How to use Merge PDF online

Merging PDF files is essential for combining reports, scanned documents, application papers, office records or assignments into one final file. SENNA PDF lets you add files, preview each page, reorder pages and export one clean PDF locally in your browser.

  1. Select your file from the upload area.
  2. Let SENNA prepare the visual page workspace.
  3. Preview, reorder, rotate, delete or select pages if needed.
  4. Prepare the final output and download after checking the size.

Why this workflow is different

Most PDF tools force you to upload the same file again for each action. SENNA PDF keeps the document in one workspace so you can complete multiple fixes before final export.
