PDF Merge / Split
Merge multiple PDFs into one, or extract a specified page range (merge / split).
Overview
- Offers a "Merge" mode that combines multiple PDF files into one, and a "Split / Extract" mode that extracts a specified page range from a single PDF.
- In merge mode, the pages of each PDF are concatenated in the order the files were selected.
- In split/extract mode, you specify page numbers or ranges separated by commas (e.g. "1-3,5,8-9") to extract only those pages into a new PDF.
Usage
- Select "Merge" or "Split / Extract" as the mode.
- In merge mode, select multiple PDFs to combine and click "Merge".
- In split/extract mode, select a single PDF, enter the page range to extract (e.g. 1-3,5,8-9), and click "Extract". Save the result via "Download".
Example
Input
report-1.pdf + report-2.pdf (merge mode)
Output
merged.pdf (all pages combined)
Use Cases
- Combining multiple document PDFs into a single file to submit or share
- Extracting only the pages you need from a large scanned PDF
- Reordering PDF pages by specifying the page range in a custom order (e.g. 3,1,2)
FAQ
Is the uploaded PDF sent to a server?
No. All processing happens entirely in your browser (client-side); the PDF is never sent to a server.
Can password-protected PDFs be processed?
No. A password-protected (encrypted) PDF will fail to load. Please remove the protection beforehand.
Can I split one PDF into multiple files at once?
Currently, only extracting one specified page range into a single new PDF is supported. Splitting into multiple files at once is not supported.
Notes
- Uploaded PDFs must be 20MB or smaller per file.
- Password-protected (encrypted) PDFs cannot be loaded.
- Page ranges are 1-indexed (for example, the first page is "1").
