Add a text or logo watermark to your photos, with control over position, size, opacity and rotation. Free, runs entirely in your browser, and it never stamps a watermark of its own on your work.
The imgbox Add Watermark tool lets you watermark your photos online for free by overlaying text or an image logo directly onto your pictures. Protect your work, add branding, or mark a proof by placing a custom watermark exactly where you want it, all inside your browser. Because the watermarking happens on your device, your original images and your logo are never uploaded, and there is no account, no watermark from us, and no limits.
A watermark is text or a logo placed over an image to show ownership, add branding, or discourage unauthorized reuse. The imgbox watermark tool supports both kinds: type a text watermark such as your name, website, or copyright line, or overlay an image watermark like your brand logo or signature. You position it over your photo, adjust it, and export the finished image.
All of this runs client-side. Your photo and your logo file are read into the page, combined on an in-memory canvas, and returned to you as a single flattened download. Nothing is transmitted to a server, so even unreleased photography, client proofs, and branded assets stay completely private on your machine, and the tool keeps working offline once loaded.
Watermarking is the simplest way to attach your identity to an image before you share it publicly. For photographers, designers, and creators, a visible watermark deters people from passing off your work as their own and acts as free advertising: anyone who sees the image also sees your name or website. For businesses, a logo watermark reinforces brand recognition every time the image is shared or reposted.
Watermarks are also practical for everyday protection. You can mark proofs and previews you send to clients so full-resolution unmarked versions stay behind a paywall, label screenshots and documents as confidential or draft, or stamp product photos so they trace back to your store even when they spread across the web.
A text watermark is quick and flexible: it is ideal for a copyright line, a website address, a photographer's name, or a status label like DRAFT or CONFIDENTIAL. Because it is generated from text, it stays crisp at any size and needs no separate file. Text watermarks work best when you want a clear, readable claim of ownership.
An image watermark uses a graphic you provide, most often a brand logo or a handwritten signature. It is the right choice when your identity is tied to a specific mark rather than plain words. For the cleanest result, use a logo with a transparent background (a PNG) so only the logo shape appears over the photo instead of a solid rectangle.
Placement is a trade-off between visibility and getting in the way of the picture. A corner watermark (commonly the bottom-right or bottom-left) is subtle and keeps the main subject clear, but it can be cropped out by anyone determined to remove it. A centered or repeated watermark across the middle of the image is much harder to crop away, which is why it is preferred for proofs and high-value photos, at the cost of covering more of the picture.
The most effective watermarks are semi-transparent so the image underneath still reads clearly while your mark remains legible. A watermark that is too solid ruins the photo, while one that is too faint is easily ignored or cloned out. Aim for a balance where the mark is obvious enough to identify you but light enough that the image is still enjoyable.
The goal of a good watermark is to be noticeable but not overwhelming. Match the watermark's scale to the image: a tiny mark on a large photo is easy to miss, while an oversized one buries the subject. Keep colors neutral, often white or black with reduced opacity, so the watermark reads over both light and dark areas of the picture.
Consistency matters for branding, so use the same watermark style, size, and position across a set of images to build recognition. Because imgbox flattens the watermark into the exported image locally, the mark becomes part of the picture and cannot be toggled off by whoever downloads it, all while your originals stay private on your device.
Open the imgbox Add Watermark tool, add your photo, then add a text or logo watermark, position it, and download the result. It is completely free with no account, and because it runs in your browser your photos are never uploaded.
Reduce the watermark's opacity so the photo underneath still shows through, or upload a logo saved as a transparent PNG so only the logo shape appears with no background box. A semi-transparent mark stays visible while keeping the image readable.
Yes. Choose the image watermark option and add your own logo or signature file. For the cleanest look use a PNG with a transparent background so no solid rectangle appears around your logo.
Select the text watermark option and type your text, such as your name, a copyright line, or your website URL. Text watermarks stay sharp at any size and are ideal for a quick, readable claim of ownership.
No. imgbox combines your photo and watermark entirely inside your browser, so neither your image nor your logo is ever sent to a server. This keeps client proofs and unreleased work completely private.
A bottom corner is subtle and keeps the subject clear but can be cropped off, while a centered watermark is much harder to remove and best for proofs and high-value images. Keep the mark near your subject so it cannot simply be cropped away.
Not if you keep it balanced. Use reduced opacity and a size that suits the image so the watermark is clearly visible but the photo underneath is still enjoyable. A mark that is too solid overwhelms the picture, while one too faint is easy to ignore.
The watermark is flattened directly into the exported image, so it becomes part of the picture and cannot be toggled off by whoever receives it. Keep your unmarked original safe on your own device for your records.
No. The tool runs in your web browser with no account, no installation, and no watermark added by us. Once the page has loaded it even works offline, since all the processing happens locally on your device.
