Secure Your Documents: Easily Add Text or Image Watermarks to Your PDFs with Our API

In today's digital landscape, document security and brand integrity are paramount. Whether you're a SaaS provider handling sensitive client data, an entrepreneur protecting intellectual property, or a developer building document management solutions, the need to mark your PDFs with watermarks is undeniable. Watermarking serves as a powerful deterrent against unauthorized distribution, signifies document status (e.g., 'Draft', 'Confidential'), and reinforces brand identity. Manual watermarking can be tedious and prone to errors, especially when dealing with large volumes of documents. This is where the TompisAPIs PDF Watermark API steps in, offering a robust, automated, and highly customizable solution for all your watermarking needs.

Forget about clunky software or manual processes. Our API empowers you to integrate seamless watermarking capabilities directly into your applications, ensuring efficiency, consistency, and top-tier document security.

The TompisAPIs PDF Watermark API is designed for simplicity and power, allowing you to easily embed both text and image watermarks into your PDF documents. Our API provides developers and businesses with the flexibility required to meet diverse requirements. The core of its functionality revolves around a straightforward POST request to the /api/pdf-toolkit/pdf-watermark/ endpoint.

Key Features:

• Text Watermarks: Add custom text like 'Confidential', 'Draft', or 'Do Not Copy' to your documents.
• Image Watermarks: Embed your company logo or any other image (PNG, JPG, GIF, SVG) to brand your PDFs effectively.
• Precise Positioning: Choose from predefined positions such as center, top-left, top-right, bottom-left, bottom-right, or define exact coordinates with x_offset and y_offset for custom placement.
• Rotation Control: Rotate your watermark by any angle between -360 and 360 degrees for unique visual effects or specific document requirements.
• Adjustable Scale & Opacity: Control the size of your watermark with a scale multiplier (0.1–5.0) and its visibility with opacity (0-1), ensuring it complements without obscuring content.

Beyond basic placement, our PDF Watermark API offers a deep level of customization, ensuring your watermarks look exactly how you envision them. This flexibility is crucial for maintaining brand guidelines and conveying the right message.

For Text Watermarks:

• Font Selection: Choose from standard fonts like Helvetica, Arial, Times, or Courier.
• Font Size & Weight: Adjust font_size and font_weight (normal, bold) to match your document's aesthetic.
• Color Control: Specify text color using hex codes (e.g., #FF0000 for red) with the text_color parameter.

For Image Watermarks:

• Logo Sizing: Set the exact logo_size in pixels, with the aspect ratio intelligently preserved for crisp, clear branding.

These parameters allow you to create watermarks that are not just functional but also seamlessly integrated into your document design, enhancing professionalism and effectiveness.

The TompisAPIs PDF Watermark API goes beyond individual document watermarking, offering advanced features for comprehensive document management:

• Granular Page Selection: Apply watermarks to all pages, odd, even, first, last, or a specific range/list of pages (e.g., 1,3-5).
• Skip First/Last Page: Easily omit watermarks on the first or last page with skip_first_page and skip_last_page boolean parameters.
• Repeat Patterns: For maximum coverage, use repeat_pattern: true to tile your watermark across the page, defining the spacing with repeat_spacing_x and repeat_spacing_y. This is ideal for sensitive documents requiring strong visual protection.

For organizations dealing with high volumes of documents, our dedicated Batch Endpoint at /api/pdf-toolkit/pdf-watermark/batch/ is a game-changer. It allows you to watermark multiple PDF files in a single request, receiving a ZIP archive containing all the watermarked PDFs and a summary. This feature is indispensable for:

"Processing bulk invoices, legal documents, or academic papers with consistent watermarking policies, saving immense time and resources."

The versatility of the TompisAPIs PDF Watermark API makes it suitable for a wide range of applications:

• Document Security: Mark confidential reports, contracts, or internal memos with 'Confidential' watermarks to prevent unauthorized sharing.
• Branding & Marketing: Embed your company logo on all outgoing documents, from marketing materials to official letters, enhancing brand recall.
• Copyright Protection: Protect creative works, photographs, or digital publications by adding visible copyright notices.
• Draft & Review Cycles: Clearly mark documents as 'Draft' or 'For Review Only' during collaborative processes.
• Educational Institutions: Watermark academic papers or certificates with institutional logos or 'Official Transcript' status.

Integrating the API is straightforward. You upload your PDF file(s) and specify your watermark parameters via a POST request. The API offers flexible response types:

• pdf (default): Direct download of the watermarked PDF.
• base64: The watermarked PDF as a base64 encoded string within a JSON response, perfect for web applications.
• zip: A ZIP file containing the watermarked PDF, the original PDF, and if provided, the logo file, plus metadata. Ideal for archiving and detailed processing.

With clear error handling and a robust infrastructure, you can quickly implement secure watermarking into your existing workflows, be it for a web service, a desktop application, or an automated backend process.
