Pure App Guide: How to Clean Up NanoBanana and Gemini Images

Pure is built specifically for cleaning up watermarked images generated by NanoBanana, which is the same workflow many people associate with Gemini image output.

It is not a general-purpose watermark remover for every image on the internet. The product is intentionally focused on the NanoBanana / Gemini use case, so the workflow stays fast and simple.

If you prefer using a browser, there is also a web version:

What Pure does

Import multiple images from your photo library
Batch-process NanoBanana / Gemini generated images
Review processed results in one grid
Open a larger single-image preview
Save the final image back to Photos
Keep everything offline on your device

What to expect before you start

Pure has a narrow and clear job:

It is for NanoBanana / Gemini image cleanup
It is not a universal photo editor
It is not an AI tool for every watermark style or every image source

If your images come from this exact workflow, Pure is a good fit. If they come from unrelated tools or different watermark styles, you should not expect the same result.

The 4-step workflow

The full process is simple: pick images, wait for processing, review the results, then save what you want.

Step 1: Open the app and choose images

On the home screen, tap the main button in the center and select the images you want to process.

You can choose multiple images at once
It works best when a batch comes from the same source
If this is your first time, test with a few images first

Step 2: Wait while the batch is processed

After you select your images, the app starts processing immediately.

You can see:

Current progress
Processed count versus total count
The current processing status

There is no manual box selection and no extra parameter tuning required.

Step 3: Review the batch results

When the batch is done, the processed images appear in a grid so you can quickly scan the whole set.

This screen is useful for two things:

Checking the overall batch quality
Picking one image to inspect more closely

If you processed many images at once, review a few representative examples before saving everything.

Step 4: Open one image and save it to Photos

Tap any result to open the larger preview, inspect it, and save it back to your photo library.

When checking the result, focus on:

Whether the original watermark area now looks natural
Whether edges, clothing details, or fine lines still look clean
Whether the brightness transition looks smooth

If the result looks right, save it directly from the preview.

A safer way to use it

If you are working on a large batch, this is the safer workflow:

Start with 2 or 3 sample images
Review a few different image types
Process the full batch only after the result looks right

That usually saves time and avoids redoing a large export.

When to use the web version

If your images are already on your computer, the web version may be more convenient:

Web version: https://pure.byu-young.top/

A simple rule:

If your images live in Photos on your phone, use the app
If your images are already on desktop, use the web version

Both versions are built for the same NanoBanana / Gemini image cleanup workflow.

FAQ

1. Is Pure a universal watermark remover?

No.

It is designed specifically for NanoBanana / Gemini images, not for every watermark case on the web.

2. Are my images uploaded to a server?

No.

Pure is designed around offline processing, so your images stay on your device during the workflow.

3. Why should I test a few images first?

Because even within the same NanoBanana / Gemini workflow, image content, compression, and export quality can still affect the final visual result.

Testing a small batch first is the safer approach.

4. Should I use the app or the web version?

Use the app if your images are already on your phone.

Use the web version if your files are already on your computer.

Final note

If you regularly work with NanoBanana / Gemini generated images, Pure gives you a focused and lightweight workflow.

It is not trying to solve every image-editing problem. It is trying to make this one job fast and easy.
