What Makes a Good Free PDF Tool?

Not all 'free' PDF tools are equally free. Here's what to look for:

No email required: The best tools don't require you to create an account just to use basic features.

No watermarks: Watermarks on your processed PDFs defeat the purpose — you'd need to pay to remove them.

No file upload to servers (for privacy): Browser-based tools never send your files to anyone's server.

Reasonable file size limits: 50–100 MB per file is sufficient for most use cases.

No hidden 'daily limit': Some services allow 1–2 free conversions per day, then lock you out.
