# Mark up a photo or PDF on mobile

Add notes directly to a visit photo or uploaded PDF from the mobile app — drawing, text, arrows, boxes, and circles. Technicians can also erase marks, undo or redo changes, and rotate or flip photos before saving.

> **Where to find it:** Mobile app > Visits > open a visit > Files > tap a photo or PDF > **Markup photo** or **Markup PDF**

## Mark up a photo

1. Open the visit and find the **Files** section.
2. Tap the photo you want to mark up.
3. Tap **Markup photo**.
4. Pick a tool and add your marks. Use **Undo** and **Redo** if needed.
5. To rotate or flip the photo, open **Rotate & Flip**, make the change, and choose **Done**.
6. Tap **Save**.

The marked-up photo replaces the version shown in Essential, and the original is kept so it can be restored later.

## Mark up a PDF

1. Open the visit and find the **Files** section.
2. Tap the uploaded PDF you want to mark up.
3. Tap **Markup PDF**. The current page opens directly in the editor.
4. Add drawing, text, arrows, boxes, or circles. Use **Undo** and **Redo** if needed.
5. If the PDF has more than one page, use the page arrows in the editor to switch pages and mark up each one — every page you mark saves together.
6. Tap **Save**.

Rotate and flip aren't offered for PDF pages.

## View or restore the original

A photo or PDF that's already been marked up shows **Edited**.

1. Open the file and tap back into the markup editor.
2. Tap **Original** to compare it with the edited version.
3. While viewing **Original**, tap **Revert** to restore it and remove the marked-up version.

Keep an internet connection while saving. If a save fails, the editor stays open so you can try again without losing your marks.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://learn.withessential.com/field-operations/mobile/mark-up-a-photo-on-mobile.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
