Watermark Image Online
Add a text watermark for client previews, portfolios, ecommerce images, and social posts. The selected image is composited in your browser.
A text watermark with position and opacity controls
Watermark Image Online adds a customizable text overlay to photos and graphics in the browser. You control the wording, color, size, position, and opacity, so the mark can range from a small attribution line to a prominent proof label. It can identify a brand or intended use, but it does not prevent copying, prove ownership, or replace a licence or rights-management process.
The selected images are composited in your browser and are not sent to our server for watermarking. The page may still make ordinary requests for assets, consent, analytics, advertising, or supporting code. Batch mode applies the same settings to each selected image; available memory and device speed determine how large a batch is practical.
Protection marks, branding marks, and when they hurt
Watermarks are commonly used for attribution and preview labelling. A corner mark keeps more of the subject visible but is easier to crop; text across part of the subject is harder to remove casually but also obscures more of the image. Either type can still be edited, so keep original files and any ownership or licensing records separately.
A large or opaque mark can distract from the image, while a faint mark may disappear when the picture is reduced. Match opacity and placement to the actual display size, inspect the preview, and check any marketplace or platform rules before publishing a watermarked listing.
PNG or JPG for a crisp watermark
JPG is the practical default for watermarked photographs; its compression is rarely visible on the mark at normal viewing sizes. If the watermark uses small text at low opacity and must stay pixel-sharp, export PNG, which saves the canvas exactly as drawn. WebP sits between the two when the destination supports it.
How To Watermark an Image Here
- Upload one or more images from your device using the file picker or drag and drop.
- Enter your watermark text — a brand name, social handle, or label like "PREVIEW" or "SAMPLE" — and adjust color, position, size, and opacity.
- Click Convert and preview the watermarked image to verify placement and visibility before downloading.
- Download the result and continue with compression, resizing, or sharing as needed.
Watermark Placement and Opacity Pitfalls
Setting opacity too high for branding watermarks, which makes the image look like a proof rather than a polished published asset.
Placing the watermark in a corner that gets cropped by social media platforms — test with the platform's actual crop before finalizing position.
Using a text color that blends into the image background, making the watermark invisible on certain photos. White text on bright images needs a shadow or darker color.
Applying large center watermarks to ecommerce product listings, which can reduce buyer trust and lower conversion rates on marketplaces.
Frequently Asked Questions
What can I control about the watermark text?
You type the words yourself, then set the position, text color, size in pixels, and opacity from 0.1 to 1. So you can stamp a brand name in a corner at low opacity, or drop a bold, semi-transparent SAMPLE across the middle. The preview updates as you adjust, so you can balance visibility against how much it covers the picture.
What opacity should I use so the mark deters copying without ruining the image?
It depends on intent. A subtle corner credit may work around 0.3 to 0.5, while a more visible proof label can use higher opacity and overlap the subject. Preview the mark at the final display size. A watermark can be cropped, covered, or edited and does not by itself prevent copying or establish ownership.
Can I add an image or logo as the watermark instead of text?
This tool applies a text watermark, so it stamps words rather than placing a logo file. You can approximate a brand mark by typing your name or handle and styling its color, size, and position. If you specifically need a graphic logo overlaid, compose that in an image editor after exporting from here.
