Combine any number of PDFs into a single document, reorder them the way you want, and download — all inside your browser. Nothing you upload ever leaves your device.
All pages have been combined into a single file, in the order you set.
MergePilot lets you combine two or more PDF files into one document in seconds — no software to install, no account to create, and no limit on how many files or pages you merge. Unlike most online PDF mergers, MergePilot processes every file entirely inside your own browser, so your documents are never uploaded to a server.
MergePilot runs 100% client-side in your browser. There's no upload, no server storage, and nothing to worry about if your PDFs contain sensitive or confidential information.
Move any file up or down in the queue with a single tap, so the pages land exactly where you want them in the final document — no need to rename files first.
Select a batch now and add more later — every new file joins the queue at the end, ready to be reordered before you hit merge.
MergePilot totals your file sizes live as you build your queue, so you know roughly what to expect before you download.
Merge as many PDFs as you like, as often as you like. No sign-up, no watermark stamped on your document, no daily usage cap.
Once your PDF is merged, jump straight into PagePilot to remove or reorder individual pages — the two tools are designed to work together.
Tap "Select PDF files" or drag several documents into the box. Every file loads instantly and stays on your own device.
Use the arrows next to each file to move it up or down until the queue matches the order you want in the final PDF.
Hit "Merge PDFs," wait a moment while MergePilot combines them locally, then download your finished document.
