How to use
Three steps to soft rounded corners
No account, no queue, no cloud job. Drop files, dial the radius, download when Result looks right.
01
Add images
Drop JPG, PNG, WebP, or HEIC files onto the rounder. Nothing is uploaded — rounding runs in your browser.
02
Dial the radius
Drag the corner-radius slider (percent of the shorter side, default 12%). Live preview fills the stage like Image Crop — no separate zoom control.
03
Export and download
Default transparent PNG for soft UI cards and icons. Switch to JPG/WebP with a background fill when you need a solid canvas. Batch up to 20 with ZIP when available.
Round corners without uploading
Drop a card or icon above, dial the radius, export transparent PNG, and download when the preview looks right.

Frequently asked questions
Can I round image corners without uploading?
Yes. Fogkits clips a rounded rectangle and encodes the result in your browser. The file never leaves this device for this tool.
Is the round corners tool free?
Yes. Browser-local round corners is free — no account and no credits. Export PNG, JPG, or WebP when the Result preview looks right.
How does the radius work?
Radius is a percent of the shorter side of the image (0–50%, default 12%). That keeps the same soft look across a batch of different sizes. The live UI also shows the equivalent pixels for the selected image.
Does round corners keep transparent corners?
PNG (default) keeps real transparent pixels outside the rounded rect. JPG fills corners with white, black, or a custom color. WebP can stay transparent or use a fill.
Can I round multiple images at once?
Yes. Add up to 20 images, set radius/format/background once, Round all, then download selected or Download all as a ZIP when zipArchive is present in the Fogkits build.
What is the maximum image size?
About 25 MB on typical desktops, or 12 MB on devices that report 4 GB of memory or less. Soft timeout is 60 seconds per image.
Need a circle avatar instead of soft corners?
Use Fogkits Circle Crop for a true circular pfp. Use Image Crop for rectangles, or Round Corners to straighten first.
Does HEIC from iPhone work?
Yes. HEIC/HEIF is decoded in the browser with heic2any, then rounded like any other still image.
