If a proof has more than one version, you will be able to compare versions.

## To compare proof versions

### Step 1

Open the proof and click the compare icon at the bottom of the screen. This icon will appear if the proof has more than one version.

### Step 2

The proof versions will display side-by-side. If the dimensions match exactly, smart compare is available. Comments can be added in compare mode too if the proof is in a status that allows commenting.

**Tip:** You can also compare two different proofs.
