AVIF uses the AV1 video codec to compress images, with transparency and high dynamic range colour.
Strengths: It is usually the smallest at equal quality, often half the size of a JPG.
Limits: Encoding is slow and many desktop apps still cannot open it.
PNG stores images losslessly: every pixel stays exactly the same, and it supports a transparent background.
Strengths: Great for screenshots, logos, charts and any image with text or sharp edges.
Limits: For photographs it is much larger than a JPG or a WebP.

Your device’s memory sets the limit: on desktop, images up to about 100 megapixels; on mobile, up to 16.7. If an image is too large you are told before it starts.
Yes. Drop as many AVIF files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each PNG or all of them in a ZIP.
