Watermarking is one of the most effective ways to protect your visual content online. Whether you are a photographer sharing client proofs, a designer publishing portfolio pieces, or a content creator posting original graphics, a watermark ties your identity to your work and discourages unauthorized use.
This free image watermark tool runs entirely in your browser. You can add text watermarks with custom fonts, colors, and sizes, or overlay your own logo as an image watermark. Adjust opacity so the mark is visible without distracting from the image itself, choose from nine positioning options, apply rotation for a diagonal stamp effect, or tile the watermark across the entire canvas for maximum protection. No account required, no file uploads to external servers, and no limits on how many images you process.
Unlike desktop software that requires installation and often a paid license, this tool is available instantly from any device with a modern browser. Your images stay on your machine throughout the entire process, making it a privacy-friendly choice for sensitive or unreleased work.
A text watermark is the simplest option. You type a string -- typically a copyright notice, your name, your website URL, or a phrase like "SAMPLE" or "PROOF" -- and the tool renders it directly onto the image. Text watermarks are fast to set up, easy to change between images, and work well when you need a clean, no-fuss mark. You have full control over the font, size, and color, which means you can match the watermark to your brand style without needing a separate logo file.
An image watermark (also called a logo watermark) uses a separate graphic file as the overlay. This is the better choice when you have an established brand identity and want every watermarked image to carry your exact logo, signature, or monogram. Image watermarks tend to look more professional and are harder to replicate, since removing a complex graphic is more difficult than cloning over flat text. The tradeoff is that you need a prepared logo file -- ideally a PNG with a transparent background so only the logo shape appears on the image.
Many professionals use both approaches depending on context: a logo watermark for published portfolio images and a text watermark reading "PROOF" or "NOT FOR PRINT" on client preview deliveries.
Where you place a watermark matters almost as much as the watermark itself. A poorly positioned mark can be easily cropped out, or it can obscure the most important part of your image.
A watermark is a visual deterrent, not a legal instrument. It signals ownership and makes casual theft inconvenient, but it does not replace proper copyright registration or licensing agreements. In most jurisdictions, copyright is automatic the moment you create an original work, but registering it with your country's copyright office gives you stronger standing if you ever need to pursue a legal claim.
For working photographers and designers, watermarking is one layer in a broader protection strategy. Other layers include embedding EXIF metadata with your name and copyright notice, using reverse image search services to monitor where your images appear, serving low-resolution versions on public-facing pages, and including clear usage terms on your website.
If you discover someone using your watermarked image without permission, the watermark itself serves as evidence of ownership. Most platforms have DMCA takedown processes that allow you to request removal of infringing content, and a visible watermark in the stolen copy strengthens your case.
Watermarking is especially important for client proofs and preview galleries. Delivering unwatermarked full-resolution images before payment is finalized is one of the most common mistakes freelance creatives make. A center-placed or tiled watermark on proof images protects your leverage while still letting the client evaluate the work.
A watermark is a visible overlay placed on an image to indicate ownership, branding, or usage restrictions. It can be text (like a copyright notice or your name) or a graphic (like a logo or signature). The term originates from papermaking, where a faint design was pressed into wet paper to identify the manufacturer. In digital imaging, watermarks serve the same purpose: they mark the image as belonging to a specific creator or organization.
Watermarking discourages unauthorized use of your images by making it clear who owns them and making the image less useful to anyone who copies it without permission. It is especially valuable for photographers sharing client proofs, artists posting work on social media, and businesses publishing product images. Even if someone screenshots or downloads your image, the watermark stays attached, providing a persistent attribution link back to you.
The watermark itself is rendered onto the image pixels, so the output file is a modified version of the original. However, the underlying image data remains at full resolution and quality. This tool exports watermarked images as PNG files, which use lossless compression, so there is no additional quality loss from the save process. The only visual change is the watermark overlay itself.
It depends on your goal. For branding, a small semi-transparent mark in the bottom-right corner is standard and unobtrusive. For theft prevention, center placement or full-image tiling is far more effective because the watermark cannot be cropped out. For client proofs, center placement over the main subject ensures the image cannot be used without payment while still being fully evaluable.
Simple watermarks in corners can be cropped away. More sophisticated watermarks placed over detailed areas of the image can sometimes be reduced using clone tools or AI inpainting, but this is time-consuming and rarely produces a clean result, especially with tiled watermarks. No watermark is completely removal-proof, but a well-placed watermark significantly raises the effort required to steal your work, which is usually enough to deter casual theft.
