How to use the Watermark Image
- Drop one or more photos on the box.
- Type your watermark text and/or choose a logo (a transparent PNG works best).
- Set size, opacity, rotation and position — or tile it across the whole image.
- Download the preview, or watermark every photo and download them as a ZIP.
Choosing a watermark style
| Style | Protection | Best for |
|---|---|---|
| Small corner text or logo | Low — easy to crop off | Branding social posts and portfolios |
| Centred, semi-transparent | Medium | Proofs sent to clients |
| Tiled diagonal pattern | High — hard to remove | Stock previews, documents, ID copies |
Tips
- Size is relative to the image width, so the watermark looks the same on every photo in a batch, whatever its resolution.
- Opacity around 40–60% stays readable without hiding the photo. Add the shadow for text on mixed light and dark backgrounds.
- Sending a copy of your passport or ID? Tile a watermark such as “Copy for Acme Bank rental application only” across it to limit misuse.
Create a logo-style badge with the favicon generator, resize photos first with the image resizer, and remove camera and GPS data with the EXIF remover.
Private by design
Your images are processed entirely in your browser with the Canvas API — nothing is uploaded, so personal photos, screenshots and client work never leave your device. There are no watermarks, sign-ups or file limits beyond your device’s memory.
Tools that pair well with the Watermark Image
- Image Cropper — Drag the frame or type exact pixels to crop a photo — square, 16:9, Instagram 4:5, Open Graph 1.91:1 or a perfect circle — then download it as PNG, JPG or WebP.
- Image Compressor — Shrink photos and graphics by 50–90% without visible quality loss.
- Add Watermark to PDF — Stamp text such as CONFIDENTIAL, DRAFT or COPY across every page, centred, diagonal or tiled — with a live preview before you download.
- Image to Base64 — Turn a PNG, JPEG, SVG, WebP or GIF into a Base64 data URI with copy-ready CSS and HTML — or paste a Base64 string to preview and download the image.
Frequently asked questions
Are my images uploaded?
No. Everything happens in your browser; the files never leave your device.
Can I watermark many photos at once?
Yes. The settings from the preview are applied to every photo, scaled to each image’s width, and downloaded as a ZIP.
Can I use my logo as a watermark?
Yes. Choose a logo — a PNG with a transparent background gives the cleanest result — and set its size and position. Text and logo can be combined.
Can a watermark be removed?
Small corner marks can be cropped or edited out. A tiled, semi-transparent watermark across the whole image is much harder to remove and the best deterrent.
