What is WatermarkForge?
WatermarkForge is a free, browser-based watermark tool that lets you protect your images in seconds. Whether you're a photographer, content creator, blogger, or business owner — you can add a professional watermark to any photo without installing any software or creating an account.
Everything runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server — they stay completely private on your device throughout the entire process.
WatermarkForge supports text watermarks, logo/image watermarks, timestamp overlays, batch processing, and tile mode — all in a single free tool with no signup required.
How to Watermark Images Online
Adding a watermark to your photo takes under 30 seconds. Here's the step-by-step process:
Upload Your Photo
Drag and drop your image onto the upload zone, or click to browse. Supports PNG, JPG, WEBP, and GIF formats. You can upload multiple images at once for batch watermarking.
Choose Your Watermark Type
Select Text to add a custom text watermark — type your copyright notice, brand name, or any message. Choose a font family, style, size, color, and rotation angle. Switch to Image to upload your logo or signature as the watermark instead.
Adjust Opacity & Position
Use the opacity slider to control how visible your watermark appears — from a subtle 10% to a bold 100%. Choose from 9 placement positions using the grid, or enable Tile mode to repeat the watermark across the entire image.
Add a Timestamp
Enable the timestamp overlay to burn a date and time onto your image. Choose from multiple formats: datetime, date only, time only, ISO 8601, friendly format, or enter custom text. Control font size, color, opacity, and position independently from the main watermark.
Download Your Watermarked Image
Select your output format — PNG, JPEG, or WebP — and click Download. For multiple images, use the batch download feature to save all watermarked photos at once.

🖼 Use the Tool Above ↑Why Use an Online Watermark Tool?
Desktop software like Photoshop can add watermarks, but it's expensive, slow to open, and overkill for a quick job. An online watermark maker like WatermarkForge lets you protect images in seconds — directly in your browser, on any device, without downloading anything.
Tips for Effective Watermarking
- Use a transparent PNG logo — gives a cleaner, more professional look than a JPEG with a white background
- Set opacity to 20–40% — visible enough to deter theft, subtle enough not to ruin the image
- Position in a corner or center — corner watermarks are easier to crop out; center or tile mode is more secure
- Use Tile mode for extra protection — repeated watermarks across the image are nearly impossible to remove cleanly
- Match font to your brand — use the same font and color as your logo for a consistent visual identity
