Frequently Asked Questions

Is there a file size limit?

Since all processing happens in your browser, the main limitation is your device's memory. Most modern devices can handle PDFs up to 100MB total size. For very large files, we recommend merging them in smaller batches for optimal performance.

Can I merge password-protected PDFs?

Currently, our tool cannot process password-protected or encrypted PDF files. You'll need to remove the password protection first using the original software that created the PDF or our PDF Unlock tool.

Will my PDF formatting be preserved?

Yes, our tool maintains the original formatting, layout, and quality of your documents. Text remains searchable, images stay crisp, and hyperlinks continue to function in the merged PDF. However, some complex interactive elements might not transfer perfectly.

Is my data secure when using this tool?

Absolutely. Our PDF merger processes everything locally in your browser. Your files never leave your device or get uploaded to any server. This ensures complete privacy and security of your sensitive documents.

Can I merge different types of PDFs?

Yes, you can merge any type of PDF files, including scanned documents, digitally created PDFs, forms, and image-based PDFs. The tool will combine them while preserving their individual characteristics as much as possible.

Do I need to install any software?

No installation is required. Our PDF merger works entirely in your web browser. Simply visit the website, upload your files, and merge them without downloading or installing any additional software.
