Frequently Asked Questions

Corner Rounder gives you the ability to set different radius values for each corner individually, while the basic Rounded Corners tool applies the same radius to all corners.

For iOS-style app icons, use a square image and set the radius to about 22% of the image width. For Android, use a slightly smaller radius around 15%.

Yes! Switch to "Individual" mode to set different radii for each corner. You can even set some corners to 0 while rounding others.

Why Use Snipinsta's Corner Rounder?

Round each corner by its own amount: the top-left, top-right, bottom-left and bottom-right radii are set separately, or switch to one radius for all four.

Four Independent Radii

Corner Mode switches between one shared radius and individual values per corner, so a tab shape, a speech-bubble card or a single rounded edge is a few sliders away.

Choose the Background

The area cut away by the rounding is filled with the background colour you pick.

Preview Before Download

Adjust the radii and check the result on the page before saving the file.

Processed on Our Servers, Then Deleted

The rounding runs on Snipinsta's servers; the upload and the result are removed within 24 hours.

Popular Use Cases

Chat and Speech Bubbles - Leave one corner square to point at the speaker, round the other three.
Image Grids - Round the outer corners of the images at the edge of a gallery while the inner ones stay square.
Device Mock-ups - Match a screen's corner radius on each side when a mock-up frame is asymmetric.
