Examples

1. Uniform Profile Avatars

Social Media Manager
Background
The team needs to update 20 employee profile photos to have a consistent, modern rounded look for the company website.
Problem
Manually editing each photo in professional software is time-consuming.
How to Use
Upload the headshot, select 'All Corners' mode, set the radius to 50px, and export as PNG to maintain transparency.
Outcome
All profile photos now feature perfectly uniform rounded corners, ready for immediate upload to the website.

2. Custom UI Card Design

Web Designer
Background
A designer needs a specific card graphic where only the top two corners are rounded to fit a website header layout.
Problem
Standard image editors often round all four corners by default.

Upload the banner image, select 'Top Corners Only' in the Corner Mode, and set the radius to 20px.
Outcome
The banner image is perfectly cropped with rounded top corners, fitting the header design seamlessly.

Can I round only specific corners?

Yes, use the 'Corner Mode' setting to select top, bottom, left, right, diagonal, or custom individual corner configurations.
