You can now merge PDF documents automatically, to save many person-hours, and increase productivity. That is why we created an API to merge PDF files. Our code to merge PDF files is easy to use, and you can even integrate it into your in-house document management software.

Key Benefits of Using Our PDF File Merger API

Merge Large Files

You can merge large files easily in a matter of seconds. Most end-user PDF merging API will do it much slower, if you open two or more large PDF files, and try to merge them. Our API allows you to select large files and merge them automatically.

Choose Pages to Merge

Our API tool allows you to select the individual pages or a range of pages you want to be included in the merged PDF. You can also choose to merge entire PDF documents. Overall, that gives you greater flexibility on how you merge your PDFs.

Encryption

Privacy has become a big legal issue, and there are laws that require those handling protected private data, to encrypt it, when transmitting or storing it. Our merger API allows you to encrypt the merged output file.

To encrypt the output file, set “encrypt” as “true”. In that regard, our PDF Merger API helps you to comply with privacy laws. It also protects your business from lawsuits and government fines.

Asynchronously Merge Large PDF Files

The API’s code to merge PDF files can run asynchronously, to avoid timeouts. Users can merge documents in the background, and download them without having to refresh their browsers.

You can enable the “async” mode. the “async” input parameter should be set to “true”. We recommend you do that for large or multiple files. You can then use “/job/check” to check the final status of the background process. Once complete, it will return the status as “success”.

Steps to Execute Background Jobs and Asynchronous Modes

Step 1: Request URL

Use “file/upload/get-presigned-url” to get a “presignedUrl” and “url”. You will use “presignedUrl” to upload your file, and “url” to access the uploaded file.

Step 2: Upload URL

Use “PUT” to upload files to “presignedUrl”, and “url” to access the uploaded file.

Step 3: Call API Method

You can now call the API method with the input set as “url”, and “async” set to “true”, for the API method to return an output URL or URLs immediately.

The API method will also return a unique “jobId” that identifies the merging job you initiated.

Step 4: Check Job Status

Use /job/check API method with jobId param to check the execution status of your job you initiated.

Step 5: Download Merged File

Once the merging process is completed, the “/job/check API method with jobId param” will return “status” param as “success”. Download your merged files using the output URL/s in “Step 3”.
