Image Watermark

Watermarking images is standard practice for photographers, designers, content creators, and businesses who share visual work online. A watermark identifies ownership, deters unauthorized reuse, and ensures your brand is visible even when images are shared outside their original context. This tool adds both text watermarks (copyright notices, website URLs, brand names) and image watermarks (logos, stamps) to photos directly on your device, with full control over position, opacity, size, and placement, without uploading anything to a server.

How to use

1. Open your image. Drop a JPG, PNG, or WebP file onto the tool or click to browse. The image loads in the preview canvas where you'll see watermark placement in real time.
2. Choose watermark type. Select Text to add a typed watermark (your name, URL, or copyright notice). Select Image to overlay a logo or stamp file, upload the watermark image (transparent PNG works best for image watermarks).
3. Adjust appearance. For text watermarks: set the font, size, color, and opacity. For image watermarks: set the size and opacity. Drag the watermark in the preview to position it exactly where you want it, corners, center, diagonal, or tiled.
4. Download the watermarked image. Click Download to save the result. The output is a JPG at high quality with the watermark permanently composited onto the image.

Tips for best results

• Use semi-transparent watermarks. A watermark at 50–70% opacity is visible enough to assert ownership while still allowing the underlying image to be seen clearly. Fully opaque watermarks at 100% look heavy and unprofessional; watermarks at 20% or below are too easy to miss.
• Place watermarks away from edges. Edge placement is easier to crop out. Center or mid-image diagonal placement makes removal more difficult while keeping the watermark visible. For important protection, a repeating tiled pattern is the hardest to remove.
• Use a transparent PNG logo for image watermarks. A PNG with transparency lets only the logo itself appear over the image, without a rectangular white or colored background box. If your logo has a solid background, remove it in a design tool like Canva, Figma, or Photoshop before uploading it as a watermark.
• Resize images before watermarking. If you're preparing images for a specific platform or size, use the image resizer first. Watermark placement at the target size ensures the text or logo is the right proportion for the final output dimensions.

Why use PixMidas

• 100% private. Watermark compositing uses the browser's Canvas API. Your photos are never uploaded to any server, especially important for unreleased work, personal photos, and confidential client images.
• Text and image watermarks. Both modes are supported, type a copyright notice or URL as text, or overlay your logo or stamp as a PNG image watermark.
• No account needed. Free and instant. Watermark compositing runs locally on your device.

Frequently asked questions

What is the best watermark opacity to use?

For professional use, 40–60% opacity strikes the right balance, clearly visible when someone looks for it, but not so dominant that it ruins the image for legitimate viewing. For copyright protection on sensitive or commercially valuable images, 60–75% opacity with a diagonal or centered placement makes removal more difficult. For subtle branding on social media, 20–35% is common to keep the watermark unobtrusive while still identifying the source.

Can watermarks be removed?

Any digital watermark can be removed given sufficient effort, AI-based inpainting tools can now remove many watermarks in seconds. A well-placed, semi-transparent watermark serves primarily as a deterrent and a clear statement of ownership that holds up legally, not as an impenetrable barrier. For maximum protection of valuable work, combine watermarking with low-resolution distribution and digital rights management (DRM) if needed for commercial assets.

What is the best position for a watermark?

The most secure position for deterrence is the center or a diagonal overlay across the entire image, these positions cannot be removed by simple cropping. For photos where you want the image to remain aesthetically pleasing, bottom-right is the conventional placement. Avoid placing watermarks in corners where a simple crop removes them entirely.

Can I watermark multiple images at once?

The tool processes one image at a time since watermark placement may need adjustment for each image. For batch watermarking many images with identical settings, image editing applications like Photoshop (Batch/Actions) or free alternatives like GIMP with Script-Fu can apply the same watermark to hundreds of images automatically.

What format is the output?

The watermarked image is saved as a JPG at high quality. The Canvas API composites the watermark directly onto the pixel data and exports a JPG. If you need a PNG output (for example, to preserve a transparent background), the image converter can convert the JPG output to PNG.

Can I use a logo as a watermark?

Yes. Use the Image watermark type and add your logo file. For the best result, your logo should be a transparent PNG, the transparent areas allow the underlying photo to show through, so only the logo shape itself appears over the image. If your logo is on a white background, remove it in a design tool like Canva, Figma, or Photoshop to create a transparent PNG before uploading it here.
