How to edit PDF?

You should know that PDFGear will eventually introduce paid features (which they are not disclosing at this time) and the free application was essentially establishing marketplace recognition and of course, a customer mailing list. One hopes they will not sell that mailing list to the dark web when money gets tight.

See the "Is PDFgear Really Free? And Why is that?" article for more insight.

Depending on the type of PDF editing that you have in mind, it may be addressed by suggestions in my recent post.

PDFgear is in the Mac App Store at present.

If you don't mind using an online PDF editor, you can use Sejda. Sejda is my go-to choice when I need to edit a PDF. You can use it for free (with limits). The free version is enough for me.
