The PDF Compressor API optimizes a PDF document to reduce its size. This PDF optimization is ideal when you are constrained by file size limitations without losing much on file quality.
Web API engines work in any programming language: PHP, Javascript, C#, .NET and ASP.NET, Java, Visual Basic, and many others.
The PDF Compressor API can optimize PDF files of any size. It works perfectly well with documents that contain images and text. All the documents are encrypted during transmission. To learn more about PDF.co Security, please read this article https://pdf.co/security
PDF Compressor API Benefits
Reduce Large Files
The Web API can automatically reduce a PDF file size. When working with large files, it is always considered a best practice to use async:true to avoid job interruption.
Maintain File Quality
The Web API can reduce a PDF file size without sacrificing the quality. Maintaining the balance between smaller file sizes and good quality is our highest priority. The PDF output of our PDF Compressor API works well with our other APIs.
Web API Supports Multiple Languages
PDF.co platform can be used by software developers from programming languages such as PHP, Javascript, .NET and ASP.NET, C#, Java, Visual Basic, and many others. Find source code samples in our API documentation.
Business Automation Platforms Integrations
If you are not a developer, you can also easily automate your PDF operations via popular business automation platforms: Zapier, Make, Airtable, Salesforce, Google Apps Script, and 300+ more.
