Spotsaas Editor’s POV

ConvertAPI converts between 200+ file formats with reliable uptime and fast processing speeds. Before shortlisting, verify that your required format pairs are supported—the platform covers common conversions (PDF, image, document, video) but may lack niche formats. Test the API response time with your typical file sizes during a demo, as performance varies by ...Read more

"Convert API is a powerful REST API that helped us easily convert all our documents from word to PDF"

What do you like best about ConvertAPI? In the beginning, we tried to build our own conversion service, but it required a lot of investment and time. So we decided to leave these development & server management tasks for ConvertAPI and focus on what's more important for us. We like that this API is so easy to set up, and it is very reliable even if our usage grew massively over time.

PDF processing? ConvertAPI!

When looking for a service to handle all our automated PDF processing, we found out ConvertAPI to be the best service for us: - The product does everything it promises and we are in control of what is happening ($) - The clients (lib / sdks) are clean and very usable, we got tests running in minutes - The customer support is super reactive and helpful, even when we were on the free plan We looked for alternatives but they were either less responsive, less efficient / practical or simply ...

Superb product. Amazing support.

I was looking for a way for my customers to let them add a watermark on their PDFs automatically, and on each pages. I first tried to develop this feature "in-house" but it was not performing well and then I found ConvertAPI! Not only their product is amazing and works well but their support guys are always here to reply any question I have. Thanks for building this product!
