Merge PDF

Combine multiple PDF files into one

Processed in your browser — 100% private

Combining PDFs is one of the everyday tasks that most office suites handle badly and most online tools handle invasively. Our merge tool runs entirely in your browser — no upload, no account, no size cap beyond what your device can hold — and preserves bookmarks, form fields and page sizes from the source documents. Perfect for stitching contracts, chapters, invoices, scans or reports into a single clean file.

How to merge PDFs

  1. Drop the PDF files you want to combine into the window.
  2. Drag to reorder — the top file becomes the first chapter.
  3. Click "Merge" and download the combined PDF.

Supported formats

Input: any standard PDF (1.4 to 2.0). Output: a single PDF with all pages in your chosen order.

  • No watermark, no page count limit, no daily quota.

Merge PDF — Frequently asked questions

Are bookmarks and form fields preserved?
Yes. Bookmarks, interactive form fields and hyperlinks from each source PDF are preserved in the merged output.
Can I merge password-protected PDFs?
Not directly. Use our Unlock PDF tool first to remove the password (all local), then merge the unlocked files.
How many PDFs can I merge at once?
As many as your browser can hold in memory. In practice, merging 20–50 PDFs of moderate size is fast and stable.
Does merging reduce file size?
Not automatically. If the output is too large, run it through our Compress PDF tool afterwards.
