Law firms can watermark confidential PDFs and images with 'DRAFT' or 'CONFIDENTIAL' to prevent unauthorized sharing. The tile mode ensures full coverage, while auto_adjust adapts to dark or light backgrounds.
Graphic designers and photographers can apply watermarks to JPG and PNG images before sending previews to clients. The adjustable opacity and font size allow branding without ruining the visual experience.
Corporations can batch watermark internal memos, reports, and presentations with 'Internal Use Only' to control information leakage. The tool supports multiple file formats and works across Windows, macOS, and Linux.
Journal editors and reviewers can mark submitted PDFs with 'Under Review' to prevent premature distribution. The center mode places a single watermark cleanly, and the opacity can be lowered for readability.
Government agencies can classify sensitive information by applying 'TOP SECRET' watermarks on documents and images. The tile mode ensures the watermark is virtually impossible to remove without damaging the content.
Offer free watermarking with a maximum file count per day (e.g., 10 files) and a paid tier for unlimited batch processing. Revenue comes from monthly subscriptions for professionals who handle many files.
Sell perpetual licenses to organizations for embedding the watermarking skill into their internal workflow. Provide customization options like custom fonts or corporate logo integration as add-ons.
Provide the watermarking functionality as an API endpoint for developers to integrate into their own apps (e.g., document management systems). Charge per transaction or via monthly API plans.
💬 Integration Tip
To integrate into a workflow, call the process_files function with a list of file paths; ensure pypdf, reportlab, and Pillow are installed. Add semantic triggers to automatically set mode to 'tile' when users mention '防伪' or '铺满'.
