Secure Your PDFs: Effortlessly Add Custom Text and Image Watermarks Using Our Powerful API

In today's digital-first world, documents are constantly shared, circulated, and stored. For businesses, developers, and entrepreneurs, ensuring the authenticity, integrity, and branding of PDF files is paramount. Whether you're protecting sensitive information, asserting copyright, or simply reinforcing your brand identity, watermarking stands as an essential line of defense. Manually adding watermarks can be tedious and prone to errors, especially when dealing with high volumes. This is where the TompisAPIs' PDF Watermark API revolutionizes your workflow, offering a powerful, flexible, and scalable solution to effortlessly embed custom text or image watermarks into your PDF documents.

Our API is engineered for simplicity and robust performance, allowing you to add both text and image watermarks with unparalleled ease. The primary endpoint /api/pdf-toolkit/pdf-watermark/ facilitates single-file operations, while the /api/pdf-toolkit/pdf-watermark/batch/ endpoint is designed for efficient mass processing. Here’s a glimpse into its core capabilities:

• Flexible Watermark Types: Choose between dynamic watermark_text for messages like 'CONFIDENTIAL' or 'DRAFT', or upload a logo_file (supporting PNG, JPG, GIF, SVG) to brand your documents. You must provide at least one of these.
• Precise Placement Control: Define the position of your watermark with options like center, top-left, top-right, bottom-left, bottom-right, or use custom coordinates with x_offset and y_offset for pixel-perfect placement.
• Visual Customization: Adjust the watermark's appearance with parameters for rotation (from -360 to 360 degrees), scale (0.1 to 5.0), and opacity (0 to 1) to ensure it's visible yet unobtrusive.

Beyond basic placement, our PDF Watermark API offers a rich set of parameters for truly bespoke watermarking solutions:

• Text Watermark Enhancements: Control the aesthetics of your text watermarks with font_family (Helvetica, Arial, Times, Courier), font_size, font_weight (normal, bold), and text_color (hex codes like #000000).
• Image Watermark Sizing: For logo watermarks, precisely control the logo_size in pixels while maintaining aspect ratio.
• Intelligent Page Selection: Apply watermarks to all pages by default, or target specific pages using odd, even, first, last, or a comma/space-separated list of page numbers (e.g., '1,3-5'). You can also explicitly skip_first_page or skip_last_page for covers or appendices.
• Repeat Patterns for Comprehensive Coverage: For maximum impact, enable repeat_pattern to tile your watermark across the entire page, defining the spacing with repeat_spacing_x and repeat_spacing_y in pixels. This ensures your mark is visible regardless of how the document is viewed or printed.

Integrating the PDF Watermark API into your existing applications is straightforward. It operates via standard HTTP POST requests, accepting your PDF file along with the desired watermark parameters. The API provides versatile output options to fit your workflow:

• Direct PDF Download (pdf): The default and most common option, providing the watermarked PDF directly for download.
• Base64 Encoded JSON (base64): Ideal for web applications, receiving the processed PDF as a base64 string within a JSON object for easy embedding or manipulation. This response also includes valuable metadata like filename, size, and processing_time.
• Comprehensive ZIP Archive (zip): For a complete package, this option returns a ZIP file containing the watermarked PDF, the original PDF, your logo image (if provided), and a metadata.json file detailing the process and parameters. This is particularly useful for auditing or archival purposes.

The API is designed for minimal latency and includes robust error handling with clear error codes, ensuring a smooth developer experience. Whether you're building a document management system, an e-commerce platform requiring watermarked invoices, or a content delivery service, our API provides the flexibility you need.

The applications of the PDF Watermark API are diverse and impactful:

• Enhanced Document Security: Deter unauthorized sharing and distribution by visibly marking documents with 'CONFIDENTIAL' or 'DO NOT COPY' watermarks.
• Brand Reinforcement: Automatically apply your company logo or branding to all outgoing reports, contracts, or marketing materials, strengthening brand recall and professionalism.
• Copyright Protection: Safeguard your intellectual property by embedding copyright notices or ownership information directly into your PDF content.
• Workflow Automation: Integrate the API into automated document generation pipelines for invoices, certificates, or legal documents, ensuring every PDF adheres to branding and security policies without manual intervention.
• Draft and Status Indication: Clearly mark documents as 'DRAFT', 'PREVIEW', or 'ARCHIVED' to manage document lifecycle and prevent confusion.

By leveraging our API, businesses can achieve greater control over their digital assets, streamline document processing, and significantly enhance their security posture, all while saving valuable time and resources.
