What You Can Control With Merge Action
With the Merge action, you can control how multiple PDF files are combined into a single output and how their page order is preserved.
- Selecting multiple PDF files to merge
- Defining the merge order based on input sequence
- Preserving original page order from each PDF
- Combining documents into one single output PDF
- Handling multi-file inputs within one request
- Preparing merged PDFs for further processing actions
PDF Endpoint Capabilities
The PDF endpoint provides a set of production-ready document operations designed for automation, document workflows, and backend processing.
merge
Combines multiple PDF files into a single document while preserving page order, structure, and layout for unified document delivery.
compress
Reduces the file size of PDF documents using safe compression techniques that preserve page structure, readability, and document integrity.
split
Splits a PDF into separate files by page range, enabling flexible document segmentation for storage, processing, or delivery needs.
extract
Extracts selected pages from a PDF document into a new file, enabling page-level reuse, redistribution, or focused document workflows.
to-images
Converts PDF pages into image files, enabling visual previews, thumbnails, or downstream image-based processing workflows.
watermark
Applies text or image watermarks to PDF pages with controlled placement and repetition, supporting branding and document ownership needs.
delete-pages
Removes selected pages from a PDF document, allowing precise document trimming without modifying remaining content.
reorder
Changes the order of pages within a PDF document, allowing logical restructuring without altering page content or formatting.
rotate
Rotates PDF pages by fixed angles to correct orientation issues and normalize document presentation.
encrypt
Applies password-based encryption to PDF documents to restrict access and protect sensitive content during storage or delivery.
decrypt
Removes password protection from encrypted PDFs when permitted, enabling downstream processing and document access.
flatten
Flattens interactive PDF elements into static content, ensuring consistent rendering and preventing form or annotation modification.
extract-images
Extracts embedded images from PDF documents while preserving original resolution and format, enabling asset reuse or downstream processing.
metadata
Extracts PDF metadata such as author, creator, and creation information and returns it as structured data, without modifying the document content.
Why Developers Use the PDF Endpoint
Document-Safe Processing
The PDF endpoint provides controlled document transformations designed to preserve structure and readability, making it suitable for production workflows.
Automation-Ready Design
All actions are built for backend automation, scheduled jobs, and batch processing where manual intervention is not possible.
Comprehensive Document Control
From compression and splitting to encryption and watermarking, the endpoint covers common document lifecycle operations in one place.
Batch-Friendly Operations
Supports multi-file workflows such as merging multiple PDFs, as well as actions that generate multiple outputs in a single request, improving efficiency for document pipelines.
Secure Output Handling
Processed documents are returned through structured responses with controlled output URLs for safe system integration.
Predictable, Documented Behavior
Each action follows explicit rules and parameters, allowing developers to build reliable integrations with minimal surprises.
Production-Grade Reliability
Limits, timeouts, and execution behavior are enforced consistently to support long-running and high-volume document workflows.
Use Cases Powered By PDF Endpoint
Document Compression Pipelines
Automatically reduce PDF file size by compressing documents, removing unnecessary pages, and flattening forms before storage or delivery, ensuring faster transfers and lower storage costs.
Report & Invoice Processing
Generate clean, standardized reports and invoices by merging PDFs, reordering or extracting pages, flattening form fields, and applying watermarks for branding or approval workflows.
Document Archiving Systems
Prepare PDFs for long-term storage by restructuring page order, removing sensitive pages, extracting metadata for indexing, and encrypting files to meet compliance and retention requirements.
Secure File Distribution
Protect PDFs before sharing by applying encryption, removing unwanted pages, adding watermarks, and controlling document structure to ensure files are safe for external distribution.
Automated Backend Jobs
Integrate the PDF endpoint into background jobs to process documents at scale—splitting large PDFs, converting pages to images, extracting embedded assets, or restructuring files without manual intervention.
Frequently Asked Questions
Pdf Endpoint FAQ
1. What is the PDF endpoint used for?
The PDF endpoint lets you work directly with PDF files through the Davix H2I API. It is designed for document-processing tasks such as merging PDFs, converting PDF pages into images, compressing PDFs, extracting images, adding watermarks, rotating pages, updating metadata, reordering pages, deleting pages, extracting page ranges, flattening PDFs, encrypting, decrypting, and splitting files.
2. What PDF actions are supported?
The public PDF endpoint supports these actions:
merge,to-images,compress,extract-images,watermark,rotate,metadata,reorder,delete-pages,extract,flatten,encrypt,decrypt, andsplit.3. Can I use the PDF endpoint for automated document workflows?
Yes. Davix H2I is designed to support automated document workflows, including systems that need to generate, modify, transform, or route PDF files as part of larger applications and automation pipelines.
4. Do I need to build my own PDF-processing infrastructure?
No. Davix H2I provides PDF-processing capabilities as a backend service, so you can add PDF operations to your workflows without building and maintaining the underlying infrastructure yourself.
5. How do I connect to the PDF endpoint?
You connect to the PDF endpoint through the public API using your API key. The
/v1/pdfroute is part of the public Davix H2I API surface and is designed for direct integration into applications, backend services, and workflows.6. What files can I upload to the PDF endpoint?
The PDF endpoint accepts PDF uploads as its main input. It also supports one optional image upload for watermark-related workflows when needed.
7. Can I merge multiple PDF files into one document?
Yes. The
mergeaction is supported for combining PDF files into a single output document.8. Can I convert PDF pages into images?
Yes. The
to-imagesaction is supported for turning PDF pages into image outputs. The endpoint also includes options related to page selection, output format, quality, and density for these workflows.9. Can I extract images from a PDF file?
Yes. The
extract-imagesaction is supported for retrieving embedded images from PDF documents.10. Can I add a watermark to a PDF?
Yes. The PDF endpoint supports watermarking. It includes support for text-based watermark settings and can also work with an uploaded image for watermark-related processing.
11. Can I rotate, reorder, delete, or extract specific pages?
Yes. The PDF endpoint supports
rotate,reorder,delete-pages, andextract, which makes it suitable for document-editing workflows that need page-level control.12. Can I split a PDF into separate files?
Yes. The
splitaction is supported for dividing a PDF into multiple output files based on page ranges.13. Can I update or clean PDF metadata?
Yes. The
metadataaction is supported. The public PDF examples also show support for metadata fields such as title, author, subject, keywords, creator, and producer, along with an option to clean metadata before applying updates.14. Can I protect or unlock PDF files?
Yes. The PDF endpoint supports both
encryptanddecrypt, which allows it to be used in workflows that need password protection or controlled document access.15. What does a successful PDF response return?
Successful PDF requests return either a single output URL or a results array, depending on the action. Output files are returned through the public PDF output path under
/pdf/*.16. Can I use the PDF endpoint in apps, websites, and automation tools?
Yes. Davix H2I is designed to work across custom applications, backend services, websites, and automation environments, which makes the PDF endpoint suitable for many different implementation styles.
