Frequently asked questions
Common questions about making image corners transparent.
What does "transparent corners" mean?
It means the corners of your image become see-through (transparent) with a rounded radius — like how profile pictures and app icons often have rounded edges. The interior of the image is unchanged. Only the corner areas outside the rounded boundary become transparent.
Why does the preview show a checkerboard pattern?
The checkerboard (grey and white squares) is a standard way to visualize transparency in image editors. Where you see the checkerboard, the exported PNG is transparent. When you place it on a website or in a design, those areas will show whatever background is behind the image.
What file format does the tool output?
PNG. It is the most widely supported format that preserves alpha-channel transparency. JPG does not support transparency, so the tool always exports PNG.
Do my images get uploaded to a server?
No. All processing happens locally in your browser using the Canvas API. Your image never leaves your device. There is no server upload step at all, and we cannot see your files.
Which image formats can I use as input?
The tool accepts any image format your browser can read: JPG, PNG, WebP, AVIF, SVG, GIF (first frame), and BMP. If your browser can display it, the tool can add transparent corners to it.
