How many PDFs can I merge at once?

You can merge 2–10 PDF files in one job. Each file can be up to 25 MB, with a combined upload limit of 50 MB.

Can I choose the order of the merged PDFs?

Yes. Arrange the files in your desired order before selecting Merge PDF. The first file becomes the first pages of the resulting document.

Can I merge password-protected PDFs?

No. Encrypted PDFs are rejected by the merge tool. If you have permission and the password, unlock the PDF locally first and then merge the unlocked copy.

Does merging change the original PDF files?

No. The original files you select are used to create a separate merged.pdf result. Your local originals are not modified by the merge operation.

What should I use if I only want to remove or rearrange pages?

Use Delete / Extract Pages when you need to remove selected pages or create a PDF from selected pages. Use Split PDF when you want to separate a PDF into smaller files.

Merge PDF

Combine multiple PDF files into one document in the order you choose.

Files are processed in the order you choose. They stay private and are deleted after one hour.

Drop PDFs here or browse 2–10 files. Up to 25 MB each. Combined size up to 50 MB.

What this tool does

Merge PDF combines two to ten PDF files into one PDF document. The files are joined in the order you arrange them, so the first file becomes the first part of the finished document.

This tool is useful when separate documents need to become one file, such as combining reports, forms, application documents, or several related PDF pages into a single document.

Your PDF files are uploaded for processing and handled by the private server-side worker. Files and generated results are stored outside the public web root and are automatically deleted after the current one-hour retention period.
