Frequently Asked Questions
What file formats are supported for conversion to PDF?
ConvertAPI supports almost all document format conversions to PDF, including MS Office (Word, Excel, PowerPoint), images (JPG, PNG, TIFF), ebooks, emails, drawings, AutoCAD, OpenOffice, iWorks, WEB & HTML, and more.
How does the OpenAPI schema help developers?
It enables dynamic converter integration, fetching converters and their parameters in real-time, on demand. It also ensures you always stay up to date and can accommodate all of our latest features, without manual updates or patching.
Can I generate dynamic PDF and inject custom values?
Absolutely! You can either use an HTML or DOCX template, and get your PDF with custom values in a single API call. The HTML to PDF and Web to PDF endpoints use browser-style rendering to preserve layout, CSS, and fonts accurately.
Can I extract data from PDFs?
You can use OCR and table extraction tools to convert content into text and CSV for easy processing. In addition to this, you can extract structured data using AI as well as retrieve images or form data from PDF.
Is document security supported?
Yes, you can redact, protect and flatten PDFs to meet compliance and privacy requirements. You can also convert it to PDF/UA to ensure accessibility or PDF/A, for long-term storage and compliance.
Can I watermark documents?
Text, image, and overlay watermark tools let you add brand identity or status stamps to your output files. Dynamic watermarks, like page numbers, dates, or PDF meta data can be added using predefined variables.
