Combine PDF documents into one file

When information is spread across several PDF documents, combining them can make the final file easier to share, store or submit. Docelora's Combine PDF tool is designed to help you bring related documents together in the order you choose.

You can add multiple PDF files as well as JPG or PNG images. Before creating the final document, arrange the files so that each document or image appears where you expect it to.

Tip: Check the file order before starting the combine operation. The order of the items in the workspace determines their sequence in the resulting document.

How to combine PDF files

Add your files

Choose the PDF, JPG or PNG files you want to bring together, or drag them into the upload area.

Arrange the order

Drag the file cards into the sequence you want them to appear in the combined document.

Combine the files

When the order is correct, select Combine PDF to send the files for processing.

Why combine PDF files?

Combining related documents can make a collection of separate files easier to manage. Instead of sending several attachments individually, you can create a single document when a single PDF is more convenient.

Common examples

Reports and supporting documents Bring a main report and supporting PDFs together into one organised document.

Scanned paperwork Place scanned PDF pages or image files into a single document sequence.

Applications and submissions Combine forms and supporting documents when a single PDF is requested.

Project documents Keep related project material together rather than managing many separate files.

Supported files and practical limits

The Combine PDF interface accepts PDF documents and common image formats including JPG, JPEG and PNG.

File-size, file-count, processing-time and resource limits should be enforced by the production processing service. Browser-side checks are provided to improve the user experience, but they should never be treated as the security boundary.

Before uploading

Make sure the files are the documents you intend to combine.
Check the order of the files before starting the operation.
Use supported PDF, JPG, JPEG or PNG files.
Very large or unusually complex documents may require additional processing time.

Combine PDFs and images in one workflow

A useful document workflow does not always involve PDFs alone. For example, you may have a PDF report followed by a photograph or scanned page stored as a PNG or JPG. Combining these items can help keep the final sequence together.

Docelora therefore treats supported images as part of the same ordering workflow. Add the files, arrange them, review the sequence and then start the combine operation.

Frequently asked questions

The interface is designed for multiple files. The final production limit will be enforced by the processing service based on file size, page count and available processing resources.

Yes. The tool interface supports PDF, JPG, JPEG and PNG files so that supported images can be included in the same document sequence.

Yes. Drag the file cards to change their order. The sequence shown in the workspace is intended to represent the sequence used for combining.

This page provides the upload and ordering interface. Production PDF creation is intended to be handled by Docelora's secure processing service rather than pretending that a result was created when no processing service is connected.

The processing service should validate uploaded files and return a clear error when a file is unsupported, damaged, encrypted or otherwise unsuitable for the requested operation.

Protected PDFs may require the appropriate password or authorisation before they can be processed. Do not upload documents you are not authorised to access or process.
