How to round image corners
- Add your images. Drop them onto the box above or tap to choose. JPG, PNG, WebP, AVIF, BMP and GIF files work, and you can add several at once.
- Pick a shape. Keep Rounded corners, or choose Circle for a round crop.
- Set the corner radius. Choose % or px and move the Corner radius slider. The preview shows the transparent corners on a checkerboard.
- Add a border and choose the format. Optionally switch on Add a border, then pick PNG (transparent) or JPG with a Corner colour under Save as.
- Press Round corners and download your images one by one or as a ZIP.

- Batch processing with a ZIP download and before and after file sizes.
Why use Fileora to round corners
Rounded corners make pictures look friendlier and more modern. They are everywhere in app screenshots, product cards, presentation slides and email signatures, and circle crops are the standard for profile photos and team pages. Most image editors hide this behind masks and layers.
Fileora does it in a couple of taps, with the result drawn right in your browser. Nothing is uploaded, there's no sign-up, no watermark and no limit on how many images you round. It works just as well on a phone as on a computer.
Crop your picture first with crop image if you want to control exactly what stays in the frame, especially before a circle crop. To turn a rounded logo into website icons, continue with the favicon generator, and use the image resizer to bring photos down to the size your page needs.
Choosing the right radius
A small radius of 2% to 5% gives a subtle softening that suits photos in articles and product galleries. Around 10% is the friendly, app-like look used for thumbnails and cards. 25% and above turns wide images into pill shapes with fully round ends at 50%.
Use % when you process a batch of photos of different sizes and want them all to match. Use px when you're following a design that specifies a radius, but remember the pixels are measured on the original image: a 40 px radius looks much smaller on a 4000 px photo than on a 400 px one, so check the preview.
PNG or JPG?
Choose PNG (transparent) for anything that will be placed on a coloured background, such as a website, slide or design, because only the picture itself shows and the corners disappear. The files can be larger than the original photo, as PNG is lossless.
Choose JPG when you know the background colour in advance, for example white for a document, and want a small file. Set the Corner colour to match the background, and the rounded corners will blend in seamlessly. The JPG quality slider starts at 90%.
Rounded images are new files, so camera details and location data from the originals are not copied across. Animated GIFs become a single still frame.
