Add Text or Image to PDF Using Our API

PDF.co platform helps to easily automate adding text, images, signatures to existing PDF files or PDF templates.

When you need to add your signature, company logo, graph, pictures, or stamp a status such as PAID to a document, the PDF Editor Web API’s Add Image (or Stamp) to PDF do it all.

Here are the things that the Web API can do:

• Resize and add the image anywhere in the PDF.
• Specify the page, pages, and page range you want to add the image so there’s no need to split the PDF.
• Make the image clickable. You can redirect it to any URL.
• Works with PDFs that require HTTP auth username and password.
• Supports image formats such as JPG, PNG, BMP, and TIFF.

The PDF output files generated by the Web API are set to expire after an hour by default. The temporary URLs are also stored in random names for added security. You can configure your workflow to delete the files after use if you prefer to remove them right away. To learn more about PDF.co Security, please check out our Security page here.

PDF Editor Web API Benefits

Ease of Use

The PDF Editor Web API is very straightforward to use. You only need to fill your data in the parameters, run it and instantaneously get the result. We have templates, sample code snippets in various programming languages, and tutorials to guide you in using the Web API.

Add Images to PDF

You can add JPG, PNG images on top of the PDF file. You can also add semi-transparent PNG and GIF files and use base64 encoded (Datauri) URLs with embedded images.

Add Image Anywhere

You can set the coordinates where you want to add your image or stamp to the document. Our PDF Viewer tool can help you find the coordinates. You can access it in the Helper Tools inside your PDF.co account.

Large File Support

The Web API supports asynchronous file processing. This allows the engine to do the job in the background. This will return a Job ID and check the job status later on.

You can use PDF files located in your Dropbox, Google Drive and you can also use built-in PDF.co Files Storage to store PDF files, images, signatures for re-use with the PDF.co platform.
