# Pages

> How pages work within a file and why page boundaries matter.

A file holds one page or many. An image is one page. A multi-page PDF is many. **anyformat handles page boundaries for you.** Two situations bring pages to your attention.

***

## Reviewing where a value came from

Open a document. anyformat shows the original beside the extracted data, and highlights the exact spot on the page where it found each value. Each value carries a **confidence indicator**: a signal of how sure anyformat is. [Confidence & accuracy](/guides/workflows/analytics-quality) explains what confidence means. Use this view to check why a value was extracted, and to correct it when it is wrong.

***

## When a value spans multiple pages

Pages trip you up when one thing splits across a page break. A table's rows continue onto the next page. A total sits on a different page from its line items. anyformat usually stitches these back together. If a result looks wrong, open the document and check the highlighted source. It names the page the value came from, so you can see whether a page boundary lost something.

## A note on usage

Usage is counted per page, so a 10-page document counts as more than a 1-page one. See [Usage & billing](/concepts/usage-and-billing) for details.
