Frequently Asked Questions

Are my PDF files uploaded to your servers?

No, absolutely not. All PDF processing happens directly in your browser using client-side JavaScript. Your files never leave your device, ensuring complete privacy and security.

What's the maximum file size I can merge?

Each individual PDF file can be up to 50MB, and you can merge up to 20 files at once. This accommodates most document merging needs while maintaining good performance.

Can I change the order of pages in the merged PDF?

Yes, you can change the order of entire PDF files by dragging and dropping them in the file list. The pages within each PDF will maintain their original order.

What happens if one of my PDF files is corrupted or invalid?

Invalid PDF files will be marked with an error icon and excluded from the merging process. You can remove them from the list or fix them before trying again.

Does the tool work on mobile devices?

Yes, the PDF Merger works on all modern browsers including mobile devices. However, for better performance with large files, we recommend using it on desktop or tablet devices.

Can I merge password-protected PDF files?

Currently, password-protected PDF files cannot be merged. You'll need to remove the password protection first using appropriate PDF tools before merging.

Is there a limit to how many pages the final PDF can have?

There's no strict page limit, but very large documents (thousands of pages) may take longer to process and could impact browser performance depending on your device's capabilities.
