How to Use These Prompts in the Gemini App — Step by Step
PromptPix does not edit photos itself. You copy a prompt from this library and use it inside Google's own Gemini app, with your own photo. The whole thing takes under a minute.
- Open the Google Gemini appUse the official Gemini app on your phone (or gemini.google.com on a computer) and sign in with your Google account. The photo editing feature is often called “Nano Banana”.
- Tap the + buttonAt the bottom of the chat screen, tap + and choose your photo from your gallery. Pick a clear photo where the face is well lit — better input, better edit.
- Copy a prompt from PromptPixCome back here, find a style you like and tap the big COPY button on its card.
- Paste the prompt and sendPaste the prompt into the Gemini chat box under your photo and tap send. Gemini will generate your edited photo in a few seconds.
- Adjust or downloadNot perfect? Ask for a small change in plain words (“make the background brighter”) or run it again. Tap the result to download and share it.
10 Tips for Better AI Photo Edits
- Start with a sharp, well-lit photo. Blurry or dark originals give blurry, dark results — no prompt can fix that fully.
- One face, facing the camera. Edits keep your likeness best when your face is clearly visible and not covered by sunglasses, masks or hair.
- Keep the “keep my face the same” line. Every PromptPix prompt includes an identity line — don't delete it, it's what stops the result from turning into a stranger.
- Change one thing at a time. If you want a different background AND outfit AND pose, do them in two or three rounds instead of one giant request.
- Regenerate instead of arguing. If a result looks off, generating again usually beats long correction messages.
- Mention the photo ratio. Add “vertical 9:16” for a phone wallpaper or DP, or “square 1:1” for a profile picture, at the end of the prompt.
- Festival edits pop with colour words. “Warm golden light”, “marigold orange” and “soft glow” give much richer festival results than plain descriptions.
- Don't over-edit group photos. AI edits are most reliable with one or two people; big group photos often distort hands and faces.
- Check the details before sharing. Look closely at fingers, jewellery, text and logos in the result — small glitches hide there.
- Save your winning combos. When an edit turns out great, save the prompt with the heart button here so you can reuse it on your next photo.
Stay safe: Only edit photos of yourself, or photos you have permission to use. Never upload someone else's photo without their consent. And beware of fake “Gemini editing” apps that ask you to pay or share an OTP — the real Gemini app is free for this, and PromptPix will never ask you for money, a password, or an OTP.
Frequently Asked Questions
Quick answers about PromptPix, the Gemini app, and how these prompts work.
Are these prompts really free?
Yes — completely. Every prompt on PromptPix can be copied and used for free, with no sign-up and no payment. The site is supported by advertising, which is how we keep it free.
Which app do I need?
The official Google Gemini app on Android or iPhone (or Gemini on the web). Its built-in image editing model is popularly known as Nano Banana. PromptPix is not affiliated with Google — we only write the prompt text; the editing happens in Google's app, in your own account.
Why did my result look different from what I expected?
AI editing is not exact — the same prompt can give slightly different results each time, and your starting photo matters a lot. Use a clear, well-lit photo, keep the “keep my face the same” line in the prompt, and simply generate again if the first result isn't right. Small follow-up requests (“brighter background”, “less blur”) also help.
Can I use the edited photo commercially?
These prompts are provided for personal use. What you may do with images you generate is governed by Google's Gemini terms, which can change and may differ by plan and country — please check Gemini's current terms before using an edited photo for business, ads or selling anything.
Do you store or see my photos?
No. PromptPix never receives your photos — you upload them directly into your own Gemini app. The only thing this site stores is your list of favourite prompts, kept in your own browser on your own device. See our Privacy page for details.
A site or app is asking me to pay to use these prompts. Is that you?
No. PromptPix is free and has no payment option at all. If another app or page asks you to pay to unlock our prompts, or asks for an OTP or password, it is not us — close it and come back here.
Can I request a new prompt style?
Yes! Tell us the look you want on our Contact page and we'll try to write an original prompt for it in a future update.
