Frequently Asked Questions

Everything you need to know about watermarking images

How does the Image Watermark tool work?
Upload your images and configure your watermark in the workspace. You can add text watermarks with full typography control or upload a logo/image watermark. Each element can be positioned, rotated, and styled independently. See changes in real time with the interactive canvas preview. When ready, process all images at once and download individually or as a ZIP archive. All processing happens entirely in your browser — your images never leave your device.
What image formats are supported?
You can upload images in JPG, JPEG, PNG, WEBP, AVIF, and BMP formats. Output formats include PNG (recommended for transparency), JPEG, WEBP, and AVIF. PNG is best for watermarks with transparency. JPEG is great for photographs but doesn't support transparency.
Can I add multiple text watermarks?
Yes! You can add unlimited text watermarks, each with its own content, font, size, color, opacity, rotation, shadow, outline, and background settings. Each text block is independently positioned on the canvas — drag to place it anywhere, or use the position presets for quick alignment.
Can I use my logo as a watermark?
Yes! Upload your logo (PNG with transparency recommended) and customize its size, opacity, rotation, corner radius, shadow, and blend mode. The logo is rendered on top of your image at the position you choose. Logo and text watermarks can be used together.
What is watermark tiling?
Tiling repeats your watermark across the image in a pattern. Choose from Single (one watermark), Repeat (horizontal and vertical repetition), Diagonal (diagonal pattern), or Grid (full grid). Adjust spacing between tiles and per-tile rotation for custom patterns. Tiling is great for full-coverage protection.
What position options are available?
Choose from 9 preset positions (Top Left, Top Center, Top Right, Center Left, Center, Center Right, Bottom Left, Bottom Center, Bottom Right) or drag any watermark element freely on the canvas. Adjust margins from image edges and enable snap-to-guides for precise alignment.
Can I watermark multiple images at once?
Yes! Upload multiple images and configure your watermark settings once. All images will be watermarked with the same settings. You can preview the watermark on any image in the batch list before processing. Download results individually or as a single ZIP archive.
Is my privacy protected?
Absolutely. All image watermarking happens entirely in your browser using the Canvas API. Your images and logos are never uploaded, copied, or transmitted to any server. No third-party services, no analytics tracking the content of your images, no data leaving your device.
What is the maximum file size?
The tool supports images up to 100 MB in size and batches of up to 100 images. For very large images, processing may take a moment depending on your device. The interactive preview is optimized for smooth performance even at high resolutions.
How do I remove a watermark element?
Select the watermark element by clicking it on the canvas, then press the Delete key or click the trash icon in the element's settings panel. You can also toggle visibility to temporarily hide an element without deleting it.

Tips and best practices for image watermarking

What is Image Watermarking?

Watermarking is the process of overlaying a visible mark (text or logo) onto an image to assert ownership, protect copyright, or brand content. Effective watermarks balance visibility with aesthetics — they should be noticeable enough to deter unauthorized use but subtle enough to not distract from the image itself.

Text vs Logo Watermarks

Text watermarks are ideal for copyright notices, website URLs, or social media handles. They're flexible and can be styled to match your brand. Logo watermarks (like a company emblem) are best for brand recognition. Using both together provides the strongest protection — the text asserts ownership while the logo reinforces brand identity.

Watermark Position and Placement

The most common watermark positions are bottom-right, center, and top-left corners. Bottom-right is least intrusive as viewers' eyes naturally scan there last. For stronger protection, use a tiled pattern across the entire image. Always leave some margin from the edges to prevent easy cropping of your watermark.

Opacity and Visibility Balance

A watermark should be visible enough to deter theft but subtle enough to not ruin the image. Start with 50-70% opacity and adjust based on the image content. Dark images need lighter watermarks, while light images need darker ones. Adding shadow or outline helps the watermark stand out against the background regardless of the image content.
