PDF Merge

How to use this PDF merge tool

  1. Select two or more PDF files.
  2. Files merge in the order they appear in the list.
  3. Click "Merge & Download" to get one combined PDF.

How does this work?

Your PDF files are loaded directly into your browser's memory and combined using a client-side PDF library — nothing is uploaded to any server. Files are merged in the order you select them.

Is there a file size limit?

Only the limits of your device's memory. Very large PDFs (hundreds of MB) may be slow in the browser, but there's no artificial cap like paid tools often impose.

Can I reorder the files before merging?

Currently files merge in the order you selected them in the file picker — reselect files in the order you want if you need to change it.

Does this preserve bookmarks or form fields?

Page content is preserved exactly, but interactive elements like fillable form fields or internal bookmarks may not carry over into the merged file.
