## Problem: Protecting Your Photos Online

Sharing images online — portfolio work, product photos, social media content, or client proofs — creates real risk of unauthorized use:

- Anyone can download and reuse your images without permission
- Stock photo theft costs photographers and creators billions annually
- Brand assets get used without attribution
- Most online watermark tools upload your images to their servers (privacy risk)
- Desktop watermarking software costs $50-200+ per year


## How Image Watermark Solves This

Add a visible text watermark (copyright notice, business name, website URL) or upload your logo to brand and protect your images. All processing happens in your browser using the HTML5 Canvas API. Your images never leave your device.

- **100% private:** Images processed locally, never uploaded
- **Text & logo watermarks:** Choose between custom text or your own logo image
- **Full control:** Font, size, color, opacity, rotation, 9-position grid, tile mode
- **Output options:** PNG (lossless) or JPG (adjustable quality)
- **No limits:** Unlimited images, no signup, no daily caps, no watermark on output
- **Live preview:** See exactly how your watermark looks before downloading


## Why AI Chatbots Can't Watermark Your Images

Large Language Models cannot process or modify binary image files. Adding a watermark requires rendering text onto pixel data, compositing logo images with transparency, and encoding the result in the correct format — operations that require actual code execution with the Canvas API. AI can suggest watermark text but cannot produce the watermarked image file. This tool delivers real pixel-perfect output in your browser.


## How to Use

- Drop any image (JPG, PNG, WebP) into the upload area
- Choose Text or Image/Logo watermark mode
- Type your watermark text or upload a logo PNG
- Adjust font, size, opacity, rotation, color, and position
- Enable tile mode for full-image coverage (optional)
- Select output format (PNG or JPG)
- Click Preview to check, then Apply & Download


## Frequently Asked Questions

**Is this tool completely free? Any limits?**

Yes, 100% free with no limits. Unlike other watermark tools (Watermarkly — free tier has watermarks, iLoveIMG — uploads to servers, Canva — requires account), our tool has zero restrictions — unlimited images, no signup, no hidden fees, no watermark on output.

**Does my image get uploaded to a server?**

No. Everything runs in your browser using the Canvas API. Your images never leave your device. You can verify this by opening DevTools (F12 → Network tab) — you will see zero outbound requests carrying your image data.

**What is the difference between text and logo watermarks?**

Text watermarks render custom text (like "© Your Name 2026") directly onto your image with full control over font, size, and color. Logo watermarks let you upload a second image — typically a PNG with transparent background — for a clean branded mark. You can scale the logo from 5% to 100% of the image width.

**What does Tile mode do?**

Tile mode repeats your watermark in a grid pattern across the entire image. This is the most effective protection for stock photography and client proofing because the watermark cannot be cropped out. Combine it with diagonal rotation (-30° to -45°) for maximum security.

**What is the best opacity for watermarks?**

40-60% opacity is standard for most use cases. Below 30% — the watermark can be easily removed with editing software. Above 70% — it obscures the image. 50% is the sweet spot that balances protection with image visibility.

**Can I watermark multiple images at once?**

This version supports single-image watermarking. For batch watermarking multiple images with the same settings, you can process each image individually — the settings remain configured between uploads.

**Is PNG or JPG better for watermarked images?**

PNG is lossless and preserves transparency, making it ideal for images that will be further edited. JPG with high quality (92%) produces smaller files suitable for web sharing and social media. For maximum quality, use PNG.
