Cloudmersive PDF API
Pleasanton, California, United States
What it is
Cloudmersive PDF API lets businesses and developers process, create and manage PDF documents. It converts Word, Excel and PowerPoint files, including DOC, XLS and PPT formats, to PDF, and can render HTML or URLs into documents such as invoices and reports. For existing PDFs, it supports copying, merging, splitting, deleting, rotating and reordering pages, as well as creating or modifying annotations. The API can fill digital form fields and extract information from forms. It can also manage permissions, restrict printing or content extraction, and password-protect and encrypt PDFs. Deep-learning OCR extracts content from scanned PDFs. Cloudmersive lists SDKs and samples for more than 20 platforms and programming languages, and deployment options include public cloud, managed instance, private cloud, PaaS and government cloud. The API is available through API and self-hosted platforms. Cloudmersive says its stateless APIs do not retain payload data after a transaction. A free evaluation tier provides 600 calls per month, one call per second and a 3.5 MB maximum file size. Paid plans start at $19.99/mo.
