Here is everything you need to know about our converter.

Yes, completely free. There are no hidden fees, subscriptions, or watermarks placed on your final image.
No. The entire conversion process happens locally within your web browser using HTML5 technology. We never see, save, or store the files you select.
You can upload most standard image formats including JPG, PNG, and WebP. The final downloaded file will be provided as a high-quality PNG.
This tool forces the uploaded picture into an exact 300x300 dimension (a 1:1 perfect square). If your original photo is a tall portrait or a wide landscape, it will look stretched. Start with a photo that is already relatively square for the best result.
It is a widely used dimension for profile avatars, small product thumbnails, and standard website photo grids.
Absolutely. The tool is fully responsive and works directly inside your mobile browser on iOS and Android devices.
