Everything about Flatten Transparency

Flatten Transparency is built for the moment when a PNG or other transparent image needs a solid background for upload, export, or print. It keeps that conversion quick and repeatable across a whole set.

What is Flatten Transparency?

Flatten Transparency is a browser-based utility for images with alpha channels. It replaces transparent areas with a solid background when the destination needs a flat file.

How it works

Open one image or a full batch, choose a background color, export the flattened files, and download the results right away.

Why teams use it

Some platforms, print flows, and support workflows do not handle transparency well. This tool makes that cleanup quick and predictable.