Text watermarks are quick and flexible -- you can change the text for each image or batch without needing a separate file. Logo watermarks look more professional and are harder to replicate or remove because of their complex shapes. If you have an established brand identity with a logo, use the logo. If you need something fast or want to include variable information like a copyright year or client name, use text.
For branding purposes, 20% to 40% opacity strikes a good balance between visibility and subtlety. The watermark is noticeable enough to identify you as the creator but does not dominate the image. For proofs or stronger protection, 40% to 60% is more appropriate because the goal is to prevent unauthorized use rather than to look elegant. Go above 60% only if you want the watermark to be impossible to ignore.
This tool accepts JPEG, PNG, WebP, and BMP files as input. The watermarked output is saved as a PNG file, which preserves full quality with lossless compression. If you need the result in a different format, you can use a separate image converter tool after watermarking.
Because all processing happens in your browser, the practical limit depends on your device's available memory. Most modern computers and phones handle images up to 20-30 megapixels without issues. Very large files (such as raw camera output above 50 megapixels) may cause slowdowns on older devices. There is no server-side file size restriction since nothing is uploaded.
This tool processes one image at a time. For batch watermarking, you would need to repeat the process for each image. The settings (text, font, opacity, position) persist between images, so you can quickly load a new file and download the result without reconfiguring everything. Desktop applications like Adobe Lightroom or dedicated batch tools are better suited for watermarking hundreds of images in a single run.
Yes. The tool runs in any modern browser, including Safari on iOS and Chrome on Android. The interface adapts to smaller screens. You can upload images from your phone's camera roll or files app, apply a watermark, and save the result directly to your device. Performance depends on your phone's processing power, but most recent smartphones handle it smoothly.
No. This tool is 100% browser-based. Your image is loaded into your browser's memory using JavaScript, the watermark is applied on an HTML canvas element, and the result is downloaded directly from the canvas. No image data is transmitted to any server at any point. This makes the tool safe for confidential, unreleased, or sensitive images.
The tool offers a curated selection of web fonts including Inter, Arial, Georgia, IBM Plex Mono, Courier New, and Impact. These cover a range of styles from clean sans-serif to monospaced and display faces. Custom font uploads are not currently supported, but the available options provide good flexibility for most branding needs.
For corner-placed text watermarks, a font size that takes up roughly 3-5% of the image width is a good starting point. For logo watermarks, 15-25% of the image width is typical for corner placement, and 10-15% works well for tiled patterns. The right size depends on your image resolution and how prominent you want the watermark to be. Use the live preview to dial it in visually.
If you are using a logo watermark, prepare your logo as a PNG file with a transparent background. When the tool overlays it onto your image, only the logo shape will appear -- the transparent areas will show the image beneath. For text watermarks, transparency is handled automatically; only the text characters are rendered, with no background box behind them.
Social media platforms compress and resize images, which can degrade small or fine-detailed watermarks. Use a slightly larger and bolder watermark than you would for print or web use. Place it away from edges that might get cropped by different platform aspect ratios (for example, Instagram crops to square in grid view). A center-bottom or lower-third position tends to survive cropping across most platforms. Keep the text or logo simple enough to remain legible after compression.
If you own the original image and the watermark content (your name, your logo, your copyright notice), you can use the watermarked output however you like, including commercially. The watermark is applied by you to your own content. Just make sure your watermark does not include trademarks, logos, or text that belongs to someone else unless you have the right to use them.
Copyright is a legal right that protects your creative work from being copied or used without your permission. In most countries, copyright is automatic the moment you create an original work. A watermark is a visual marking on the image itself -- it signals ownership but does not create or confer any legal rights. Think of a watermark as a "no trespassing" sign: it communicates your claim, but the legal protection comes from copyright law, not from the sign itself. Both work together: copyright gives you the legal standing, and the watermark makes your claim visible.
You can apply a watermark, download the result, then upload the watermarked image again and apply a second watermark on top of it. For example, you might first add a tiled text watermark for protection, then add a logo in the corner for branding. Each round preserves the previous watermark as part of the image, so you can layer as many as you need.
The tool requires an initial page load from the website, but once the page is fully loaded, all processing happens locally in your browser without further network requests. If you lose your internet connection after the page has loaded, the watermarking functionality will continue to work for that session. However, you need to be online to initially load the page.
