I need to make a transparent image with a png 24 format, NOT 32. Photoshop saves any image with transparency only as 32png. How do i get around this?

  • So someone or something tries to tell you that you need this. Can you elaborate on who or what this is, and did you question whether they can possibly be right? Commented May 6, 2017 at 10:12
  • I need it to make a snapchat geofilter. There it says that the image must be 24png and transparent at the same time. @MichaelSchumacher

    PNG32 is just PNG24+transparency... which you need. Have you actually had any trouble uploading the image? ...because I'm pretty sure what you have should be fine.

24 bit PNGs do not have the alpha channel. There are only the normal R,G and B channels - total three bytes per pixel.

One can sacrifice one color for transparency. This can be useful if the storage space is limited and it's OK to have opaque colored pixels, fully transparent pixels and no partially transparent pixels. For watching the images he needs a special program that knows which RGB combination should be rendered as transparent

It can be also possible that someone says "I want PNG24 images" to be sure he gets 16 million possible colors, not only 256 colors as with PNG8. In addition he wants the full alpha transparency (=partial transparency possible in every pixel and color), so actually he wants PNG32.
