Watermark Adder
A professional digital protection suite for photographers and content creators. Upload up to 50 images and apply fully customizable watermarks - choose between custom text with 8 professional fonts or your own logo (PNG/SVG). Place the watermark precisely with a 3x3 position grid and fine-tune with X/Y offset sliders. Enable diagonal tiling for full-image coverage with adjustable density. Control opacity, scale, rotation, fill and stroke colours, and canvas blend modes (Normal, Screen, Overlay, Multiply, and more). For invisible protection, toggle Stealth Metadata to embed your copyright or owner ID directly into EXIF fields (Copyright, ImageDescription, UserComment) using piexifjs. Preview every change in real-time on a live canvas, toggle between original and watermarked views, and zoom in to inspect details. Process the entire batch and download individual files or one-click export everything as a ZIP. All processing runs 100% in your browser - your images never leave your device.

Can I protect my photos with both a logo and text?
Imagine you're a hard-working creator wanting to brand every single image you post - our tool is exactly what you need. You can upload a high-quality logo or use a sleek text watermark with professional fonts, and adjust the position, transparency, and size for an 'expensive' branded look.
What is the 'Stealth Metadata' feature for?
Ever worried someone might just crop out your watermark and use your photo? Our 'Stealth' mode lets you embed your name or copyright directly into the hidden data fields of the JPEG itself, providing proof of ownership even if the visible watermark is gone.
How can I block someone from cloning out my watermark?
Our 'Tiled Watermarking' mode is perfect for that. It repeats your watermark diagonally across the entire image at a density you pick, making it effectively impossible for anyone to crop or clone it out without ruining the photo's detail.
