Nano PDF – A CLI Tool to Edit PDFs with Gemini's Nano Banana
The new Gemini 3 Pro Image model (aka Nano Banana) is incredible at generating slides, so I thought it would be fun to build a CLI tool that lets you edit PDF presentations using plain English. The tool converts the page you want to edit into an image, sends it to the model API together with your prompt to generate an edited image, then converts the updated image back and stitches into the original document. Examples: - `nano-pdf edit deck.pdf 5 "Update the revenue chart to show Q3 at $2.5M"` - `nano-pdf add deck.pdf 15 "Create an executive summary slide with 5 bullet points"` Features: -…
In plain words
Nano PDF is a command-line tool for editing PDF presentations using plain English prompts. It converts PDF pages to images, sends them to Google's Gemini 3 Pro Image model for editing, then converts the results back into the original document. Users can modify existing slides, add new ones that match the deck's style, and the tool preserves text layers for copying and searching. It processes multiple pages in parallel and includes Google Search integration for accessing current data.
