Complete Guide to PDF Merging

Our PDF merge tool is designed for professionals who need to combine multiple documents into a single, organized file. Unlike traditional online services that upload your files to remote servers, Quick Merge processes everything locally in your browser using advanced WebAssembly technology.

How PDF Merging Works

Client-Side Processing: All PDF files are loaded directly into your browser's memory. No data is transmitted over the internet.
Format Preservation: We maintain original formatting, fonts, images, and layout integrity during the merge process.
Metadata Retention: Document properties, author information, and creation dates are preserved.
Security Assurance: Since files never leave your device, confidential documents remain completely private.

Frequently Asked Questions

Is there a file size limit for merging PDFs?

Yes, each PDF file must be under 50MB. This limit ensures smooth processing in your browser without consuming excessive memory. For larger files, we recommend compressing them first using our PDF compression tool.

Are my files secure during the merge process?

Absolutely. All processing occurs locally in your browser using WebAssembly. Your files never leave your computer, aren't uploaded to any server, and are automatically cleared from memory once the merge is complete.
