About Image Watermark Tool

Add a text or logo watermark to photos and ID copies. Set the size, opacity, angle and position, or repeat it across the whole image, and see a live preview. An ID copy preset marks Aadhaar or PAN copies with "Only for <purpose> – <date>" so they can't be reused. Several images can be done at once and saved as a ZIP, all in your browser.

How to Use

Add images

Drop, choose or paste one or more images (up to 30). The first one is shown in the preview; click a thumbnail to preview another.

Design the watermark

Choose Text or Logo, then set the size, opacity, rotation and layout (Single or Tiled). For ID documents, click "ID copy preset" and type the purpose.

Download

Click Download, or "Download all (ZIP)" for several images. Each image is created at full size in its original format.

JPG and WebP images stay in their format at the quality you choose, PNG stays PNG. "Save as" lets you pick another format.
Sizes are a percentage of each image's width, so the watermark looks the same on large and small photos.

Images up to 64 megapixels and 50 MB each. HEIC photos open only in browsers that support them.

Image Watermark Tool FAQ

How do I add a watermark to my Aadhaar copy?

Add the photo or scan of your Aadhaar card, click "ID copy preset" and type the purpose in place of <purpose>, for example "Only for HDFC Bank KYC". The text is repeated diagonally across the card at 30% opacity with today's date, so the copy can't easily be reused elsewhere. Then click Download.

Can I add a logo as a watermark?

Yes. Choose Logo, then pick a PNG, SVG or WebP image; one with a transparent background looks best. Set its size, opacity and position, or choose Tiled to repeat it.

Can I watermark many photos at once?

Yes. Add up to 30 images; the same watermark is applied to each, scaled to its width. Click "Download all (ZIP)" to save them together.

Are my documents uploaded to a server?

No. The watermark is drawn in your browser, so your ID copies and photos never leave your device.

Does adding a watermark reduce photo quality?

A JPG is saved again as JPG at the Quality you set (92% by default), which is close to the original. Choose PNG under "Save as" to avoid any further loss, at the cost of a larger file.
