Image Batch

Paste multiple image prompts, and the extension drives gemini.google.com for you — generating one image per prompt and downloading each PNG the moment it is ready, with a ZIP of the full batch at the end.

How it works

A small side panel that sits next to Gemini and automates the busywork for you.

Multi-prompt input

Paste as many prompts as you want — one per line. The queue runs top to bottom.

One image per prompt

Each prompt is typed into Gemini, submitted, and waited on until the image finishes rendering.

Auto-download

Every finished image is saved as a PNG into a dated image-batch folder — no clicking.

ZIP of the batch

When the queue ends, the whole run is bundled into a single ZIP file as well.

Installation

No Chrome Web Store account required. Load it unpacked in under a minute.

  1. 1Download and unzip the extension file.
  2. 2Open chrome://extensions in Chrome (or Edge, Brave, Arc, Opera).
  3. 3Turn on Developer mode in the top-right corner.
  4. 4Click "Load unpacked" and select the unzipped folder.
  5. 5Open gemini.google.com in a tab and start a chat.
  6. 6Click the extension icon — it opens as a browser sidebar next to Gemini.
  7. 7Paste one prompt per line in the sidebar, then hit Start batch.

Good to know

  • Keep the Gemini tab open while the batch runs — the extension types into that page.
  • It automates Gemini's own interface, so a Google redesign can require selector updates.
  • Leave a few seconds between prompts to stay within Gemini's rate limits.
