> COBALT
this is probably the absolute most trustworthy youtube to mp4/mp3 site in existence. it has a decently sized list of supported sites from which you can download stuff, including but not limited to youtube, twitter, and soundcloud. it's made by the people who made meow.camera.

> IMAGE RESIZER
this is what i use for resizing and compressing images. it's probably trustworthy? idk.
