What is PDF Conversion SDK?
Enhance your application with PDF functionalities by utilizing just two API calls: Open, Edit, and View PDF. With a simple configuration file and these API calls, you can enable your app to swiftly import, view, modify, and open PDF documents within a single day. The SDK is designed to bridge format discrepancies, offering features such as cropping, color management, fills, and font adjustments. It facilitates the conversion of any PDF versions, including the ISO Standard PDF 2.0, allowing for versatility with any PDF file or print-ready document as an input. The conversion process is streamlined, ensuring a smooth experience without any intermediary steps or loss in quality, and it eliminates the need for a printer driver. Compatible with Windows, MacOS, and Linux, the PDF Conversion SDK also supports .NET and comes with sample code for your reference. Additionally, it effectively removes unnecessary data and compresses files, leading to enhanced performance during web and application browsing, making it an efficient choice for developers. By adopting this technology, you can significantly improve the user experience when handling PDF files.
What is AiDO for Developers?
AiDO for Developers helps product and engineering teams add document features to their software without building an in-house PDF team. Embed PDF viewing, editing, conversion, OCR, e-signatures and AI data extraction through one SDK and API from a single vendor, so your developers can focus on your core product.
The problem: document features often turn into a 3-6 month detour, several vendors for OCR, conversion and signing, and engineers maintaining PDF edge cases for years. AiDO for Developers replaces that with one integration that Avanquest maintains, backed by 20+ years of production use.
Four products, each available separately:
PDF API: cloud REST API to convert, merge, split, compress, OCR, watermark, protect and sign documents, plus AI data extraction.
PDF SDK: native SDK for Windows and Linux (C++ and C#/.NET).
PDF Web SDK: white-label PDF experiences in your web app, with theming, annotation, redaction, signing and forms.
WebApp: ready-to-use web component for viewing, annotating and searching PDFs.
Why teams choose it:
One vendor for the whole document stack
Cloud or on-premise deployment, with documents staying in your environment when you use the SDKs
Transparent, published pricing with all features in every plan
Pricing (USD, billed annually): Cloud API: Free (500 documents, 30 days), Starter $6,000/year (~10,000 docs/month), Scale $36,000/year (~100,000 docs/month), Enterprise custom. PDF SDK: Starter $5,000/year, Scale $25,000/year, Enterprise custom.
