Why use local browser tools
Local browser workflows reduce exposure for private files because the main processing path runs on your device instead of starting with an upload to a third-party service. That is useful when the document, image, text, or encoded payload contains work material, customer data, or anything you would rather review locally before sharing.
Browser-based tools are also direct. You open the file, run the operation, and download the result without waiting for remote queues or account-gated limits. You can review Plain.tools privacy claims in Verify Claims.
