Frequently asked questions

Can I edit PDF text free without Acrobat?
Yes. Select the words you want to change. Bold, italic, underline, font, size, and color apply to that selection or to what you type next. The rest of the line stays unchanged.
When should I convert to Word instead?
If you need heavy rewriting of long documents, convert PDF to Word, edit there, then convert back to PDF.
