Clean a folder of Gemini exports locally.
Pro users can select multiple images, process the queue in the browser, and download every cleaned PNG in one ZIP.
Recommended batch size
GenClean caps batch selection at 25 files to keep memory usage predictable in desktop browsers. For larger folders, process them in smaller groups.
When batch cleanup is useful
Batch cleanup is built for repeated creative export work. If you generate ten thumbnail options, a set of campaign visuals, or several slide backgrounds, cleaning each file one by one can break your flow. A local queue lets you select the images once, process them in the browser, and download a single ZIP of cleaned PNG files.
The workflow is intentionally narrow. It is for visible Gemini corner marks on images you generated, own, or have permission to edit. It is not intended for third-party images, stock previews, or rights-managed assets.
How to prepare a folder
- Keep the original Gemini exports in one folder.
- Remove screenshots, duplicates, and non-Gemini files before selecting the batch.
- Use JPG, PNG, or WEBP files under the site limit.
- Run the batch while keeping the tab open.
- Review the ZIP before sending files to clients or publishing.
Batch cleanup vs single cleanup
Single cleanup is best when you are testing one image or preparing a final asset that deserves careful review. Batch cleanup is best when the task is repetitive: many candidates, the same visible corner mark, and the same desired output format.
The batch queue does not remove your responsibility to inspect results. It simply removes repetitive clicking. After the ZIP is ready, scan each file and reprocess any image with a difficult corner. This balance keeps the workflow fast without sacrificing quality control.
Performance notes
Large images and older devices can take longer. Keep the tab open while processing and download the ZIP once the queue completes. Since processing happens in your browser, performance depends on image size, available memory, and device speed.
What happens to the images
The selected files are processed in the browser. GenClean does not need to upload the image pixels to a remote server for repair. The serverless side is only for usage authorization and Pro entitlement checks. This helps keep batch cleanup practical for private folders and early-stage creative work.
Example batch scenarios
A marketer might generate a dozen campaign backgrounds, a YouTuber might generate thumbnail options for the next month, and a founder might create several product mockup scenes for a launch deck. In each case, the visible Gemini mark is a small repeated cleanup task that interrupts the creative workflow.
Batch cleanup is designed for that exact situation. It is not trying to be a general image editor. It helps you process a folder of permitted Gemini exports, inspect the results, and export the cleaned PNGs together. The value is speed, consistency, and less repetitive manual work.
How to avoid memory issues
Browser memory is finite, especially on laptops with many tabs open. If a folder contains very large images, process it in smaller groups. Keep the tab visible while processing, avoid refreshing until the ZIP is downloaded, and clear the queue before starting another large batch.
GenClean caps batch selection to keep the workflow predictable. That limit is intentional. A smaller reliable batch is better than a huge queue that crashes the browser or loses work before the ZIP is ready.
Quality checks
After processing, quickly scan the cleaned files at full size. If a file has residue, process that image individually and adjust the selected area. This keeps batch cleanup efficient without pretending every image background is identical.
