Add watermark to image

A watermark is a visible mark added to an image — usually text, a logo, or a stamp — that identifies the creator, marks the image as a draft, or declares copyright. Watermarks are everywhere in photography, design, and stock imagery for good reason: they discourage unauthorized use.

Most online watermarking tools have either limited customization (only one position, one font, no opacity control) or require uploading your images. Our watermark tool will offer full positioning, font, color, and opacity control — and run entirely in your browser.

When you'll need this

Watermarking is useful when:

• You're a photographer. Add your name or studio logo to portfolio images.
• You sell stock images. Watermark previews before sale.
• You're sharing draft work. "DRAFT" or "WIP" overlay before final approval.
• You're protecting visual content. Make stolen images traceable back to you.
• You're running a business. Brand product photos with your company logo.
• You need confidentiality marks. "CONFIDENTIAL" overlay on internal documents.

Features will include: text or image watermark, custom position (9-point grid plus free-drag), opacity slider, rotation, font and color picker, and batch processing to hundreds of files in one go.

Private by design

Like everything else on pictoolkit, this tool will process your images entirely in your browser. No upload, no server-side processing, no temporary storage. Your files stay on your device.

While we finish this one, you can use any of our live tools — compress, convert, resize, HEIC to JPG, and our full format conversion suite are all available now.
