JPG, WEBP or AVIF. You can use the original image size or select the "Change width and height" option and enter a custom image size. Set target image format, image quality and image size. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.Ģ.

I have not tried uploading such files to Dropbox (yet) but intend to, to see if removing any extraneous layers helps.1. I use PNGs with drop shadows and bezels all the time in many different applications, and I always remove any non-visible layers. Always advisable to take any invisible layers to the trash. Not ALL applications support transparent PNG files unless the file itself is devoid of any "invisible" (there, but layer turned off in Photoshop) layers that might become visible if the application cannot distinguish between a layer that is visible and a layer that is not. I'm guessing that while Dropbox doesn't "edit" the file, the layer gets flattened with the visible layer and the resulting file is combined. First, if there is a white layer in the backgroung where the layer is turned off in Photoshop, the white layer is still there but not visible. If the PNG files are being saved from Photoshop, there are several things going on. What applications are you using for that? As has been said Dropbox simply cannot edit files, so you may wish to look at how they are being edited and uploaded.
