Can I compress a WebP to a specific file size?

Yes. Pick 'Target size', enter a KB value, and the tool adjusts the WebP quality in your browser until it fits.

What if my browser can't save WebP?

Some browsers can't encode WebP. If yours can't, the tool automatically saves a smaller JPEG instead — still fully private.
