Frequently asked questions

Can I enlarge a small photo?

Yes, but enlarging cannot invent missing detail. The result may look soft. It is usually better to start from a larger original.

How do I convert PNG to JPG?

Open the PNG, keep the size or set new dimensions, choose JPG as the format, and download. Transparent areas become a white background in JPG.

Does this crop the image?

No. It scales the whole image. If you need a specific crop, resize so the short side fits, then crop in your editor. A dedicated crop tool can be added later.

Are files uploaded?

No. Resizing and conversion happen on your device.
