The settings screen with the position grid, size and opacity controls.
Thenaynhe Watermark is a small set of media tools that run when images enter your site.
Watermark on upload
Stamp a watermark image (such as your logo) onto JPEG, PNG and WebP uploads automatically. Pick the placement on a nine-cell grid, set the size as a percentage of the image width, and choose the opacity. Transparent PNG watermarks stay transparent.
Strip metadata
Remove EXIF and other embedded metadata from uploaded images, including camera model and GPS coordinates. The image is re-encoded on upload, which drops the metadata.
Rename files after the post title
Images uploaded from inside the post editor can be renamed using the slug of the post they belong to, so a post titled “Cách làm bánh” produces cach-lam-banh.jpg. Uploads from the Media Library screen keep their original names.
Import external images
When a post contains images hosted on other sites, an “External Images” box in the editor shows how many were found and offers a button to copy them into your Media Library. The links in the post are rewritten to the local copies.
The importer only runs when you click it, it works on the saved post content, and it uses the WordPress download routines, which refuse requests to internal addresses.
Good to know
- The watermark is written onto the uploaded file and cannot be removed later. Test with a sample upload first.
- Stripping metadata is also permanent for the uploaded copy.
- Only the original uploaded file is processed. The intermediate thumbnail sizes that WordPress generates are not watermarked.
- WebP support depends on the server. The settings screen tells you if it is missing.
