## Choose between page editing, text extraction and conversion

PDF tools serve different purposes. Page operations reorganize a document; rendering makes an image of a page; text extraction reads the document text layer. A scanned page may look readable while containing only an image, so it needs OCR before ordinary text extraction can help.

## How to choose your next step

Check page order, orientation, margins and whether text is selectable. Review a sample of the exported pages before sharing the whole document.

## Common questions about pdf tools

### Why can a PDF look correct but produce scrambled text?

A page can position text visually without encoding its logical reading order. Columns, tables and individually positioned characters complicate extraction. Review the result, especially when it will feed a translation or summary.

### Will compressing a PDF always make it smaller?

No. A document may already use efficient compression. Reducing embedded image resolution can save space but also reduce detail, so compare the output at the size where it will be read.
