About this free image watermarker tool
Add a centered text watermark to photos in a batch. Image tools prepare photos, screenshots and graphics for a specific destination. Pixel dimensions, aspect ratio, transparency and file format are separate decisions. Work from an original, inspect the exported image at its real display size and check that the destination accepts the output format before processing a large batch.
A practical example
Add a centered DRAFT label to several review photos with your chosen text color and font size.
Before you rely on the result
The watermark is visual, not ownership verification or secure redaction. Long labels are reduced to fit the image width.
