Changing DPI breaks transparent background

[jackjohnbrown]

I have a png with a transparent background that I’ve imported into Designer on my iPad Pro. Original dpi was 150. I need to upload it to an online vendor that only accepts 300 dpi files. (I know.)

Changing the dpi in Designer only seems to work if I uncheck Embed Metadata in the Export screen — but when I do that and save as png, the resulting image has a white background. If I leave the setting checked, the background is transparent but the dpi remains listed as 150. 

Is it possible to change the dpi of the saved png to 300, but retain the transparency?

edit: I’ve discovered that I can make this work if I first create a 300 dpi document and then use Place Image to add my image. I can then turn off embed metadata and retain transparency. Still not sure why I can’t start with an existing png, though.

Hi @jackjohnbrown

I could not replicate this issue. Any chance you can attach the PNG or a screen recording with your workflow?

Thanks,

Gabe.

What the heck—just did a walk through while screen recording and it worked fine! I feel like I may have forgotten to turn off resampling during my first go-through, could that have been the issue? I’m attaching the screen recording anyway but maybe this isn’t an issue after all.

Really odd. Unless you can replicate it, it might have just been a one-off error. Let us know if you have any more issues.
