Why Add Rounded Corners?
Rounded corners give images a polished, modern look. They soften the harsh edges of rectangular photos and make them feel more integrated into designs — which is why every major design system (iOS, Material Design, Windows Fluent) uses rounded corners extensively.
Common use cases:
- App screenshots — rounded corners match iOS and Android device aesthetics for marketing materials.
- Social media graphics — cards, thumbnails, and story images look more professional with rounded edges.
- Blog post images — rounded corners add visual polish to hero images and inline photos.
- Presentation slides — images with rounded corners look cleaner than sharp rectangles.
- Profile images — create a modern avatar style that’s softer than a circle crop but more interesting than a square.
- Product mockups — match the rounded aesthetic of modern device frames and UI elements.
How to Add Rounded Corners Online (Step by Step)
The PPImage Rounded Corners tool adds customizable rounded corners to any image instantly.
Step 1 — Open the tool
Go to ppimage.com/rounded-corners. No download or account required.
Step 2 — Upload your image
Drag and drop your image or click to upload. JPG, PNG, and WebP formats are supported.
Step 3 — Set the corner radius
Use the radius slider to control how rounded the corners are. A small radius (10–20px) creates a subtle rounding, while a large radius creates a more dramatic "squircle" or pill shape.
Step 4 — Choose the background
Select what appears behind the rounded corners:
- Transparent — exports as PNG with alpha channel (best for layering in designs).
- White — clean white corners for documents and presentations.
- Custom color — match your brand or background color.
Step 5 — Download
Click Download to save your rounded image. Transparent backgrounds are saved as PNG; solid backgrounds can be saved as JPG or PNG.

Pro Tips
- Use transparent backgrounds — export as PNG with transparency so the rounded image blends seamlessly into any background color.
- Match your design system — if you’re designing for iOS, use a 22% corner radius (corner radius ÷ shorter side). For Material Design, 16dp is standard.
- Batch process — upload multiple images at once to apply the same corner radius to an entire set.
- Combine with borders — add rounded corners first, then use the Border tool to add a colored border for extra polish.
- Consider the aspect ratio — very wide or very tall images may need a proportionally larger radius to make the rounding visible.
