About this tool
Apply ownership, draft, client, or campaign labels consistently across a batch of images without uploading private assets.
Image Watermark applies the same rendered text style to a batch of raster images and exposes final previews before individual or ZIP download.
- Shows a live preview for the selected image and applies the same fitted watermark to up to 30 local files.
- Controls nine positions, relative text size, edge padding, color, contrast outline, opacity, and PNG, JPEG, or WebP output.
- Automatically reduces oversized watermark text to remain inside each image or reports a file-specific error instead of silently clipping it.
- Decodes every successful output to verify its MIME type and dimensions, then provides individual downloads or a collision-safe ZIP with a manifest.
How to use Image Watermark
Add PNG, JPG, or WebP images, set text, position, opacity, relative size, color, and output format, then generate and inspect the results before downloading.
When this tool is useful
- Before sharing draft photography or client proofs.
- When campaign images need a consistent ownership label.
- When several assets require the same status or review mark.
Practical tips
- Choose a contrasting color and inspect light and dark image areas.
- Keep opacity high enough to remain visible after resizing.
- Retain unwatermarked originals for future editing.
Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Mark a proof gallery
Example input
12 JPG files; text DRAFT; centered; 45% opacity
Expected output
12 watermarked previews and one downloadable ZIP.
Centered watermarks are harder to crop out but cover more of the image.
Validation checklist
- Inspect every output preview.
- Confirm watermark spelling, color, position, and opacity.
- Check JPG output for visual quality.
- Keep original images separately.
