About PDF Merging

Our free PDF merge tool combines multiple PDF files into a single document entirely in your browser, with no uploads, no servers, and no software installation. Unlike online services that upload your files to the cloud, this tool processes everything locally on your device using modern web technologies, ensuring complete privacy and security. Perfect for combining contracts, invoices, scanned pages, or reports into organized multi-page PDFs.

The tool supports drag-and-drop reordering, unlimited file sizes (browser memory permitting), and preserves all original formatting, links, bookmarks, and annotations. Whether you’re combining 2 files or 50, the process is fast, secure, and works offline once the page loads.

🖋️ Professional Presentation: Create polished reports by merging cover pages, table of contents, body sections, and appendices in proper order.
📦 Archival Efficiency: Consolidate monthly statements, years of records, or project documents into searchable single files for long-term storage.
🔒 Total Privacy: Merge confidential contracts, financial records, or medical documents without exposing them to third-party servers.

Frequently Asked Questions

How many PDFs can I merge at once?

There’s no hard limit, but very large merges (50+ files or 500+ pages) may strain browser memory on older devices. For best performance, merge in batches of 10-20 files and combine the results.

Can I merge password-protected PDFs?

No. Password-protected PDFs must be unlocked first. Use our Remove PDF Password tool if you have the password, then merge the unlocked versions.

Will bookmarks and hyperlinks be preserved?

Hyperlinks within pages are preserved. Document-level bookmarks may not transfer due to PDF-lib library limitations. Internal page references will work if pages stay in sequence.

Can I merge other file types (Word, images) with PDFs?

This tool only merges PDF files. To include images, first convert them with our Convert Image to PDF tool, then merge the resulting PDFs.
