Merge PDF Free — No Limits, No Signup

Merge PDFs for free with no restrictions. No daily limits, no file size caps, no account needed. 100% browser-based.

Most "free" PDF tools impose daily limits, watermarks, or require an account. This tool has none of that. Merge unlimited PDFs of any size, as many times as you want. No catches, no upsells — genuinely free.

Drop PDFs to merge

PDF files only

🔒100% Private — Your files never leave your device. All processing runs locally in your browser.

How It Works

Drag and drop multiple PDF files, reorder them visually, and merge them into a single document — all processed locally in your browser using the pdf-lib library. Your PDFs never touch a server.

The tool reads each PDF's internal structure, preserves all pages, bookmarks, and formatting, then combines them into one continuous document. You can rearrange the order by dragging files before merging.
