What is an image watermark tool?

An image watermark tool adds visible text, a logo, or a repeated mark on top of a photo or graphic. People use a watermark image online workflow when they need to label client proofs, share draft designs, identify brand assets, mark samples, or add a light ownership note before publishing. ConvertorLab works as a photo watermark maker for practical browser tasks: add watermark to image, add watermark to photo, place a logo watermark, create a transparent watermark, adjust opacity and rotation, and export the result without opening a heavy desktop editor.

Example watermark workflow

If you are preparing preview photos for a client, add a small logo watermark near the corner, lower the opacity so the image remains readable, and export the finished files together.

How to make a watermark look clean

A good watermark is readable without fighting the image. For photos, use moderate opacity, a corner position, and enough margin so the mark does not touch the edge. For screenshots or product images, a small logo watermark or short text watermark often works better than a large repeated pattern. For previews and samples, tile mode can help, but keep the opacity low so the subject is still easy to inspect. If the image will be uploaded to a website, resize and compress after watermarking so the final file matches the destination size.

Add watermark questions

How do I add a watermark to an image online?

Choose an image, select text or image watermark mode, adjust the watermark position, opacity, scale, and rotation, then download the finished image.

Can I add a logo watermark to a photo?

Yes. Switch the watermark type to image, upload your logo, then place it on the photo and adjust opacity, scale, rotation, and blend mode.

Can I add a text watermark to a photo?

Yes. Use text watermark mode, type your wording, then adjust font, size, color, outline, shadow, background box, opacity, and placement.

Does this tool support batch watermark photos?

Yes. Add multiple images, use one watermark setup, then download the current image or export the batch as a ZIP.

Can I watermark JPG, PNG, and WebP images?

The tool accepts common browser-supported image files including JPG, PNG, WebP, and HEIC where browser decoding is available. Output can be PNG or JPEG.

Can I make a transparent watermark?

Can I tile a watermark across an image?

Yes. Enable tile mode and adjust horizontal spacing, vertical spacing, and tile angle when you want repeated text or logo marks across the image.

Will a watermark protect my photo from every kind of copying?

No. A watermark can discourage casual reuse and identify draft or branded images, but it is not a full copyright protection system.
