PureWatermark: Photo Protect

PureWatermark is a clean, simple, privacy-minded watermark app for creators, photographers, online sellers, designers, social media publishers, and anyone who needs to mark image ownership or source information. The workflow is direct: choose photos, select or edit a template, generate watermarked images, and save them to your album.

Add visible tiled text watermarks for author names, store names, account IDs, dates, copyright notices, or custom notes. Adjust the text style, size, spacing, opacity, angle, and color. Save common styles as templates, then reuse them for batch processing or camera watermarking.

PureWatermark also supports frequency-domain text watermarks. Embed short Chinese or English text inside an image as a hidden ownership mark, source note, copyright note, or private identifier. Hidden text does not appear as a normal overlay and can be read later inside PureWatermark. Standard mode is easy to use, while custom key mode supports more private scenarios.

All image processing happens locally on your device. Photos do not need to be uploaded to a server. PureWatermark focuses on watermark creation, batch processing, hidden marking, and a local privacy-friendly workflow. Hidden watermarks are intended as auxiliary marks, not legal-grade copyright evidence, and recovery is not guaranteed after heavy compression, severe cropping, or complex edits.
