Merge PDF

The Merge PDF tool combines two or more PDF files into a single document, right inside your browser.

Add your files, drag them into the order you want, and download one clean PDF. Nothing is uploaded — every page is joined on your own device.

How to merge PDF files

1. Add your PDFs. Click the box or drag several files in at once.
2. Set the order. Use the up and down arrows to arrange the files exactly how the final document should read.
3. Remove any extras. Drop a file from the list if you added it by mistake.
4. Merge. Press the button and the pages are copied into one new PDF.
5. Download. Save the combined file — text stays selectable and images keep their resolution.

Why merge PDFs in your browser?

Most online PDF mergers upload your files to a server you have to trust. That is a real concern for signed contracts, bank statements, or scanned IDs.

This tool avoids the risk entirely by doing the work locally. Your documents never leave your computer, there is no queue, and there is no file waiting to be deleted later.

• Private: files are processed on your device, never uploaded.
• Order control: arrange files before merging so pages flow correctly.
• Lossless: pages are copied without recompression, so quality is untouched.
• Free and unlimited: no account, no watermark, no daily cap.

Common reasons to combine PDFs

Merging is handy whenever separate documents belong together as one file. Think of stitching a cover letter to a résumé, or gathering monthly invoices into a single report.

It is also the quickest way to assemble scanned pages that came out as individual files. Once combined, the document is far easier to email, print, or archive.

Other PDF and document tools

Merging is one step in a larger workflow, and the reverse job is just as common. When a single PDF needs to become several smaller ones, the Split PDF tool pulls out the exact page ranges you choose.

If you are starting from pictures rather than documents, the Images to PDF tool turns a set of JPGs or PNGs into one paginated file ready to merge. And when you only need the words out of a finished PDF, the PDF to Text Extractor pulls the text so you can reuse it elsewhere.

Frequently Asked Questions

Are my PDF files uploaded to a server?

No. The merge happens entirely in your browser using the pdf-lib engine, so your files are read from your device and never sent anywhere. This makes it safe for contracts, invoices, and anything confidential.

How many PDFs can I combine at once?

There is no fixed limit — add as many as your device's memory can comfortably hold. Very large batches of big files may slow down on low-memory phones, since all the work runs locally.

Can I choose the order of the merged pages?

Yes. Each file appears in a list you can reorder with the up and down arrows, and the final PDF follows that exact order. You can also remove a file before merging.

Will merging change the quality of my pages?

No. Pages are copied as-is, so text stays selectable and images keep their original resolution. Each page also keeps its own size and orientation, even if the source files differ.

Does it work with password-protected PDFs?

It can open PDFs that are not encrypted, and it ignores basic owner restrictions. A file locked with an open password must be unlocked first before it can be merged.

Does this work offline?

Once the page and its PDF engine have loaded, merging works without an internet connection because everything runs on your device. Nothing is uploaded, downloaded, or logged during the process.
