What local watermarking means
The image is loaded, previewed and rendered inside the browser. The tool exports the watermarked result without sending the original file to a remote image-processing service.
Documents that benefit from local processing
ID photos, passports, driver licenses, certificates, diplomas, business licenses, contracts and onboarding files are good candidates.
Why a browser extension is convenient
It sits close to your upload workflow. You can prepare a file before upload or use an in-page insertion flow where supported.
Privacy is still a workflow
Local watermarking helps reduce unnecessary uploads, but you should still verify recipients, store files carefully and avoid sharing more information than needed.
