How to add your name or logo to a picture

QUICK ANSWER

Choose the pictures and the watermark type. Keep an unmarked original so you can make a clean version later if needed. Apply the watermark and download the new images.

A small credit or brand mark can identify a picture when it is shared. Watermark Image lets you add a text or image mark, then check how it sits over the photograph.

1. Open your file

Choose the pictures and the watermark type. Keep an unmarked original so you can make a clean version later if needed.

2. Work through the settings

  1. Enter the watermark text or choose the logo image. Use a mark you have the right to use.
  2. Adjust the position, size, color and other available styling controls.
  3. Check the mark against both light and dark parts of the photo. A readable but restrained mark is often more useful than an oversized one.
  4. Apply the watermark and download the new images.

3. Check before you share

  • Read the mark at a normal viewing size.
  • Check that it does not cover a face, signature or important detail.
  • Review the placement on images with different proportions.

Questions you may have

Can I keep a version without the mark?

Keep your original image separately. The tool creates a new output rather than overwriting that source file.

Can I use one placement on every picture?

You can use shared settings, but review the results. A position that is clear on one photo may cover the subject on another.
