PDF Merge / Split

Handles both directions of the same problem: combining several PDFs into one document, or breaking one PDF apart into separate files by page range. Reorder pages by dragging, preview each page as a thumbnail before committing, and export without needing desktop PDF software.

Why local processing matters here: merging and splitting PDFs is often done on contracts, tax documents, medical records, or anything else assembled into a single file for submission — exactly the kind of document where routing it through an unfamiliar server first, just to rearrange pages, is a real and avoidable exposure.

How to use it

  1. Upload one or more PDFs.
  2. To merge: drag files into your desired order, then combine into one document.
  3. To split: select a single PDF, view its page thumbnails, and choose a split point or specific page ranges to extract.
  4. Preview the resulting document(s) before export.
  5. Download the merged file, or the set of split files.

Common situations this solves

  • Combining several scanned pages into one PDF before submitting an application
  • Merging a cover letter and resume into a single document for a job application
  • Splitting a large multi-chapter PDF into individual chapter files
  • Pulling just a few pages out of a longer report to share separately
  • Assembling multiple signed pages, sent back individually, into one final document

FAQ

Can I reorder pages, not just merge whole files in upload order?

Yes — once files are uploaded, every page shows as a draggable thumbnail, so you can reorder individual pages, not just whole documents, before merging.

Does merging or splitting reduce file quality?

No, this is a structural operation on the document’s pages, not a re-encoding of the content — page content stays exactly as it was in the source files.

Can I split a PDF into more than two pieces?

Yes, define as many split points or page ranges as needed, and each becomes its own downloadable file.

What if I only need to remove one page, not split the whole document?

Splitting with a defined page range that excludes the unwanted page achieves the same result — export just the ranges you want to keep.

Is there a file size or page count limit?

No hard limit is enforced by the tool itself, though very large documents will naturally take a little longer to process since everything runs in your browser rather than on a server queue.

Can I merge PDFs with password protection?

No — remove the password first using PDF password protect / remove, since a locked PDF can’t be read and combined without that step. Locked pdfs will be skipped.
