Choosing the right PDF tool
Which PDF tool should I use first?
Start with the result you need: analyze and verify a file you received, compress, clean or protect one you are about to share, extract or convert content you want to reuse, or edit, build and fill a PDF you need to change.
Are these PDF tools free?
Most tools can be started for free. If a tool has a usage limit or paid option, it is shown before you commit to the workflow.
How are uploaded PDF files handled?
Each tool explains how it processes files. Avoid uploading confidential documents unless the tool page confirms that its handling matches your requirements.
Do I need an account?
You can start many tools without an account. An account may be required to save results, access history, or use ongoing workflows.
