Digikey has a free online schematic drawing tool. I've used it a couple of times and it's easy. You can download the files as a PNG file (and maybe other formats.). And you can save it for future editing.
You might have to sign-up for an account but they don't spam you.
For designing PC boards (and making associated schematics) I just used DesignSpark to make my first "computer designed" PCB. (Many years ago I did it by hand,) Then I had it fabricated in China via Seed Studio.
My only complaint with DesignSpark is that a lot of the schematic symbols are just boxes/rectangles with leads. (But you can make your own schematic symbols.) Oh, you also have to sign-up for an account and it logs-on every time you start the application, but it's free and it works and they also don't spam you.
I tried Eagle and KiCad but I got REALLY frustrated just trying to make a custom part from a similar existing part already in the library. I'm sure they are OK once you learn to do it, but trying to learn on my own it seemed "too hard". (This was for schematic and PCB design where the part has to be defined and linked for both.)
