What LightPDF is

A PDF tool with reading comprehension attached. You can edit, convert, merge, split, compress and OCR a document, then ask questions about it, summarise it or translate it without leaving the page.

It suits everyday office PDF work rather than specialist document systems.

What you can do with it

  • Edit, convert, merge and split PDFs
  • Compress and manage pages
  • Run OCR on scans
  • Chat with a document to find key information
  • Summarise and translate content
  • Add signatures and annotations

Who it is for

  • Office users handling PDFs regularly
  • Students and teachers
  • Legal and administrative staff
  • Anyone processing cross-language documents

What to watch out for

  • Check OCR quality on scans before summarising or translating, since it drives accuracy
  • Contracts and legal clauses need professional review, not just AI extraction
  • Sensitive documents should not be uploaded without checking retention policy
  • Free tiers usually limit file size and features
