Ffmprg is remarkably powerful. If it is a picture on your screen, you can use ffmpeg to do what you want to it. Recently discovered it could convert PNG, jpeg, and webp images back and forth. To think I’ve only used it for video.

Y can act as a consonant or a vowel, depending on the position in the word.

Definitely a vowel: Baby

Part of a vowel sound: Play

Not a vowel at all: Yes, lawyer

When a Y starts a syllable, it typically doesn’t take a vowel sound, closer to a “soft j” sound.
