Watermark a whole batch of photos at once, privately
Protecting product photos, portfolio shots, or event pictures with a watermark usually means opening each image one at a time in an editing app — slow, and often means uploading your photos to yet another website. This tool does the opposite: upload up to 20 photos together, set your watermark once (a logo, or your business name as text), and every photo gets the exact same watermark applied instantly, entirely inside your browser.
Choose between a logo image watermark (a PNG with transparency works best) or a text watermark with a custom color, then fine-tune opacity, size relative to the photo width, and position — any of the four corners, dead center, or a repeating tiled pattern across the whole image, the same style stock photo sites use to make an image unusable without a proper license. The live preview updates instantly as you adjust each setting, and it's driven by the exact same code that generates your final photos — what you see in the preview is exactly what you'll get.
Built for a full batch without crashing your browser
Processing 20 full-resolution phone photos at once can easily overwhelm a browser tab if they're all held in memory simultaneously. This tool processes photos one at a time — decode, watermark, export, release, then move to the next — so memory use stays bounded even on a mid-range phone. Once processing finishes, download each watermarked photo individually or grab all of them at once as a single ZIP file.
Your photos never leave your device
Every step — reading your photos, drawing the watermark, and building the ZIP archive — runs entirely in your browser using the HTML canvas API and JavaScript. Nothing is ever uploaded to a server, which matters for unreleased product shots, client photos under a confidentiality agreement, or anything you're not ready to make public yet. Your watermark opacity, size, and position choices are also remembered in your browser for next time, so you don't have to re-tune them on every visit.
Once your photos are watermarked, a BizGo digital business page gives you a free, shareable gallery to publish them alongside your services, WhatsApp button, and Google review link — all in one place.
Frequently Asked Questions
