ImageMagick / cwebp vs a Browser Batch Converter

If you already have a Makefile, use `cwebp`. If you are a photographer, marketer or PM, installing ImageMagick is the wrong first step. The browser converter is the same destination format with a drop zone and a savings total.

CLI is not a UX

Engineers overestimate how many people will run a for-loop. A $9 PRO ZIP is how the other 90% finish the job.

Why it matters

  • Windows PATH pain.
  • No preview of 'you saved 14 MB'.
  • CI still should use CLI or the API.

How to do it

  1. Developers: cwebp -q 80 -resize 1600 0 in.jpg -o out.webp.
  2. Everyone else: drop the folder here.
  3. Do not make the intern install MSYS2 for a banner pack.

API middle ground

The WebP API is for servers that should not shell out to ImageMagick.

Convert a batch in your browser. Nothing is uploaded.
