Features of the Image Border & Rounded Corners Tool
A free tool that lets you batch apply rounded corners and borders to multiple images at once.
When embedding screenshots in blog posts, you can instantly round the corners slightly or add a subtle border to prevent them from blending into the background.
No need for image editing software like Photoshop -- create polished images right in your browser.
What You Can Do
- Rounded Corners: Neatly rounds all four corners of your images (supports transparent PNG). The corner radius is specified as a percentage of the image's shorter side, ensuring a consistent look across images of different sizes.
- Add Borders: Adds a border with your chosen color and width around the image. Choose any color from the color picker, and fine-tune the width to your preference.
- Batch Processing: Process dozens of images at once via drag and drop. Download all results as a ZIP file for efficient bulk editing.
- Real-Time Preview: See the result instantly in the preview area whenever you change settings. You can adjust as many times as you like.
Recommended Use Cases
- Blog & Article Creation: Adding rounded corners with a thin gray border makes screenshots look much better. If screenshots blend into a white blog background, simply adding a border solves the problem.
- Presentations & Slides: When inserting images into PowerPoint or Google Slides, applying uniform rounded corners and borders to all images gives the entire presentation a cohesive look.
- E-commerce & Product Images: Add a subtle border to product images to distinguish them from the background, or use rounded corners for a softer impression.
- Social Media Icons & Thumbnails: You can even crop square images into circles by setting the radius high enough. Great for creating profile pictures.
Simple 3-Step Process
- Drag and drop or click to select the images you want to edit (multiple selection supported).
- Adjust the corner radius, border width, border color, and save format to your preference. Fine-tune while watching the preview.
- Click "Process & Save Images" to start. Once complete, download individually or as a ZIP.
Supported Formats
Supported input formats are JPEG, PNG, and WebP.
You can save as either "PNG (preserves transparency)" or "JPEG (white background)."
Choose PNG to keep transparent areas created by rounded corners, or JPEG to reduce file size.

Frequently Asked Questions (FAQ)
Q. Does the image quality degrade?
A. Images are processed at their original resolution. Saving as PNG is lossless. Saving as JPEG may result in slight quality changes due to re-encoding.
Q. Can I use this on mobile?
A. Yes. It works directly in iPhone and Android browsers. You can select images from your camera roll or file manager.
Q. How many images can I process at once?
A. There is no specific limit, but it depends on your device's memory. Processing a few dozen images at once should work without issues.
Q. Can I apply only rounded corners or only a border?
A. Yes. Set the corner radius to 0% for border-only, or the border width to 0% for rounded corners only.
