How to Edit PDF on Chromebook? (3 Easy Methods for 2026)

Chromebooks use ChromeOS instead, preventing traditional Windows .exe and Mac .dmg software installation. Many Chromebook users feel confused when they open a PDF file and need to edit it effectively. PDF editing on a Chromebook generally falls into two categories, depending on whether you need basic markup or direct content changes.

One category covers quick tasks like adding text boxes, highlighting sentences, or drawing signatures inside PDF documents. Another category focuses on directly modifying existing PDF text, swapping images, or performing OCR on scanned documents. A tool designed for one category usually cannot properly handle the other editing needs.

If you need general PDF editing tips, read our guide on how to edit a PDF or explore our Chrome PDF editor roundup instead. This guide shows how to edit a PDF on a Chromebook by choosing the right editing method for every editing requirement.

Method 1. Use the Built-in Gallery App (Free, Offline, No Install Needed)

Chromebooks generally include the Gallery app for opening and making simple changes to PDF files. This app is a good choice for basic PDF editing without installing another application on your Chromebook.

You can quickly place text boxes, highlights, and signatures on PDF files. This pre-built app works well for everyday PDF tasks like forms and simple document markups. Now, follow the steps below to edit your PDF with the built-in Gallery app on Chromebook:

Step 1. Open the Files app and double-click your PDF to open it. The PDF will open in the Gallery app by default.

Step 2. Next, to add the text, press the "Text Annotation" icon in the top toolbar and click anywhere on the PDF to add a text box. Start typing in the box to add the text.

Step 3. After that, select the "Annotate" option and choose a drawing tool. Next, drag your mouse pointer over the text to mark or highlight the text. You can also draw and place a signature on your PDF with the "Pen" tool.

Step 4. After the changes are finalized, press "Save" in the top right corner to apply changes.

Method 2. Use Online PDF Editors (Adobe Acrobat Web, iLovePDF, etc.)

Browser PDF editors help you edit PDF files without software and save time for ChromeOS users. Many people use these tools for quick PDF editing on their Chromebook. Smallpdf and other online PDF editors offer simple tools for many everyday PDF editing tasks online.

These tools are suitable for PDF files without private or sensitive information before uploading them online safely. Here is how to edit a PDF on a Chromebook using online PDF editors below:

Step 1. First, access an online PDF editor like Smallpdf and upload your PDF.

Step 2. After that, choose "Add Text" and draw on the PDF to create a text box. Type the text directly within the box.

Step 3. Next, select the "Highlight" feature and drag your mouse pointer over the PDF text to highlight.

Step 4. To add signatures, press the "Signature" tool and register a new signature. After that, you can use and reuse the same signature across PDFs. Lastly, press "Download" to save the edited version.
