Resizing photos for social media should be a cinch, but most editing programs are a pain to use. Of the dozen I’ve used, Instasize is the fastest, easiest and most consistent...

Yes. A batch can mix JPG, PNG, WebP, and browser-decodable AVIF sources, and every result uses the one output format you select.
