PRACTICAL EXAMPLES

Try a real task.

Put a cover before your report

Choose the cover PDF and the report PDF, then use the arrows to put the cover first. Merge them into one document; every page follows the file order shown.

Combine chapters in reading order

Choose your chapter PDFs and arrange them before merging. Different page sizes and rotations are kept, so a landscape chart can stay beside portrait pages.

ABOUT MERGE PDF

A few things to know.

How do I merge PDF files?

Choose two or more PDFs, use the arrow buttons to arrange them and click “Merge PDFs”. Download your combined document as one PDF. Every page is included in the file order shown.

Is this PDF merger free and private?

Yes. No account, payment or upload is needed. Your files are read and merged in the browser on your device.

How many PDFs can I combine?

Combine up to 10 PDF files, with a maximum of 20 MB combined input and 50 pages in total. The merged output is limited to 50 MB. Smaller files help on mobile devices.

Will the page sizes and quality change?

Pages are copied without converting them to images. Original page dimensions, rotation, text and graphics are retained. File size may change because a new PDF is created.

Can I merge password-protected PDFs or forms?

Password-protected PDFs and interactive forms are not supported in this version. Use a flattened PDF copy for forms. Document bookmarks and attachments are not copied to the combined file.

Can I cancel or change the order?

Yes. Cancel stops processing and keeps your existing files. Reorder or remove files before merging again; making a change clears the previous download.
