Everything you need to combine PDFs

100% private — nothing uploaded

All merging happens locally in your browser using pdf-lib. Your PDFs are never sent to any server.

Drag to reorder

Set the exact order your files should appear in the final PDF by dragging the thumbnail cards.

Unlimited files

Combine as many PDFs as you need in one pass — no per-merge or per-day limits.

Instant merging

No waiting for uploads or server processing. Files combine in seconds, even for dozens of documents.

Lossless output

Pages are copied directly from your source PDFs — text, images, and vector graphics stay exactly as they were.

Works with any PDF

Scanned documents, exported reports, forms, and image-based PDFs all merge correctly.

Three steps to your merged PDF

  1. 1

    Upload your PDFs

    Drag and drop two or more PDF files onto the page, or click to browse. Add as many as you need.

  2. 2

    Arrange the order

    Drag the file cards to set the order pages should appear in the final document. The number badge on each card shows its position.

  3. 3

    Merge and download

    Click Merge — your browser combines every PDF into a single file instantly. Download it directly, nothing is uploaded.

Frequently asked questions

Is this PDF merger free?

+

Yes, completely free with no limits on how many PDFs you combine or how often you use it. No account, no watermark.

Are my PDFs uploaded to a server?

+

No. Merging happens entirely in your browser using pdf-lib. Your files never leave your device — there's no server upload and nothing is stored.

How many PDFs can I merge at once?

+

There's no fixed limit — add as many files as you need. Very large batches may take a few extra seconds to process depending on your device.

Can I change the order of the merged pages?

+

Yes. Drag any file's thumbnail to reorder it before merging. Each PDF's own internal page order is kept intact.

Will merging affect the quality of my PDFs?

+

No. Pages are copied directly from the source files, preserving the original text, vector graphics, images, and fonts exactly.

Can I remove a file after adding it?

+

Yes. Hover over any file card and click the X to remove it from the merge before combining.
