This tool rounds the corners of an image by applying a rounded-rectangle mask and exporting the result, usually as a PNG. Use it when a website, CMS, app mockup, product grid, or profile image needs softened edges or transparent corner areas.
What Is Round Image Corners?
A round image corners tool changes a rectangular photo, logo, screenshot, or product image into a rounded rectangle by masking the corners. JPG is a flat raster image format and does not support transparency, while PNG is a raster format that can keep transparent pixels through an alpha channel. People often upload a JPG or PNG, set a corner radius, and export a PNG so the cut-out corner areas stay transparent. This is useful for UI cards, profile images, web thumbnails, app assets, and design files that need consistent rounded edges.
How to Round Image Corners
Upload your image
Choose a JPG, PNG, WebP, screenshot, logo, or product image from your device.
Set the corner radius
Use a smaller radius for subtle card styling or a larger radius for avatars, tiles, and pill-shaped images.
Preview the edges
Check the rounded corners against the image content, especially near text, icons, borders, and thin lines.
Export as PNG
Download the rounded image as a PNG when you need transparent corners, or use a filled background if transparency is not needed.
When to Use Round Image Corners
- Upload forms that require a square or rectangular image but display better with rounded edges.
- CMS images for blog cards, author bios, resource libraries, landing pages, and website galleries.
- Marketplace and ecommerce thumbnails that need a consistent rounded-card look across products.
- Profile photos, team headshots, community avatars, and directory images.
- UI and app assets such as cards, tiles, modals, onboarding screens, and dashboard previews.
- Design handoff files where developers need a PNG with transparent rounded corners.
- Screenshots for tutorials, documentation, pitch decks, and product pages.
- Logos or badges that need to sit cleanly on colored or patterned backgrounds.
Round Image Corners Tool vs Alternatives
| Tool | Best For | Corner Control | Output Options | Notes |
|---|---|---|---|---|
| Pict AI | Fast browser-based corner rounding | Radius-based rounded rectangle | PNG export for transparent corners | Focused image utility with optional mobile editing workflow |
| Photopea | Detailed image editing in a Photoshop-like workspace | Manual shape masks, selections, and layer effects | PNG, JPG, PSD, SVG, and other formats | Useful when rounding corners is part of broader layer editing |
| Canva | Templates, social graphics, presentations, and layouts | Rounded frames and image crop controls | PNG, JPG, PDF, and design exports | Useful when rounded images are placed inside a larger design |
All three tools can help create rounded image corners. The best fit depends on whether you need a quick PNG export, detailed layer editing, or a template-based design workflow.
Round Image Corners Limitations
- PNG transparency only works if the export format supports alpha transparency; JPG exports will flatten the corners onto a solid background.
- Very low-resolution images may show jagged or blurry curved edges after rounding.
- A large radius can crop important corner content such as text, logos, product labels, or UI controls.
- Rounding the corners usually does not change the canvas width and height; it masks the corners inside the same dimensions.
- Transparent corners may appear as black, white, or checkerboard in apps that do not display transparency correctly.
- Some platforms recompress uploaded PNG files and may remove transparency or convert the image to JPG.
- Batch processing may not be available, so large image sets may require separate automation or desktop tools.
- Rounded corners are visual pixels in the exported image, not editable CSS border-radius unless recreated in code.

Frequently Asked Questions
Yes. You can upload a JPG and export the rounded result as a PNG if you need transparent corners.
PNG supports transparency, so the removed corner areas can stay transparent. JPG does not support transparent pixels.
Usually no. The canvas width and height normally stay the same while the corner pixels are masked or made transparent.
Use a square image and set the radius to half of the image width or height. Rectangular images with a high radius become pill-shaped instead of circular.
Use a small radius for subtle web cards, a medium radius for product thumbnails, and a large radius for avatars or soft UI tiles.
Yes, if the file is exported as PNG and the destination app preserves transparency. The rounded image will show the page, slide, or design background behind the corners.
Rough edges usually come from low image resolution, heavy compression, or scaling after export. Use a higher-resolution source image when possible.
Yes, rounded PNG images are commonly used in CMS galleries, product cards, author profiles, and landing pages. Check whether the platform preserves PNG transparency after upload.
