Merge PDF

Merge multiple PDF files locally in your browser into one new PDF using a custom order.

Input

Private by design: your PDF files never leave your device.

Your PDFs are processed only in this browser and are not uploaded.
Merging creates a new PDF file. Existing digital signatures therefore remain not cryptographically valid.

Merge plan

Add at least two PDF files.

Good to know

The Merge PDF lets you merge multiple PDF files into one document directly in your browser. It is useful for document workflows, office work, archiving, delivery preparation, and technical checks when PDF files need to be prepared or converted quickly.

Typical searches for this page include merge PDF, combine PDFs, join PDF files, PDF merger, and multiple PDFs into one. Processing runs locally in the browser, so documents are not uploaded for processing. The file order determines the page order in the output; arrange PDFs deliberately before merging.

Typical use cases

Prepare documents for sending and archiving

Edit PDF files before email delivery, portal upload, internal archiving, or sharing with customers and colleagues.

Make PDFs usable in other formats

Convert content, pages, or parts into images, Office files, or structured working formats when a PDF cannot be processed directly.

Local editing of confidential documents

Use local processing for contracts, invoices, internal documents, or drafts that should not be transferred unnecessarily to external services.

Tips for better results

Keep the original file

Save the result under a new name and keep the original PDF until content, page order, quality, and file size have been checked.

Review before sharing

PDF structures, embedded fonts, images, passwords, and forms can behave differently depending on the file. Open important results before sending them.

How it works

    Review options

    Review page range, quality, output format, or security options for the desired result.

  3. 3

    Save the result

    Download the generated file and open it for review before sharing or archiving it.

Direct download

After local processing, the result is ready to download immediately.

Frequently asked questions

Are files uploaded when using the Merge PDF?

No. Processing runs locally in the browser. Files are not transferred to Xoricon or another server.

Is the original PDF preserved?

Yes. The tool creates a new output file. The selected original file on your device is not overwritten.

Why can PDF processing fail?

Possible causes include damaged files, strong encryption, unusual PDF structures, very large documents, or browser memory limits.
