Why are my PNG backgrounds not transparent when I upload them to Dropbox?
I had several files (mostly logos) that had a transparent background and they all have white solid backgrounds now. I have no clue what happened but it is causing me serious issues.
Dropbox is not editing your files... it is generating a copy of the file that does not include transparency and displaying that as a "preview" of your file to improve load times on their website.
Dropbox creates the image shown in the center which includes a white background. This means that dragging and dropping this image, or right-clicking and selecting "save image as..." will result in you downloading the Dropbox preview version. HOWEVER, if you use the "Download" button on the top right of the page, you will download the un-edited version of your file.
The problem is that while this change may have shaved a fraction of a second off page load time, it seems to have screwed up a lot of people's workflows as a result. I think Dropbox needs to consider changing it back or at least find ways to ensure these common workflows result in the desired outcome.
What on earth could have caused that? It's every one of my png files that is in my dropbox account. Some that were not stored on my computer. It's as if they were changed to jpg. I am able to open other png files with transparent backgrounds that are not in my dropbox account and they work just fine. Dropbox is the only common denominator.
