Add a text or logo watermark locally
How to use it
Add an image, type the watermark text or choose a logo, place it, set the opacity, and export the preview. Use a copy. The original should stay unmarked until you like the result. The export is a picture made in the browser. It is not uploaded. A watermark is not redaction. The picture underneath is still in the file in a visual sense, and a faint mark does not hide an account number. If you need text removed from a PDF, use redact. Check the edges of the export so the mark is not cut off.
The file stays in this browser. NexTool does not upload it and does not keep a copy after you leave the page. Download the result and check it before you send it on. If the tab runs out of memory, the job stops and the original is still the one on your computer.
