Frequently asked questions

What is Smart Fit?

Smart Fit is a crop mode that prevents important parts of your image from being cut off. Instead of cropping, it scales your image to fit the container and fills the empty edges with a blurred version of the same image.

Are my images processed securely?

Yes, 100% of the image processing happens locally in your web browser. No images are uploaded to any server.

Should I use JPEG or PNG?

For photographs and complex gradients (typical hero banners), use JPEG. It offers much smaller file sizes. For illustrations, graphics with text, or when you need lossless quality, use PNG.

How do I use these images with HTML srcset?

Use the <picture> element or srcset attribute to serve different sizes based on viewport width.

Which browsers support this tool?

Any modern browser with HTML5 Canvas support.

What source image size should I upload?

Start with the largest practical source image you have, then export the required variants. A larger source gives the crop more room for different hero ratios.

Does Smart Fit remove important subjects?

Smart Fit avoids aggressive cropping, but it cannot understand every subject automatically. Review the preview and use the crop controls when a face, logo, or product needs precise placement.
