A This tool only handles rounded corners. It won't blur or pixelate content. For blurring sensitive data like names or credit card numbers, you'll need a separate editing app first. Once that's done, come back here to add rounded corners. The whole process takes about 30 seconds. Pro tip: use a screenshot tool with built-in blur, then finalize with this tool.

A Your original image likely has a solid white background, not true transparency. The tool rounds corners by making those areas transparent. If the image itself has a white background, the corners will show white where the background remains. You'll need an image with an alpha channel (transparency) to get clear rounded edges. Try opening a PNG with a transparent background instead. Most screenshots and JPEGs lack transparency.

A Once you save and close the file, those rounded corners are permanent. The tool doesn't keep a backup. If you need flexibility later, save two versions: one with rounded corners and the original. Some photo editors can reverse transparency, but that adds steps. Best practice is to process a copy, leaving your original untouched.

A It shouldn't crash, but you might notice some lag. The tool processes everything locally in your browser, so a 20MB image takes more work than a 2MB one. Give it a second or two after moving the slider for the preview to update. For the smoothest experience, crop giant photos down before uploading. No files ever leave your machine, so memory is your only bottleneck.

A Yes. Every pixel stays on your machine. The tool runs entirely in your browser using JavaScript. No image gets sent to our server or any third party. This means your private photos, client work, or sensitive screenshots never leave your device. Nifty for web developers who need to round corners on prototype assets without worrying about data leaks. You can even disconnect from WiFi after the page loads.
