Reliable and easy to integrate

We use ConvertAPI in our back-office to convert Excel files generated dynamically from many variables into PDF documents. The integration was straightforward, conversions are fast, and the output is clean and reliable. It saves us from handling the conversion manually and fits our workflow very well.

The only improvement I would suggest would be a smaller paid plan between the free tier and the first paid plan, with a lower quota and a price better suited to lighter usage.

ConvertAPI is very straightforward to implement and use, offering an impressive variety of file converters and a broad selection of integration platforms. The documentation is excellent, and the sandbox environment makes getting started even easier.

Support is on point!

So we have been using ConvertAPI for many years - honestly, the process from setup to coding is a breeze.
Recently, had an issue where the image converted to a PDF was not fitting into an A4 size but reaching out to support, within the next time of them validating my issue they rolled out a patch update.
We don't often have issues but when we do, they are on it.

Reliable Tool - Highly Recommended

I’m very satisfied with Convert API. Their service is reliable, efficient, and seamlessly integrates into my workflow and niche sites. The API’s robust functionality and excellent customer support make it a top choice for my conversion needs. I use Convert API for a variety of tasks, including document conversion and data processing, which helps streamline my business operations.

Initially, I had some concerns about the payment structure, but Tomas and Paulius from customer care quickly resolved the issue. Their prompt and helpful assistance reassured me of the company’s commitment to customer satisfaction.

Having tried other services, I chose Convert API for its superior performance and comprehensive features. The user-friendly interface and detailed documentation also make it easy to implement and use. I would highly recommend Convert API to anyone looking for a dependable and versatile conversion tool. Special thanks to Tomas and Paulius for their exceptional support!

Great, easy to use PDF conversion tool

We have been using Convert API in our company for over a year to merge pdf-files for digital invoicing in our ERP environment.
There was a seamless integration with our ERP-system and therefore the set-up and license activation was a piece of cake. The service works stable and so far without any issues.
It does what it has to do, no complaints!

We use ConvertApi to automatically extract compressed files through Zapier. I haven't found any other solution that can do what ConvertApi does. So far we've been liking this tool because it's easy to navigate and works well with Zapier. Highly recommended to check it out!
