What Our Customers Are Saying:
PDF.co saved 2 to 3 hrs of manual labor weekly
I’ve been struggling with PDF documents (reading text from PDF documents and searching for a text inside), we use a lot of different ones, and it’s always been difficult to find one API and that can do everything we need at an affordable price. Well, I’ve just stumbled across PDF.co (PDF.co Document Parser and PDF text search), what a difference it’s made! I’m sure most of you know it, but if you don’t and you want to manipulate PDFs – check it out. I’m doing stuff automatically that I wasn’t able to do manually with Adobe Acrobat. I wish I’d found it earlier.

Automated 10 monthly hours of work
I used PDF.co’s API and Zapier integration for filling and flattening a PDF form as well as combining all the reports into one PDF. Before my integration, my clients were spending upwards of 10 hours per month putting reports together and sending to their clients. Now, that process is all entirely automated!

PDF.co reduced the processing time by more than 90%
PDF.co was used to determine the structure of each document, to extract each document’s field names, and to have those mapped to different database values. Using PDF.co reduced the time to fill documents by more than 90%.

Finally found PDF.co and am very happy now!
The employee saves around 22 hours a month. The modified document contains no errors anymore. The delivery department got the modified document in 15-30 min right after the supplier’s inquiry instead of 2-6 hours as it was before.

Saved dozens of work hours
PDF.co makes the general handling and processing of PDF documents easier – which is highly useful for a number of automated processes. Using PDF.co + Zapier to help manage the preparation of documents for filing claims has saved the client dozens of work hours and associated costs per week – and allowed them to scale the number of clients they can support.

PDF.co saves development expenses
The previous solution was fully custom coded via PHP and hosted on wordpress. This made any minor change to the data and/or PDF files a major hassle to update. WIth PDF.co we are able to make changes a few times a year very easily. This will save the client in development expenses down the line.

PDF Merge 2 Endpoint Sample & Demo
As mentioned above, there are 2 PDF Merger endpoints.
Because of the difference in file support, we will show different source code samples for each endpoint.
To demonstrate the /v1/pdf/merge2 endpoint, we will use these five (5) sample documents with different file formats. There’s a PDF file, a Word document, a Spreadsheet, a JPG, and a PNG.

PDF Merge Endpoint Sample & Demo
The /v1/pdf/merge has the same function as PDF Merge 2 except that the file support for this endpoint is exclusively in PDF format. If all of your source files are in PDF format, we recommend that you use this endpoint, otherwise, the /v1/pdf/merge2 endpoint would work best for you.
To demonstrate /v1/pdf/merge, we will use these two (2) PDF files and merge them into a single file.
