Upload the PSD mockup you downloaded from BoostMockups
Photopea will load the mockup with all its layers, just like Photoshop — it’s basically magic.
Step 2: Locate the Smart Object Layer
In the Layers panel (on the right side):
Look for a layer labeled double click or Smart Object
It usually has a small square white icon — double-click it 💡 This will open a new tab with the editable design space
Step 3: Add Your Design
Once the smart object opens in a new tab, drag and drop your phone case design (PNG) onto the canvas
Resize and center it as needed
When you’re happy with the placement, click File → Save (Smart Object) or press Ctrl+S (Cmd+S on Mac)
🎉 This will update the original mockup with your design automatically!
Step 4: Save Your Final Mockup
Go back to the original mockup tab — you’ll see your design beautifully placed on the phone case
Click File → Export As → PNG or JPG
Download your final product image, ready for Etsy, your website, or social media
Cha-ching! Your case just got Boosted.⚡️
