Frequently asked questions

How easy is it to integrate the Go SDK?

Whether you’re running monolithic apps or microservices, you can integrate it quickly by importing the library, setting your credentials, and invoking straightforward conversion methods. Its compatibility with standard Go tooling and package management ensures a smooth setup process.

Can I handle multiple conversions in parallel?

Yes. Taking advantage of ConvertAPI's concurrency model, you can process conversions concurrently with goroutines, significantly boosting throughput for large workloads. This makes it easier to scale your document processing and reduce overall execution time.

Are there specialized operations like redaction or OCR available?

Absolutely. In addition to standard conversions, the Go SDK supports advanced features such as redacting sensitive information and running OCR on scanned documents. These capabilities help consolidate various document workflows under one cohesive toolset.

How does the library perform with large documents?

The Go SDK is built for efficiency and robustness. It can handle big files and high volumes of conversions without sacrificing speed. You can also configure memory usage and file streaming options, ensuring consistent performance even under heavy loads.

Is it possible to chain multiple operations together?

Yes. You can create conversion workflows that apply a series of transformations to the same document. For example, you might convert a DOCX to PDF, apply protection, then compress the output—all within a single, orchestrated process.

Where can I find code examples and advanced configurations?

Our GitHub repository and official documentation include code samples and best practices for a range of use cases. These resources help you quickly experiment, learn, and refine your approach as you tailor the SDK to your project’s unique needs.
