About this tool
How to merge PDF files for free
Combining documents is one of the most common PDF tasks there is: stitching chapters into a single report, joining a signed contract with its appendix, or bundling scanned receipts for an expense claim. A PDF merger lets you merge PDF files free and end up with one tidy document instead of a folder full of attachments.
Using it is simple. Drop all the PDFs you want to join into the box above — you can add more at any time — then drag the rows to arrange them in the order you want. The first file in the list becomes the opening pages of the merged PDF, the next follows, and so on. Arrow buttons and a remove control give you precise, keyboard-friendly ordering on any device. When the sequence looks right, click Merge PDF and download the combined file.
Because this is a PDF merger online free tool that works in your browser, the pages are copied into the new document locally — no upload, no server, no waiting. Quality is preserved exactly: text stays selectable and formatting is untouched, since merging never re-compresses your pages. There's no sign-up, no watermark, and no limit on how often you can combine files. Once you've merged, you might want to compress the result for email, or split it again later.

FAQ
Frequently asked questions
How do I merge PDF files into one?
Drop two or more PDFs into the upload box, drag the files into the order you want them to appear, and click Merge PDF. The tool combines them into a single document with all pages in sequence, which you can download immediately.
Is there a limit on how many PDFs I can merge?
There's no fixed limit on the number of files. The practical limit is your device's memory — each file can be up to 50MB, and merging a very large number of big files at once may be slow on older phones. On a typical computer you can comfortably combine dozens of PDFs.
Can I change the page order before merging?
Yes. Each uploaded file appears as a row you can drag up or down, or move with the arrow buttons, so you control exactly which document comes first, second, and so on. You can also remove any file before merging.
Are my files uploaded to a server?
No. The PDF merger runs entirely in your browser. Your documents are combined locally on your device and never leave it, which makes this a private way to merge confidential files.
Does merging reduce quality?
No. Merging copies the original pages into a new document without re-compressing or re-rendering them, so the quality, text, and formatting of every page are preserved exactly.
