Organize, Store & Share: Easily Merge Your Documents

Do you have multiple resources you wish to combine in one information package, or do you wish to organize, store, or neatly share documents using just one file? By using PDFen’s merge tools you can combine, convert and merge countless documents in one go.

How? Choose one of the 11 merge options which best fits your file type. Let’s run them down one by one.


Merge PDF

When? To combine individual PDF documents

How does it work?

  1. Go to ‘Merge’ and then to ‘PDFs’

  2. Drop up to 20 PDF or ZIP files into the software

  3. If you wish, add a cover page

  4. Press ‘convert’ and download directly.

Note: Merging multiple files into one larger file will only cost one credit, no matter the amount of files uploaded.


Merge files/images

When? If you’d like to combine JPG, JPEG, PNG, HEIF, HEIC, WEBP, TIFF, and/or TIF documents.

  1. Go to ‘Merge’ and then to ‘Files/images’

  2. Drop up to 20 compatible files into the software

  3. Pick the preferred page size and page orientation for your PDF.

  4. Click ‘show more options’ to adjust margins (white spaces) at either of the edges of the document

  5. If you wish, add a cover page

  6. Press ‘convert’ and download your result directly.

Note: converting files to PDF costs one credit each. Merging files always costs just 1 credit. Merging 5 images into one PDF will thus cost 6 credits (conversion+merging).


Merge multiple emails

When? In case you want to organize, archive or bundle your (important) emails for future reference.

  1. Go to ‘Merge’ and then to ‘Email’

  2. Drop up to 20 .eml, .msg, or .zip files into the software
