"Huge time savings thanks to ConvertAPI"
What do you like best about ConvertAPI? Implementing the API in our software was straightforward. Setting up the JSON request, calling the API, download the result. That was all to use ConvertAPI to convert files from PDF to JPG.

It works perfectly
Love ConvertAPI and the team there. It's super easy to use. The dev tools make it easy to get started and the team is super responsive. I haven't tried the other vendors out there. When I found the Convert site, saw their pricing and live demo I decided I didn't need to waste time looking at other options.

MyCumulus data to Pythagoras to JPG...
Just 60 lines of VBA code, namely setting up the JSON request, calling the API, and downloading the result, within the MyCumulus Pythagoras GIS-CAD macro was sufficient to automate the process of converting PDF to JPG files. Implementing the API was straightforward. The time saved for our customer is considerable. Previously, dozens of files had to be converted one by one for each project. Now the whole conversion process runs automatically. No hassle with screenshots, manual conversions, ...

"Easy API to use"
What do you like best about ConvertAPI? ConvertAPI has been a reliable service for converting even legacy Word Document files to PDF. ConvertAPI has also been helpful in re-exporting PDF files with unexpected password protection metadata when the document is already accessible. Their integration libraries make development more straightforward too.

Great API
Great API Their website gives specific clear instructions on how to do conversion from different formats. It is very useful for developers. Their website also allows you to use their API as well so we can try out the settings and see the results before we integrate it into our apps/programs. Tried ilovepdf's API but I find ConvertAPI has a better documentation. Definitely will recommend ConvertAPI to other people that might need this!
