Whether they want to highlight text, add notes, draw, or use any of the many annotation types supported by the PDF spec, our Annotations component will give your app the tools they need. Forms: By supporting the most commonly used standard, PDF AcroForms, your users can view, fill out, and submit forms with ease. Our Forms component gives your users the ability to save a filled-out PDF form or enter information that can be accessed and submitted to your server. Digital Signatures: As an extension of Forms, with Digital Signatures a user can sign documents using a personal certificate so your app can instantly verify the identity of the user. Indexed Full-Text Search: Our text extraction engine is one of the fastest in the industry and can deal with almost any PDF document, language, and encoding type. Indexing and search work across both document content and annotations. The SQLite-based full-text search delivers near-instant results, even for thousands of documents.
