IMAGE PROTECTION & BRANDING
Why Add a Watermark to an Image?
A watermark is a simple way to mark ownership on an image before it goes out into the world. Photographers use it to protect portfolio previews, businesses use it to brand product photos, and pretty much anyone sharing original work online uses it to make casual reposting or theft at least a little less appealing — or to make it obvious where a reposted image actually came from.
It's not a bulletproof anti-theft measure, to be honest — someone determined enough can crop or remove a watermark. But for casual protection, brand consistency across a batch of images, or just making sure your name travels with your work when it's shared, watermarking does the job well.

TEXT WATERMARKS
Adding a Text Watermark
How to add text to an image as a watermark: type in whatever you want displayed — your name, business, website URL, or a copyright notice — and place it wherever fits best on the image. Common choices are a corner (less intrusive, easier to crop out though) or diagonally across the center (more visible, harder to remove cleanly). Adjust opacity so it's noticeable without completely obscuring the photo underneath — a very light, semi-transparent watermark often looks more professional than a bold, opaque one.
LOGO WATERMARKS
Adding a Logo Watermark
How to add a logo watermark to a photo: upload your logo file (a PNG with a transparent background works best here, so you don't end up with an ugly white box around your logo) and place it on your image the same way you would a text watermark — corner placement is the most common choice for logo watermarks, since it reads clearly as a brand mark without dominating the photo.
TRANSPARENCY CONTROL
Adding a Transparent Watermark
How to add a transparent watermark to a photo: this just means adjusting the opacity setting down so the watermark blends into the image rather than sitting as a solid, opaque overlay. Most watermarking tools, including this one, let you control transparency directly — lower opacity for a subtle brand presence, higher opacity if you specifically want the watermark to be hard to miss or hard to remove.
COPYRIGHT PROTECTION
Adding a Copyright Watermark
How to add a copyright watermark to images: this is really just a specific type of text watermark, typically formatted with a copyright symbol, your name, and the year — something like "© 2026 Your Name." It works the same as any text watermark; the format is just a convention that clearly signals copyright ownership rather than just branding.
BATCH PROCESSING

This is especially useful for watermarking product photos consistently across an entire store listing, or branding a whole photography portfolio in one pass instead of repeating the process image by image.

Upload several images together instead of one at a time.

Set your watermark (text or logo) and positioning once.
Instant batch application
The tool applies the same watermark across every image in the batch.
