Merge PDF files for free

PDF files are among the most popular document formats – whether for applications, contracts, invoices, certificates, or private documents. However, documents often exist in several individual PDF files and need to be merged into a single file before sending or archiving.

With Louvion's free PDF merger, you can do this directly in your browser. Simply upload your PDF files, set the desired order, and receive a new merged PDF file within a few seconds. No installation or registration is required.

A special advantage: The processing takes place directly on your device. Your documents are not uploaded to or stored on our servers. This keeps usage fast, convenient, and data protection-friendly.

What are the advantages of our PDF merger?

Our goal was to develop a tool that simply works and is pleasant to use. That's why the tool focuses on the most important functions, without unnecessary distractions or complicated settings.

Key benefits include:

  • Free to use
  • No registration required
  • No installation necessary
  • Processing directly in the browser
  • Privacy-friendly
  • PDF order freely adjustable
  • Preview of the first PDF page
  • Display of page count and file size
  • Fast download of the finished PDF
  • No watermarks

This makes the tool suitable for both private and professional use.

Which documents is the tool suitable for?

Merging multiple PDF files makes sense in many situations. Often, several documents need to be sent together or saved as a single file.

Typical use cases include:

  • Merging application documents
  • Combining resumes and cover letters
  • Adding certificates
  • Collecting invoices
  • Compiling contracts
  • Bundling reports and presentations
  • Organizing study materials
  • Preparing forms for authorities
  • Reducing PDF attachments for emails
  • Archiving private documents

Especially with applications, a single PDF file makes it easier for HR managers to process and at the same time creates a professional impression.

Your data stays on your device

Data protection plays a particularly important role when it comes to personal documents. That's why our PDF merger processes all files directly in the browser.

This means:

  • Your PDFs are not uploaded to Louvion servers.
  • There is no permanent storage of your documents.
  • After downloading, the files remain exclusively on your own device.

Especially for sensitive documents such as applications, contracts, or certificates, this local processing offers an additional level of security.

Easily change the order of PDFs by drag & drop

The order of the pages often determines how clear a document will appear later. That's why you can easily reorder your PDF files by drag & drop.

After uploading, all documents are displayed clearly. Simply drag the files to the desired position. When merging, the tool will use exactly this order.

For example, you can place your cover letter first, then your resume, and then all certificates – all without re-uploading.

Preview before merging

To help you keep track, the tool displays a preview of the first page of each PDF file.

In addition, important information is displayed directly:

  • File name
  • File size
  • Number of pages
  • Total number of PDFs
  • Total size of all files
  • Total number of pages

This way, you can see if all documents have been completely and correctly sorted even before merging.

Why merge PDF files?

Several individual PDFs can quickly become unmanageable – especially when they are to be sent or archived together.

A single PDF file offers numerous advantages:

Several individual PDFs
A combined PDF
  • Sending multiple attachments
  • Higher risk of confusion
  • More administrative effort
  • Unclear shipping process
  • Send only one file
  • Clear order
  • Easy to archive
  • Professional impression

Especially for applications or business documents, a merged PDF appears much more structured and professional.

Combine PDF files online for free

Many programs for editing PDF files are paid or require installation. Our tool takes a different approach.

You can merge your PDFs directly online – for free and without an account.

This saves you time and allows you to use the tool regardless of the operating system. Whether Windows, macOS, Linux, Android, or iPhone – as long as a modern browser is available, the PDF merger can be used without problems.
