Merge PDF Files
Combine several PDFs into one clean document — contracts with appendices, certificates with transcripts, chapters into a book.
Private by design: this tool runs entirely in your browser. Your files are never uploaded to a server, and nothing is stored.
Tap to add PDF files — or drop them here

How to use it
Add two or more PDFs. The list shows the exact order they will appear in the merged file.
Press Merge PDFs. Pages are copied across perfectly — nothing is re-typed or re-compressed.
Download merged.pdf. One file, ready to send.
Merging without the usual traps
Most "free" PDF mergers make you wait in a queue, stamp a watermark, or ask for your email before the download. ToolPixi merges on your own device instead: your documents are never uploaded, there is nothing to sign up for, and the output is a clean PDF with every page in its original quality. It is the same technology (pdf-lib) that professional tools use, running locally in your browser tab.
