Why we picked Balloonz Files
We sat down with six PDF tools, the usual names you'll find in any list. Balloonz Files was the only one that didn't ask us to create an account, sign up for a trial, or upload a file to its servers. It converts Word, Excel, and PowerPoint to PDF, compresses files that are too big to email, and merges documents. All of it happens on your laptop, in a 12MB installer.
- ✓ Converts Word, Excel, and PowerPoint to PDF in one click
- ✓ Compresses PDFs locally — nothing is uploaded
- ✓ Merges multiple PDFs into one file
- ✓ Runs on your machine. Files stay put.
