Image Watermark

Put your name or logo on a photo

Image Watermark places text, such as a name, website or copyright line, or a logo image on top of a photo. You choose where it goes, how big and how see-through it is, and you see the result in a live preview before saving.

Everything happens in your browser with the Canvas API. The photo and the logo stay on your device.

How to watermark an image

1. Drop a PNG, JPG, WebP or GIF image on the upload area, or click it to choose one (up to 60 megapixels).
2. On the Text tab, type your watermark and set its size as a percentage of the image width, its colour and its angle: 0°, 45°, −45° or a custom angle between −90° and 90°. Or switch to Logo, choose a PNG, JPG or WebP logo and set its width.
3. Set Opacity (10–100 %) and the margin from the edges, then pick one of the nine positions or Tiled across the image.
4. Check the preview and click Download. photo.jpg is saved as photo-watermarked.jpg at its original size.

What the saved image looks like

• Same size: the watermark is drawn onto the full-resolution image; the preview is only scaled to fit your screen.
• Same format where possible: JPEG stays JPEG (quality 92 %), PNG stays PNG and WebP stays WebP. GIFs are saved as PNG, and an animated GIF keeps only its first frame.
• No metadata: the image is encoded again, so EXIF details such as camera model, date and GPS location are not carried over.

Who adds watermarks

• Photographers: mark proofs and portfolio images before sending or posting them.
• Online sellers: add a shop name to product photos used on marketplaces.
• Drafts and previews: tile “DRAFT” or “SAMPLE” across a design so it isn’t mistaken for the final version.
• Social posts: put a small handle or logo in a corner so a shared picture still points back to you.

Tips for a watermark that works

• Keep the soft shadow and outline switched on for text: it keeps white text readable on bright skies and dark text readable on shadows.
• For a logo, a PNG with a transparent background blends in; a JPG logo always brings its rectangular background.
• A watermark helps against casual copying but can be cropped out or painted over. A tiled, semi-transparent mark across the middle is harder to remove than a small corner one.
• Crop or resize first with Crop Image or the Image Resizer, then watermark, so the mark isn’t cut off or scaled afterwards. For documents, use Watermark PDF.

How placement and sizing work

Sizes that follow the image

Text size and logo width are percentages of the image width, and the margin is a percentage of the shorter side. The defaults — 5 % text, 20 % logo and a 3 % margin — look about the same on a small phone photo and a large camera file, so the same settings work across a batch done one by one.

Single position or tiled

A single watermark sits at a corner, an edge or the centre, kept inside the image by the margin even when it is rotated. Tiled repeats it in a staggered grid over the whole picture; there the margin slider adds space between the copies.
