Full Control Watermarking: Add Custom Text or Image Watermarks to Your PDFs Easily

In today's digital-first world, safeguarding your intellectual property and maintaining brand consistency across documents is paramount. Whether you're a SaaS provider, a burgeoning startup, or an enterprise looking to streamline operations, the need for robust PDF management tools is undeniable. TompisAPIs introduces the PDF Watermark API, a powerful solution designed to give you unparalleled control over adding custom text or image watermarks to your PDF files. This comprehensive API goes beyond basic watermarking, offering an array of features that ensure your documents are not just protected, but also reflect your professional identity with precision.

Forget manual, time-consuming processes. Our API empowers developers and businesses to programmatically embed watermarks, making it an essential component for automated document generation, legal document processing, or simply enhancing the integrity of your digital assets. Let's dive into how this API can transform your PDF workflows.

The PDF Watermark API offers extensive customization options for text watermarks, ensuring your message is delivered exactly as intended. You can easily add dynamic text such as 'CONFIDENTIAL', 'DRAFT', or specific document IDs, tailored to fit any use case. Key features include:

• Custom Text Input: Simply provide the watermark_text parameter with your desired string.
• Font Control: Choose from popular fonts like Helvetica, Arial, Times, or Courier using the font_family parameter.
• Styling Options: Adjust font_size, set font_weight to normal or bold, and define the text_color using hex codes (e.g., #FF0000 for red).
• Positioning and Orientation: Pinpoint your watermark's placement with preset position options (center, top-left, bottom-right, etc.) or use precise x_offset and y_offset values for custom locations. Add flair with rotation, allowing any angle from -360 to 360 degrees.
• Transparency and Scale: Control the visibility of your watermark with the opacity parameter (0 for transparent to 1 for opaque) and resize it with the scale multiplier (0.1 to 5.0).

This level of detail ensures your text watermarks are not just present, but perfectly integrated into your document's aesthetic and purpose.

Beyond text, the PDF Watermark API allows you to embed custom logos and images, turning every PDF into a branded asset. This is invaluable for companies that rely on visual identity for recognition and trust. Upload your company logo, a copyright symbol, or any other image (PNG, JPG, GIF, SVG) using the logo_file parameter.

The API provides similar granular control for image watermarks as it does for text:

• Flexible Sizing: Define the logo_size in pixels, with the aspect ratio intelligently maintained.
• Strategic Placement: Utilize position, x_offset, and y_offset to ensure your logo sits perfectly on the page.
• Dynamic Effects: Apply rotation for angled effects and adjust opacity and scale to make your logo subtle or prominent, depending on your branding guidelines.

Whether it’s a faint brand mark in the background or a clear 'do not copy' stamp, the API makes it effortless to integrate visual watermarks effectively.

The PDF Watermark API stands out with its intelligent page selection and powerful batch processing capabilities, making it ideal for both individual document tasks and large-scale operations:

• Targeted Page Selection: Apply watermarks to all pages, odd or even pages, the first or last page, or specify a custom list or range of pages (e.g., 1,3-5) using the pages parameter. You can also skip_first_page or skip_last_page for added flexibility.
• Repeat Watermark Patterns: For enhanced security and brand visibility, enable repeat_pattern. Define the horizontal (repeat_spacing_x) and vertical (repeat_spacing_y) spacing in pixels to create a tiled watermark effect across your document pages.
• Efficient Batch Processing: For processing multiple PDFs simultaneously, the dedicated /api/pdf-toolkit/pdf-watermark/batch/ endpoint is a game-changer. Simply upload up to 10 PDF files, apply your desired watermark settings, and receive a ZIP file containing all watermarked PDFs and a summary. This feature is crucial for businesses handling high volumes of documents.

These advanced features ensure your watermarking strategy is both efficient and highly effective, adapting to the most complex document requirements.

Designed with developers in mind, the PDF Watermark API offers straightforward integration and versatile output options:

• POST Method & Clear Endpoints: Interact with the API using standard HTTP POST requests to /api/pdf-toolkit/pdf-watermark/ for single files or /api/pdf-toolkit/pdf-watermark/batch/ for multiple.
• Multiple Response Types: Choose how you receive your watermarked PDFs:
  • Direct PDF Download (pdf): Get the watermarked PDF file directly.
  • Base64 String (base64): Receive the PDF as a base64-encoded string within a JSON object, perfect for web applications or internal processing.
  • ZIP Archive (zip): Obtain a ZIP file containing the watermarked PDF, the original PDF (if applicable), and any provided logo files, along with metadata. This is especially useful for auditing or keeping records.
• Custom Filenames: Specify the filename parameter to control the name of your output PDF.
• Robust Error Handling: The API provides clear error_code and descriptive messages for easy debugging and robust application development.

Integrating this API into your existing applications, whether in Python, Node.js, or any other language, is made simple through its well-documented parameters and consistent response structure. It empowers you to build sophisticated PDF processing solutions with minimal effort.
