Merge to PDF API

Merge nearly any input format into a single PDF. Upload hundreds of files at once — we’ll convert what’s needed and combine everything into one PDF.

Everything you need to merge files into one PDF

A reliable merge pipeline with automatic conversion, async processing, and storage integrations — built for production workloads.

Merge PDFs

Combine PDFs, documents, spreadsheets, presentations, and images into a single PDF — no need to pre-convert anything.

Convert any format to PDF

You can throw any format at us and we will handle it! CloudConvert automatically converts any document or image format before merging it into a single PDF file.

Async or Sync

By default, files convert asynchronously with webhook notifications on completion. Need instant results? Use our synchronous API for on-the-fly conversion.

Storage Integration

Fetch input files directly from your object storage and write output files back seamlessly. Integrated with S3, Azure, Google Cloud, and more.

Custom Workflows

Use Jobs to chain multiple operations in a single API call — convert to multiple formats, add watermarks, and generate thumbnails all at once.
