Merge PDFs Instantly in Your Browser

Combining multiple PDFs into one document is a common need — assembling report chapters, combining a CV with cover letter and supporting documents, or joining scanned pages into one file. This tool uses pdf-lib, a powerful open-source JavaScript library, to merge your PDFs entirely in your browser. No files are uploaded to any server — all processing is local, fast, and completely private.

Maintaining PDF Quality

PDF merging using pdf-lib preserves the original quality of all content including text, vector graphics, images, and embedded fonts. The merged output is identical in quality to the source files. Page order is maintained exactly as you add the files — drag and arrange them before merging for precise control.

Frequently Asked Questions

Are my PDFs uploaded to any server?
No. Merging happens entirely in your browser using pdf-lib. Your files never leave your device.
How many PDFs can I merge?
There is no hard limit. Performance depends on file sizes and your browser's available memory. Keep total file size under 100MB for best results.
