Merge PDF Free Online

Combine PDFs and images into one document, put them in the right order and choose page ranges. Free, no login, no daily limit, and no file ever leaves your device.

✓ PDFs and images supported✓ No upload or loginReviewed 8 Sep 2026 by LyfPDF

Most tools that promise to merge PDFs for free are free up to a point: two or three tasks a day, then a subscription page. LyfPDF has no paid tier on this tool. Combine as many files as you like, as often as you like, without creating an account or handing over an email address.

That comes down to architecture rather than generosity. A typical online service uploads your document to its servers, processes it there and sends the result back — which costs bandwidth, which is why the limits exist. Here the merge is done by your own browser. Nothing is uploaded, so there is nothing to meter, nothing to queue, and no copy of your documents on somebody else's machine.

How to merge PDF files

Drop your files onto the page, or click to choose them. You can mix PDFs and JPG, PNG or WebP images in the same merge.
Put them in order: drag a row, or use A–Z, sort by date, or reverse. A–Z is a natural sort — scan2 comes before scan10.
To take only part of a file, type a range in its Pages box: 2-5, 8. Leave it empty to take everything.
Leave the bookmarks box ticked if you want a clickable contents list, name the output file, then click Merge & download.

What this tool does that most free mergers don't

Automatic bookmarks

The merged PDF opens with a clickable contents list built from your file names. On a bundle of twenty attachments, that is the difference between a usable document and a 200-page slab.

A page range per file

Take pages 2–5 of the first file and only page 1 of the second, in one pass. Elsewhere you would merge, then split.

PDFs and images together

Add JPG, PNG or WebP straight into the list. No need to convert them to PDF first.

Natural filename sorting

invoice2 before invoice10, the way you expect — not the other way round as in a raw alphabetical sort.

Actually unlimited

No daily quota, no cap on file count, no watermark, no account.

Nothing is uploaded

Your files stay on your device. No server copy to expire, leak or get scanned.

Common jobs

Assemble an application bundle — Receipts, certificates and forms in one PDF, with a bookmark per document so the reader can navigate.
Combine scanned documents — Several passes through the scanner? Add every file, sort by date, merge.
Bring a report and its appendices together — Take the report in full and only the right pages of each appendix using ranges.
Attach photos to a document — One PDF invoice plus three JPG photos — all in the same merge.
Gather chapters — Sort chapter1 … chapter12 correctly in one click thanks to natural ordering.

Merge and combine PDF files in the order you choose

Use this tool when several PDFs or images need to become one document. Reorder files before merging, include only the page ranges you need, and keep the originals unchanged while a new combined PDF is created locally in your browser.

Frequently asked questions

Is it really free?

Yes, entirely, with no daily limit. There is no account, no paid version of this tool and no watermark on the result. The site is funded by the advertising shown alongside the tool.

How many files can I merge at once?

We impose no cap. The only practical limit is your device's memory.

Are my files uploaded to a server?

No. The merge is performed by your browser and the final PDF is assembled on your device. No file passes through a server.

Can I merge only some pages of a file?

Yes. Type a range like 2-5, 8 in the Pages box on that row.

Can I mix PDFs and images?

Yes. JPG, PNG and WebP become pages at merge time, at their original size.

How do I change the file order?

Drag a row, use the arrows, or use one of the sort buttons in the toolbar.

Do I need to sign up?

No. No registration, no email and no login cookie.

Can I merge a password-protected PDF?

Only after you unlock it with the correct password in your PDF reader. LyfPDF does not bypass encryption or passwords; save an unlocked copy first, then add that copy to the merge.

Does it work offline?

Once the page has loaded, yes — the tool no longer needs the network to do its work.

Combine PDF files online when you need one document from several sources. To move individual pages between files, use Organize PDF and check the final reading order.
