Merge, split & reorder PDFs — without uploading them

Combine PDFs, pull pages out, and reorder them — right in this page. Nothing is uploaded; every page is rendered and rebuilt in your browser.

How it works: drop in one or more PDFs, drag the page thumbnails into the order you want (or delete the ones you don't), then download the merged file. With a single PDF loaded, you can also extract a page range into its own file.

How to use this tool

Use the dropzone below — that's the whole tool. (The downloaded version is the same tool as a file you double-click, no install or internet needed.)
Drop in one or more PDF files, or click the dropzone to browse for them.
Every page renders as a thumbnail. Drag pages into the order you want, or use the ▲/▼ buttons; click the × on any page to remove it.
Click Download merged PDF to save the result — or, with a single PDF loaded, enter a page range and click Extract as new PDF to pull just those pages into a new file.

What is this page?

This is the real PDF Merger / Splitter / Reorder — the same tool Untracked sells as a download — running free, right here in your browser. Your files are processed entirely on your own device: nothing is uploaded, no account is needed, and the page makes no network requests after it loads. You can verify that yourself: load the page, open your browser's network inspector, or even disconnect from the internet and keep using it.

Free page vs. the €9 download

Here (free): up to 3 files per day, counted privately in your own browser (localStorage). No cookies, no analytics, nothing that identifies you — the count lives on your machine, and clearing your browser's site data resets it.

The download (€9, once): the same tool as a single HTML file, with no daily limit — it runs offline forever, on any computer you own, even with no internet connection at all. Full details →

Questions people ask

Does my PDF get uploaded anywhere?

No. Page rendering, reordering, merging, and splitting all happen inside this page — there is no server and no network calls. Disconnect from the internet and it still works.

Does this work with password-protected PDFs?

No — a password-protected file is flagged and skipped, not decrypted. Remove the password in your PDF app first, then merge.

Is there a page or file-size limit?

No artificial limits — long documents render fine. The only cap on this free page is 3 files per day; the downloaded version has no cap at all.

Can I merge images or Word documents too?

No — PDFs in, PDFs out. Staying byte-precise with one format is what makes the merge reliable. (For images, see our resizer and HEIC converter.)

What's the difference between this free page and the paid download?

This page handles up to 3 files a day and lives on this website. The €9 download is the same tool as a single file with no limits — offline forever, on any computer you own.
