Image Watermark Tool

Watermark a whole folder in one go

A watermark discourages casual copying, credits the author and turns every shared picture into a small advertisement. Doing it by hand for dozens of files is tedious, so this tool applies the same mark to a whole batch.

Steps

1. Drop up to 50 images onto the page. Click any thumbnail to preview it.
2. Choose Text or Logo.
3. For text, type the wording, such as a copyright line or a web address, and pick the font, colour, bold and outline. The outline keeps white text readable on bright areas and dark text on dark ones.
4. For a logo, upload a PNG with a transparent background. Wide logos are fitted inside the size you set.
5. Set the size as a share of the image width. That way the mark is the same relative size on a 800 pixel and a 6000 pixel photo.
6. Change opacity and rotation.
7. Choose a single mark and one of nine positions with a margin, or a tiled pattern with adjustable spacing.
8. Download the current image, or all of them as a zip.

Single or tiled

Use a single mark in a corner for portfolios, product photos and blog images, where a clean look matters. Use a tiled, slightly rotated pattern on proofs, stock previews and anything you do not want reused without permission, because it is hard to remove.

Tips

• Place corner marks where they will not cover a face or product detail.
• Keep marks readable but gentle. A mark that is too strong makes people ignore the picture.
• Output files stay in their original format: JPG stays JPG, PNG stays PNG and WebP stays WebP.
• Always keep your unmarked originals safe. A watermark cannot be reliably removed later.
