LightPDF

As PDF editors go, LightPDF is one that adds AI to the usual editing and conversion work. LightPDF is an AI PDF editor and converter that runs in a browser and also comes as mobile and desktop apps.

You can edit and convert files, summarize a document, translate it, run OCR on scanned pages, chat with a PDF, make slides with the PPT maker, or remove a watermark.

There is also an AI API, which is why LightPDF sits under Coding & Development rather than only with document tools.

That matters if you want to wire PDF features into your own software.

The basic tools are free.

The catch is that the free version limits file size and usage, and some advanced features need a paid subscription.

The online tools need an internet connection, so offline work means the desktop or mobile apps.

LightPDF suits people who handle documents often and want AI help without installing much.
