Frequently asked questions

Is merging PDFs free?

Yes, merging PDFs is completely free and requires no sign-up.

How many PDFs can I merge?

You can select several PDFs at once; as long as the total size is within the upload limit, they are combined into one file.

Can I change the file order?

Yes, you can arrange the files in any order before merging.

Are my files safe?

Uploaded files are used only for merging and deleted automatically afterwards.

Assemble attachments into one PDF in the right order

When an application form, cover letter, receipt and supporting documents are separate PDFs, this tool combines at least two files into one document. Pages are appended according to the file list shown after upload, so review that list from top to bottom before starting the job.

Merging brings the source PDFs together without serving as a compression step. After downloading the result, compare its total page count with the originals and inspect the boundary between each document to catch a missing or misplaced attachment.

Practical checklist

  • If the displayed order is wrong, remove a file and add it again at the correct point; the current uploader does not provide drag-to-reorder controls.
  • Use Compress PDF on the merged result if an email or portal imposes a size limit, because merging alone is not intended to reduce bytes.
  • Open the first page, the start of every attachment and the final page before sending the file; this quickly exposes a damaged, protected or accidentally selected PDF.
