Fix a PNG that looks white after export
Published
When a PNG looks white after download, open the file over a coloured surface. If the colour shows through the gaps, the PNG is transparent and the first viewer supplied the white backdrop.
Try these steps in the editor
Import the downloaded image into a coloured design. If a white rectangle stays visible, return to the editor. Choose PNG and Transparent under File background, then export again.
Check the downloaded result
Compare a received copy with your original download. Messaging apps can re-encode pictures. Attach the PNG as a document when transparency matters and reopen the received file. A screenshot of the preview keeps the displayed checkerboard as pixels.
