Frequently asked questions

Are my images uploaded?

No. They are measured in your browser.

What is the aspect ratio?

The shape of the image: width compared with height. 16:9 is wide screens, 1:1 is a square and 4:5 is a tall social post.

Where does the dpi number come from?

Some JPG and PNG files store a print resolution. If a file does not, it says No dpi saved. The pixel size is what matters for screens.

How big can I print an image?

A good print needs about 300 dpi. Divide the pixel width by 300 to get the width in inches, or use the print sizes shown.

Which formats work?

JPG, PNG, WebP, GIF, AVIF, BMP and SVG.
