How to merge PDF files
Put them in order.
Drag files into place or use the move buttons. Preview a document, remove extras, and check the total page count.
Merge and download.
Choose Merge PDF. Once your combined file has been checked, download it. Your original documents stay as they were.
Make the handoff simpler
A cover. A proposal. One PDF.
Keep the cover first, the proposal next, and the supporting pages last. The file order you see is the order of the finished document; pages inside each file keep their original sequence.
Your file order → your finished PDF
Useful by design
Fewer files. Fewer loose ends.
Your documents stay with you.
Reading, previews, and merging happen in your browser. Document contents and filenames are not uploaded to a server.
Free through the final download.
Add files, arrange them, and save your combined PDF without an account, subscription, or watermark.
PDF pages stay PDF pages.
Pages are copied rather than converted into screenshots. Page sizes, rotation, and crop boxes are checked before download.
A few things to know before you merge
Use 2–20 PDFs, up to 50 MB each and 100 MB combined, with no more than 2,000 pages in total. The output is limited to 100 MB. Large files may reach your device’s memory limit sooner.
Existing form appearances are flattened, so the merged PDF will not have editable form fields. Bookmarks, attachments, and digital signatures are not preserved. Password-protected PDFs and dynamic XFA forms are not supported; use an unlocked, flattened copy.
Before you bring it all together
Merge PDF questions, answered.
Can I merge PDF files for free?
Yes. PDFlet lets you merge PDFs and download the combined file for free. No account, subscription, or watermark is required.
How do I merge two PDF files into one?
Select both PDFs, arrange the file you want first at the top of the list, and choose Merge PDF. After the combined document is checked, choose Download PDF. You can add more than two files within the displayed limits.
Can I change the order before merging?
Yes. Drag the file cards into your preferred order or use the Move earlier and Move later buttons. You can also sort by filename or reverse the list. Pages within each PDF keep their original order.
How can I merge PDF files on Mac or a phone?
Open this page in a modern browser on Mac, Windows, iPhone, or Android. Choose PDFs available to your browser, use the move buttons to order them, and download the result. JavaScript is required; large documents may reach a phone’s memory limit sooner.
Are my PDF files uploaded to a server?
No. The files are read, previewed, and merged on your device. Document contents and filenames are not uploaded. The website still needs to download its own application files, and the optional sample set is a public download.
Will merging reduce PDF quality or change page sizes?
Pages are copied as PDF pages, without turning them into screenshots or applying image compression. Their size, rotation, and crop boxes are checked in the saved result. Form fields are flattened, and document-level features such as bookmarks, attachments, and digital signatures are not preserved.
Can I merge password-protected PDFs or forms?
Encrypted and password-protected PDFs are not supported. Save an unlocked copy first. Standard forms are flattened using their existing visible appearances, so fields will not remain editable. Dynamic XFA forms must be exported as regular, flattened PDFs before use.
How many PDF files can I merge?
Combine 2–20 PDFs. Each file can be up to 50 MB, the selected files up to 100 MB combined, and the total up to 2,000 pages. The resulting PDF is limited to 100 MB. Available memory on your device may impose a smaller practical limit.
Does PDFlet merge files automatically?
PDFlet combines the files after you choose them, set their order, and select Merge PDF. It does not watch folders, run scheduled merges, or read files without your selection. The download starts only when you choose it.
Can I merge PDFs offline or add Word and JPG files?
Offline use is not guaranteed because the page and processing files must load first. This tool accepts PDFs only. Convert Word documents or images to PDF before adding them; no conversion is performed by this merge tool.
