How does the watermark tool work?

This tool uses your browser's built-in Canvas API to overlay text on your image with customizable size, color, opacity, and position. The entire process runs locally on your device — your images are never sent to any server.

Tips for Adding Watermarks

  • Set opacity between 30–50% for subtle branding — A watermark should protect your work without ruining the viewing experience. An opacity of 30–50% makes the watermark visible enough to deter theft while keeping the image enjoyable for legitimate viewers.
  • Use tiled mode for maximum protection — The tiled watermark option repeats your text or logo across the entire image in a diagonal grid pattern. This makes it virtually impossible to crop or clone out the watermark, providing the strongest protection for preview images.
  • Position strategically — Place single watermarks on important areas of the image that cannot be easily cropped out. Corners are convenient but easily removable. Center or slightly off-center positions over key content offer better protection.
  • Use white text with a dark shadow — White watermark text with subtle shadow or outline is visible on both light and dark image areas. Pure white or pure black text alone may disappear on matching backgrounds.
  • Keep watermark text short — Use your name, brand, website URL, or a simple copyright symbol (e.g., "© 2025 Your Name"). Long text clutters the image and looks unprofessional.
  • Match watermark size to image resolution — A watermark that looks good on a 1920px image may be too small on a 4000px image, or too large on an 800px thumbnail. Adjust the font size relative to the image dimensions.

When to Watermark Your Images

  • Protecting photography portfolios — Add watermarks to portfolio previews shared online to prevent unauthorized use of your photographs. Clients can view the composition and quality, while the watermark discourages downloading and reuse without a license.
  • Client proofing — Send watermarked proofs to clients for review before delivering the final, unwatermarked versions. This is standard practice in professional photography and ensures payment before delivering the high-resolution files.
  • Stock photography submissions — Many stock photography platforms display preview images with watermarks. Add your own before uploading to marketplaces or sharing samples with potential buyers.
  • Social media branding — Add a subtle watermark with your brand name or logo to images shared on social media. When images get reshared or go viral, viewers can always trace them back to you.
  • Protecting design mockups — Watermark design proposals, website mockups, and artwork drafts shared with clients for feedback. This protects your intellectual property during the approval process.

Frequently Asked Questions

Can the watermark be removed?
The watermark is permanently embedded into the exported image pixels. It cannot be easily removed, which makes it effective for protecting your work. Keep your original unwatermarked file safe.
What is the tiled option?
The tiled option repeats your watermark text diagonally across the entire image. This provides stronger protection since the watermark cannot be cropped out. It is commonly used for stock photos and proofs.
What output formats are available?
You can export your watermarked image as JPEG, PNG, or WebP. Choose the format that best suits your needs.
What opacity level should I use for my watermark?
For subtle branding, 20–30% opacity works well — the watermark is visible on close inspection but doesn't distract from the image. For stronger protection (client proofs, stock previews), use 40–60% opacity. Avoid going above 70% as it makes the image difficult to evaluate and looks unprofessional.
Where should I place my watermark?
For branding, the bottom-right corner is the standard position — it's visible but unobtrusive. For protection, center the watermark over the main subject so it can't be cropped out. For maximum security, use the tiled mode which covers the entire image with repeated watermarks.
Does adding a watermark protect my copyright?
A watermark serves as a visual deterrent and a notice of ownership, but it does not create or replace legal copyright protection. In most countries, copyright exists automatically when you create an original work. A watermark helps prove ownership and discourages unauthorized use, but for full legal protection, consider registering your work with your country's copyright office.
Can I watermark multiple images at once?
The watermark tool processes one image at a time, giving you full control over watermark placement and appearance for each photo. After downloading one watermarked image, you can quickly load the next. Your watermark settings (text, opacity, position, size) are preserved, making it fast to process a series of images.
