Watermark Image
Add your name or brand. Adjust position, colour, size, and opacity.
Your files never leave your deviceHow to use Watermark Image
Add a readable text credit, brand, or ownership notice to photos. Apply the same proportional watermark to a batch, with a live preview of the first image.
- Choose your images and enter up to 100 characters of watermark text.
- Set the text colour, opacity, size, position, and optional tiled repetition. Size and margins scale with each image.
- Review the preview for contrast and placement, then export individual files or one ZIP.
A practical example
Use © Team Hypomnema in the bottom-right corner at 65% opacity, or use tiled repetition for a visible proof image.
Before you share the result
- Place the watermark away from important faces, text, or product details.
- The preview uses a system sans-serif font; character appearance depends on installed fonts.
- A visible watermark is a label, not a guarantee against copying or removal.
Useful things to know
Are my files private?
File processing happens locally in your browser. Images, PDFs, and output archives are not uploaded to our servers. Save your results before leaving: the workspace is cleared on refresh or navigation.
What formats and sizes are supported?
Up to 30 images, 30 MB per file, 80 MB combined, and 40 megapixels per input image. Dedicated format converters accept only their named source format. Exported images are limited to 16 megapixels. Total output is limited to 100 MB. Smaller batches work better on phones.
What should I expect from this tool?
This tool adds text watermarks, not uploaded logos or invisible digital watermarks. Watermarks are permanently drawn into exported pixels.
Will the exported image look exactly like the original?
PNG retains the decoded pixels without extra lossy compression; JPEG and WebP use the chosen quality. Metadata and colour profiles are not copied. Colour rendering can vary by browser. Animated images become a browser-decoded still frame. Keep your originals and inspect the downloaded output.
Is Watermark Image free, and how is my privacy handled?
Yes. Watermark Image is free to use without registration. Tool inputs are processed in your browser rather than uploaded to our servers. Optional usage analytics follows your cookie preferences; it does not receive your files or tool inputs. Keep your browser updated and review results before sharing.
