Google Workspace Updates: Create, preview, and edit files directly in the Gemini app

You can now generate, preview, and edit documents, PDFs, presentations, spreadsheets, and more directly in Gemini.

Easily turn your handwritten notes into a PDF study guide, manually tweak content, highlight sections for Gemini to edit text or visuals, and even ask follow-ups.— Google Gemini (@GeminiApp) October 29, 2026

Until now, in Gemini, aside from editing text documents and code using Canvas, files could not be edited without first downloading them or saving them to Google Drive or the like. With this new feature, in addition to documents, files such as PDFs and presentations can also be generated, previewed, and edited within the chat.

The files that can be generated and edited are documents (text, Markdown, LaTeX), PDFs, presentations, and spreadsheets. You can easily convert handwritten notes into a PDF study guide, manually make fine adjustments, select the parts you want to edit and ask Gemini to change the text or visuals, or ask follow-up questions to refine the document. Generated and edited files can be downloaded in their respective formats, opened in apps such as Google Slides, and also uploaded to Google Drive via the "Export" button in the upper right.

PDF preview and editing are supported on both the web and mobile Gemini apps, but other formats (documents, spreadsheets, slide decks, Markdown files, TXT files, code) are supported only on the web.

This feature is available in all languages in which the Gemini app is available, to all users, including personal Google account users and Google Workspace users.

This is the result of instructing Gemini to create a PDF report that clearly summarizes the Linux kernel vulnerability "CVE-2026-98432," which has recently become a major security issue. A report laid out for easy reading has been created.

The displayed preview can also be edited directly.
