What is the PDF Merger and Splitter?

This tool combines several PDF documents into one and extracts selected pages from a document into a new file. Everything runs in your browser, so the documents are never uploaded.

Merging and splitting are structural operations on a PDF. Merging appends the pages of one document to another and produces a single file; splitting selects a subset of pages and writes them out as a new document. Neither re-encodes page content, so quality is unaffected.

These are among the most common document tasks, assembling scanned pages into one file, combining an application's supporting documents, or pulling a single relevant section out of a long report.

Because PDFs so often contain sensitive material, where this processing happens matters. Most online merge tools upload your documents to their servers. Doing the work in the browser means an invoice or a signed contract never leaves your machine.

How to use the PDF Merger and Splitter

  1. Upload your PDFs. Select one file to split, or several to merge. Files are read locally.
  2. Arrange the order. For merging, set the sequence in which documents should be combined, this determines page order in the result.
  3. Or select pages to extract. For splitting, specify the page numbers or ranges you want in the new document.
  4. Download the result. The merged or extracted document is generated and downloaded. Source files are unchanged.

Worked examples

Merging several documents

Pages are concatenated in the order you specify, and numbering runs continuously through the result.

Input
cover-letter.pdf     (1 page)
resume.pdf           (2 pages)
certificates.pdf     (3 pages)
Output
application.pdf  (6 pages)

Pages 1        cover letter
Pages 2-3      resume
Pages 4-6      certificates

Extracting a page range

Range syntax lets you pull out non-contiguous sections in one operation.

Input
Source: report.pdf (48 pages)
Select: 1, 5-9, 22
Output
extract.pdf (7 pages)

Page 1, pages 5 through 9, and page 22,
in the order specified.

Common use cases

  • Assembling job applications. Combining a cover letter, CV, and supporting documents into the single file most portals require.
  • Consolidating scanned pages. Scanners frequently produce one file per page, which need combining into a single document.
  • Extracting a relevant section. Pulling a few pages from a long report to share without sending the whole document.
  • Removing unwanted pages. Selecting only the pages you want is an effective way to drop blank or irrelevant ones.
  • Reordering a document. Splitting and remerging in a different sequence rearranges pages.

Features and limitations

  • Merges any number of PDFs in an order you control.
  • Extracts individual pages or ranges into a new document.
  • Runs entirely in your browser with no upload.
  • Page content is copied rather than re-encoded, so text, images, and quality are preserved exactly.
  • Source files are never modified, the result is a new download.

Frequently asked questions

Are my documents uploaded?

No. Everything happens in your browser. This is the main reason to prefer a local tool for PDFs, which so often contain contracts, financial details, or identity documents.

Does merging reduce quality?

No. Pages are copied as they are rather than re-encoded, so text stays sharp and images are unchanged. The merged file's size is roughly the sum of its inputs.

Is there a limit on file size or count?

The practical limit is your browser's available memory, since documents are held in memory during processing. Very large documents may be slow, and combining a great many files at once can exhaust memory.

Can I merge password-protected PDFs?

Encrypted documents generally need to be unlocked first, because their page content cannot be read while protection is in place.

Are bookmarks and form fields preserved?

Basic page content, text, and images are preserved reliably. Interactive features such as form fields, annotations, and bookmarks may not survive merging, so check the result if your document depends on them.

How do I reorder pages within one document?

Extract the pages in the order you want, or split into sections and merge them in the new sequence.

All processing happens locally in your browser, your data never leaves your device.
