How it works
How to use Watermark Image
Design a readable watermark
Type your name or choose a logo. Adjust width, opacity, rotation and position, or repeat the mark across the image. The preview shows the first photo; settings scale with each photo’s dimensions.
Export copies and inspect the batch
Save PNG to keep transparent areas, or JPG with a chosen background. Download each photo or the batch ZIP. Check both landscape and portrait photos before publishing.
FAQ
Good to know
How do I use Watermark Image?
1. Select the photos you want to share: Choose JPG, PNG or WebP files from your device. Keep the original photos separately so you always have an unmarked copy. 2. Design a readable watermark: Type your name or choose a logo. Adjust width, opacity, rotation and position, or repeat the mark across the image. The preview shows the first photo; settings scale with each photo’s dimensions. 3. Export copies and inspect the batch: Save PNG to keep transparent areas, or JPG with a chosen background. Download each photo or the batch ZIP. Check both landscape and portrait photos before publishing.
Does a watermark prevent copying?
No. A visible watermark can identify a source or label a preview, but it can be cropped or altered. It is not encryption, a digital signature or proof of ownership.
Can I use a transparent logo?
Yes. Choose Logo watermark and select a PNG, JPG or WebP logo up to 5 MiB and 4 megapixels. PNG is useful when the logo needs a transparent background.
Will the photos keep their original dimensions?
Yes, within the 40-megapixel limit. The preview is smaller for display, but exports use the decoded pixel dimensions. Original metadata is not copied, and JPG export uses lossy compression.
Do my photos or logo leave my device?
No. Watermarking runs in your browser. Up to 20 photos, 25 MiB each and 100 MiB per batch are supported. Download your copies before clearing the batch or closing the page.
