How it works
- Drop one or more PDF files into the upload area — they appear as a unified page grid ordered by upload sequence.
- Reorder, remove pages, or add more files — drag pages to change their position, select individual pages to exclude, or use the range fields to remove a block of pages in one step.
- Choose a compression level and click Export merged PDF — the file is generated entirely in your browser and downloaded to your device. Nothing is uploaded or stored anywhere.
When to use this tool
- Combining multiple scanned documents into a single PDF for submission to a government agency, employer, or university.
- Merging separately exported chapters or sections of a report before sending the final version to a client.
- Removing blank, duplicate, or confidential pages from a document before sharing it externally — pages never leave your device at any point.
- Reordering pages from multiple PDFs into a specific sequence, such as assembling a portfolio or inserting an appendix into an existing document.
- Consolidating multiple PDFs exported from the Markdown to PDF converter into one final file. You can then generate a QR code linking to a hosted version of the merged document.
Frequently asked questions
Are my PDF files sent to a server when I merge them?
No. Your PDF files are never sent to any server. All merging, page reordering, and compression runs entirely using JavaScript in your browser tab — nothing leaves your device. No account is required, and no data is transmitted to autotomate servers.
Can I add more PDFs after the first upload?
Yes. You can add more files at any point and the tool treats all uploaded PDFs as a single merged document. Drag to reorder pages or add files in any order — the final sequence is determined by the page grid before export.
Can I remove specific pages before exporting?
Yes. Select individual pages in the preview grid to exclude them, or use the range fields to remove a consecutive block of pages from X to Y in one step. The remaining pages are merged in the order shown.
Does the export support compression?
Yes. Choose from low, medium, or high compression before exporting. Higher compression reduces file size but may slightly reduce image quality inside the PDF. Low compression produces larger files with maximum fidelity.
Is this PDF merge tool free to use?
Yes. Merging, reordering, removing pages, and downloading the result is always free with no usage limits. No account, credit card, or sign-up is required at any point.
