How to use Compress PDF online

SENNA PDF helps you reduce PDF size by preparing output choices in browser memory first. You can compare original, high, medium and low-size versions before downloading the final file.

  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.
