How to watermark multiple images
- Choose up to 30 JPG, PNG or WebP images from your device.
- Enter your watermark text and optionally choose a logo. A transparent PNG is useful for a logo without a background.
- Choose one of nine positions, then adjust opacity, relative size and edge padding. The preview shows the first readable image.
- Select JPG or PNG and a maximum output edge. Click Watermark all images, then download individual files or the ZIP.
Text and logo placement that scales with your images
Watermark width and edge padding are calculated from each image’s shorter side. A logo keeps its proportions, and optional text sits beneath it. Your images keep their aspect ratio and are never enlarged. Images larger than your selected output limit are reduced proportionally.
Frequently asked questions
Are my images uploaded?
No. The tool decodes images, draws the watermark and creates downloads in your browser. Your selected images and logo are not uploaded for processing.
Can I use only a logo?
Yes. Choose a logo and clear the watermark text. You can also use text alone or place text beneath the logo.
Should I choose JPG or PNG?
JPG usually gives smaller photo files and places transparent areas on a white background. PNG preserves transparency and uses lossless encoding, but the files can be larger. Resizing and watermarking still change the image itself.
What are the limits?
Choose up to 30 images, with a maximum of 20 MB per file, 150 MB combined and 24 megapixels per image. Logos can be up to 8 MB and 4 megapixels. The maximum output edge is 4096 pixels, with up to 24 MB per result and 64 MB of results in one batch. Large batches work better with JPG or a smaller output size.
Does a watermark prevent all copying?
A visible watermark can identify your brand or credit on an image. It does not prevent downloading, editing or copying the image.
