Transforms allow you to change the content of the scan before further processing by using JavaScript's String.replace.

The input pattern is any valid JavaScript regular expression. Delimiters, i.e. leading and trailing /, are not needed.

The output can use $& for the entire matched expression, $1 for the first capture group, $2 for the second capture group, etc.

Scanned content and image data (image/webp data URI) will be sent to the URL specified below.

If the URL is on another domain, it needs to have CORS enabled to POST from the current domain.
