About Simple Watermark

Part of the GoodTool suite

Simple Watermark is a fast, privacy-first batch photo watermarking tool designed for photographers, creators, real estate agents, e-commerce sellers, and professionals who need to protect their digital images without uploading confidential assets to remote cloud servers.

Key Philosophy: Everything runs 100% locally inside your web browser. No server uploads, no logins, no paywalls, and no watermark of our own on your photos.

Why We Built It

Most online watermarking utilities force users to upload gigabytes of personal or commercial photos to an unknown server. This exposes creators to serious privacy risks, bandwidth slowdowns, and restrictive paywalls after only a handful of photos.

By utilizing modern Web APIs such as the Canvas API, OffscreenCanvas, and File System Access API, Simple Watermark processes hundreds of photos in parallel with zero server dependencies.
