Square, Wide, PNG, what to choose ?
The short answer: it depends.
We support most extensions (PNG, GIF, JPEG/JPG to name a few).
We accept all sizes.
We don't process images (we don't improve them, we don't crop them, we don't reduce the quality for you).
So if you want to use a 4K image: that's up to you.
This is true on the 15th of August 2022. We may change this behavior at some point to reduce the size, improve download times, crop the image if needed, etc.
Now: bear in mind that your guests maybe on a low bandwidth internet connection or use a small phone.
That being said: the best thing to do today is to test using the "Preview tab" and check that your selected images react the best way in all situations. (And in particular in the situations you expect your guest to answer the interview).
You can select multiple layout options in the Theme tab:
And you can switch the preview mode on the left, above the preview:
Last, and it's very important to understand: we hide images on mobile. Unless you force them to be displayed with the toggle here:
If anything is unclear: just ping us on the help chat ;)
