How does the resizing work?
Your image is resized using a 'cover fit' approach — it fills the target dimensions completely, cropping from the center if needed. This ensures no empty space.
Can I download multiple sizes at once?
Yes! Select all the sizes you need and click Download. Each size is saved as a separate PNG file.
Are my images uploaded anywhere?
No. Everything runs in your browser using the Canvas API. Your images never leave your device.
