Use Cases
What people use Private PDF Merge & Split for:
- Combine documents in the right order
Merge several assignment or report PDFs into one file, in exactly the order you set — for example before submitting a thesis with its appendices.
- Reorder files with the keyboard
Drag a row, or use the up and down controls with the keyboard. The merged output always follows the displayed order, and screen readers announce each move.
- Extract a page range
Save only pages 3–5 of a long document as their own PDF, so you can share the slice without sending the whole file.
- Split several ranges at once
Enter ranges like 1-4, 10-12, 20 and get one correctly named file per range — or pack them all into a single ZIP.
- Keep a sensitive document local
Contracts, medical papers, or theses are processed on your device and never uploaded — verified by our network-level tests.
Frequently Asked Questions
- What exactly does this app do?
- It merges multiple PDF files into one PDF in the order you choose, and it extracts any page (or page range) you name into new PDF files. Both operations happen in your browser.
- Are my files uploaded anywhere?
- No. Everything is processed on your device. Your files, filenames, and generated PDFs are never sent to our servers or to any third party. (Standard site analytics may still load, as on all AppDoesIt pages.)
- Why does my merged PDF lose its digital signature or form fields?
- Rebuilding a PDF from its pages can drop digital signatures, interactive form fields, annotations, bookmarks, attachments, and metadata. This is a limitation of the format, not a bug — verify the output before signing or filing anything important.
- Can I work with a password-protected PDF?
- No. We can detect that a file is password-protected but we cannot (and will not) remove passwords. Open or unlock the file first, then merge or extract.
- Is there a file-size limit?
- There is no imposed quota — no account, email, or daily limit. The practical limit is your device's memory: very large or very numerous files may fail, in which case we tell you clearly and keep your originals.
How to use PDF Merge & Split
Getting started
- Add PDF files by clicking the drop zone or dragging and dropping them. Every file is read and checked on your device.
- Reorder the files with the up/down buttons or by dragging a row. The merge output always follows the displayed order.
- Merge: with 2 or more files selected, click "Merge PDFs" and download the result (merged.pdf).
- Extract pages: pick a source PDF, enter 1-based pages or ranges separated by commas (e.g. 1-2, 4, 9-12), and click "Extract". Each range becomes its own file; "All as ZIP" packs them together.
- Cancel stops the current job at any time. Reset clears the selection, ranges, results, and errors in one action.
Where do my files go?
Nowhere. Everything runs in your browser: files are processed on your device and are not sent to any server or third party. (Standard site analytics may still load, as on all AppDoesIt pages.)
About the output
Rebuilding a PDF from its pages can drop digital signatures, interactive form fields, annotations, bookmarks, attachments, and metadata. That is a format limitation, not a bug — verify the output before use. Password-protected files are detected but cannot be opened here.
