Why Round Image Corners?
Rounded corners feel modern, soften harsh edges, and fit card-style layouts and social feeds.
Benefits
- Modern look: Matches current UI and app design.
- Softer edges: Less sharp than a plain square crop.
- Consistency: Same radius across a set of images.
- Social-ready: Works well for avatars, cards, and thumbnails.
- Polish: Quick finishing touch before publish.
How Corner Rounding Works
A rounded-rectangle mask clips your image; pixels outside the curve use your background or transparency.
Processing steps
- Load Image data is read in the browser.
- Radius Corner radius is applied uniformly on all four corners.
- Mask Content inside the rounded shape is kept.
- Background Transparent or solid fill outside the image area.
- Export Encode to PNG, JPEG, or WEBP.
Corner radius guide
Pick radius based on image size and how rounded you want the look.
Radius values
- Subtle (about 5–10px) Light softening; still mostly square.
- Moderate (about 10–20px) Clearly rounded—common for web cards and social.
- Strong (about 20–40px) Bold rounding on larger images.
- Very strong (40px+) Approaches pill-like shapes on small canvases.

Frequently asked questions
What is corner radius?
Distance from the corner where the curve starts—higher values mean rounder corners.
Can I round only some corners?
This tool rounds all four corners the same. For per-corner control, edit after export or use other design tools.
What background should I use?
PNG with transparency for flexible placement; solid color when you know the page background.
Does rounding hurt quality?
It’s a geometric clip; quality inside the rounded area stays the same as your source.
Several images at once?
Yes—apply the same radius and background settings across uploads.
What radius for thumbnails?
Small images often use about 5–10px; larger images can use 10–20px or more for visible rounding.
All formats?
Yes; PNG is best when you need transparency. JPG has no transparency; WEBP can.
