VTTC is a command line tool (CLI) that quickly converts various image and video formats into optimized formats compatible with popular VTTs (e.g. Foundry VTT, Roll20, Fantasy Grounds).

• Image conversion: any image into WEBP, PNG, JPEG, AVIF.
• Video conversion: any video into WEBM, MP4, OGG, MP3.
• Audio conversion: any audio into OGG, MP3.

1. Install Node.js 18 if you don't have it installed.
2. Run:

npm i vttc -g

(folder doesn't matter, it will install a Global package)

1. Open a command prompt in the directory with files you want to convert.

• Windows: Right Click -> Open in Terminal.
• Mac: see instruction.
• Linux: you already should know that.

2. Run:

vttc

npm update vttc -g
