PDF Merger

You can merge up to 50 PDF files in a single operation. For larger batches, consider splitting them into smaller groups. The tool processes files locally in your browser, so performance depends on your device's memory and processing power.

File size limits depend on your browser's memory capacity. Generally, you can process PDFs up to several hundred MB each. For very large files, consider compressing them first or processing smaller batches for optimal performance.

Merged PDF size depends on the original file sizes and compression. Images, fonts, and other embedded content can increase file size. The merged PDF maintains the quality and content of all original files.

Yes! Use the arrow buttons (↑↓) next to each file to reorder them before merging. The files will be merged in the order they appear in the list. You can also remove individual files using the trash icon.

Enter a password in the 'Password Protection' field before merging. The merged PDF will be encrypted with this password. Remember to save the password securely as it cannot be recovered if forgotten.

Absolutely! All PDF processing happens locally in your browser. Your files never leave your device or get uploaded to our servers. This ensures complete privacy and security for your documents.

Yes, click the 'Preview' button to view the merged PDF in your browser before downloading. This helps ensure the merge was successful and the pages are in the correct order.

Currently, our tool cannot merge password-protected PDFs. You'll need to remove the password protection from those PDFs first using a PDF editor, then merge them with our tool.
