About this tool
Adding a text watermark before sharing photos online protects attribution - particularly important for portfolio images, product photography, and original artwork. Once a clean image is shared publicly, removing the attribution is easy; watermarking before sharing is the reliable preventive step.
This tool adds a text watermark only, positioned at one of five fixed spots with adjustable size, color, and opacity, all rendered locally in your browser.
Upload any image, type your watermark text, choose one of five fixed positions - the four corners or center - and set font size, color, and opacity, then download the watermarked PNG. All processing happens in your browser; no image is uploaded to any server.

Common Workflows
Brand a Photo Before Sharing
Type your name, business, or @handle as the watermark text and place it in a corner before posting photos publicly.
Mark a Portfolio Image Off-Center
Position the watermark over the center of the subject rather than a corner - it's harder to crop out and better deters casual reuse.
Mark a Document as a Draft or Sample
Type "SAMPLE" or "DRAFT" as the watermark text at a high opacity to mark a document shared for review.
Remove the Background First for a Clean Brand Mark
To brand a logo or product cutout rather than a full photo, remove its background first with the Background Remover, then watermark the result.
Compress After Watermarking
Since the output is always PNG, run the watermarked result through the Image Compressor afterward if the file needs to be smaller.
Best For
- Customizable text watermark with position, font size, color, and opacity controls - text only, there's no logo or image watermark option.
- Five fixed placement options: the four corners plus center - there's no diagonal, rotated, or tiled placement.
- Runs entirely in your browser using the Canvas API - your photos never leave your device, and the output is a full-resolution PNG.

Common Mistakes
Problem
Looking for a logo or image watermark option
Solution
This tool only supports a text watermark - there's no way to upload a second image, like a logo, to use as the mark.
Problem
Expecting a diagonal or rotated watermark
Solution
The watermark text is always drawn horizontally - there's no rotation or diagonal placement option, only the four corners and center.
Problem
Expecting a tiled or repeated watermark pattern
Solution
Only a single watermark instance is placed per image - there's no option to repeat it as a tiled pattern across the whole photo, which is the hardest placement to crop out.
Problem
Choosing a corner position for maximum protection
Solution
Corner watermarks are the easiest to remove by cropping. For stronger deterrence, place the watermark over the center of the subject instead.
Problem
Expecting the download to keep the original filename
Solution
The downloaded file is always named watermarked.png, regardless of what your uploaded file was called.
Tips & Best Practices
Center placement deters cropping better than a corner
A corner watermark can be cropped out in seconds. Placing it over the main subject at a moderate opacity is harder to remove without damaging the image.
Balance opacity with visibility
Higher opacity (60-100%) protects better but is more visually intrusive; lower opacity (20-40%) is subtler but easier to remove or ignore. Pick based on how much deterrence you need versus how much you want to preserve the image's look.
Use a text color that contrasts with your image
Since the font is fixed to bold sans-serif, choose a text color that stands out clearly against your image so the watermark stays legible.
Compress after watermarking if size matters
The output is always a full-resolution PNG - run it through the Image Compressor afterward if you need a smaller file.
Limitations
Text watermarks only
There's no logo or image watermark option - only typed text can be used as the mark.
No diagonal, rotated, or tiled placement
The watermark is placed horizontally at one of five fixed positions - the four corners or center. There's no rotation and no repeating tiled pattern, which is the strongest anti-crop placement.
One fixed font style
Watermark text always renders in bold sans-serif - there's no font-family selector, only an adjustable size.
Output is always PNG with a fixed filename
The result downloads as watermarked.png regardless of the source format or filename.
One image at a time
This page watermarks a single image per run - there's no batch or bulk watermarking option.
Comparisons
Corner Placement vs Center Placement
Where you place the watermark trades off visibility against how easily it can be cropped out.
| Corner (4 options) | Center | |
|---|---|---|
| Visual intrusion | Lower - tucked out of the way of the main subject | Higher - sits over the photo's focal point |
| Resistance to cropping | Low - can be cropped out in seconds | High - removing it damages the subject itself |
| Best for | Light branding on social media posts | Portfolio and product images where deterrence matters more |
Which should you use?
Use a corner for light, unobtrusive branding. Use Center when you actually want to deter reuse - it's harder to crop out without damaging the image.
FAQs
The most common question is whether watermarks can be removed. Visible watermarks on images can be removed by determined parties using image editing software. A more effective placement is the center of the main subject area rather than a corner - corners are easy to crop out. This tool doesn't offer a tiled, repeating pattern - the strongest anti-crop option - only a single mark at one of five positions, so the realistic goal here is deterrence and attribution, not absolute protection.
Can I control the watermark opacity?
Yes. An opacity slider lets you choose from a subtle watermark to a fully opaque one.
What positions can the watermark appear at?
You can place the watermark at the center, or any of the four corners of the image.
