The best free AI image generator for most phones is the Google Gemini app. It is free on iPhone and Android and makes and edits images from a simple sentence. If you have an iPhone 15 Pro or newer, Apple’s Image Playground is already on your phone. On a recent Samsung Galaxy, Galaxy AI is built into the Gallery app.
Below you’ll find 12 free options compared in one table, what “free” really means for each, how to put yourself in a picture safely, how to extend a photo, and what to do when an app refuses to generate anything.
Free AI image generators at a glance

Check your phone first: AI image tools you may already have
1. Apple Image Playground (iPhone)
Image Playground is Apple’s free AI image app, part of Apple Intelligence. It turns a description, a photo or a person from your Photos library into a new image, and you can change it by describing edits or circling parts of the picture.
According to Apple’s Apple Intelligence requirements page, it needs an iPhone 15 Pro or 15 Pro Max, any iPhone 16 or later, iPhone Air or iPhone Duo. Your device and Siri language must be a supported language, it is not available on iPhones bought in mainland China, and daily limits apply because some images are made on Apple’s servers.
2. Samsung Galaxy AI (Drawing Assist and Generative Edit)
On a supported Galaxy, open a photo in Gallery > Edit > Photo assist. From there you can Move an object, restyle the photo with Style, or use Create to sketch something, then tap Generate and Save as copy. Samsung’s Generative Edit guide says it needs One UI 6.1 or later, a Samsung account and an internet connection, and the result gets a Galaxy AI watermark.
Samsung says its basic Galaxy AI features are free. Supported phones include the Galaxy S21 to S26 series, recent Z Fold and Z Flip models and some A-series phones.
Pixel owners: Pixel Studio no longer makes images
If you used Pixel Studio on a Pixel 9 or Pixel 10, Google’s Pixel help page now says you can no longer create images in it. Your old projects can still be viewed and downloaded, and Google points you to the Gemini app instead. That’s the next entry.

3. Google Gemini: best free all-rounder
Gemini’s free plan includes image generation and editing with Google’s Nano Banana 2 model. On Android, Google’s steps are: open Gemini, tap the menu at the top left, choose Images, then pick a template or type a prompt. To edit, upload a photo and describe the change. You can even upload several images and ask Gemini to combine them.
Limits aren’t a fixed number of pictures. Google describes them as “standard limits” that refresh every 5 hours up to a weekly cap, and you can see where you stand in Settings > Usage Limits. Free downloads are 1K resolution; paid plans get 2K. Every image carries Google’s hidden SynthID watermark, and the visible mark can be turned off in Settings > Media Watermark in most countries.
4. ChatGPT: best for long, detailed prompts
The free ChatGPT plan includes “limited image creation”, and paid plans raise the limit. In the app you simply describe the picture in the chat, or attach a photo and ask for a change. Because it is a chat, you can refine the picture step by step (“make the sky darker”, “now add a cat on the sofa”).
If you see “You’ve hit the free plan limit”, you’ll need to wait until the limit resets or upgrade.
5. Meta AI: easiest way to put yourself in a picture
In the Meta AI app, start your message with “imagine” or “create an image”. Meta’s help page says adding “me” or “myself” puts you in the image. You can also upload a photo to edit. It isn’t available in every country.
6. Microsoft Copilot
Copilot creates images from a prompt and edits your own pictures: tap +, choose Add images or files, pick a photo and describe the change. Microsoft says it keeps images for up to 18 months, so think about that before uploading personal photos.
7. Adobe Firefly
The Firefly mobile app gives signed-in users free daily generations, including some partner models. It is strongest at AI image edit jobs on photos you already have, such as Generative Fill to add or remove things in part of a picture.
8. Canva
Canva’s Magic Media turns a prompt into an image: open Magic Media, choose the Images tab, describe what you want, pick a style and tap Generate. Free accounts share a limited monthly AI allowance, and Canva pauses you briefly once it runs out. It’s the best pick when the image is going straight into a poster, post or slide.
9. Leonardo.Ai
Leonardo gives free users 150 tokens a day that reset every 24 hours and don’t roll over. Its FAQ says free users may use their images commercially, but anything made with Private Mode off is public. It has iPhone and Android apps.
10. Ideogram
Ideogram gives 30 free credits a week, but only if you sign in with Google, Apple or Microsoft. Free images are public. The iPhone app can make variations of an uploaded photo and expand an image to a new shape.
11. DeepAI
The DeepAI image generator works in your phone’s browser with no sign-up. Type a prompt, choose a model and style, and generate. DeepAI says commercial use is allowed and treats outputs as public domain. Free use includes a limited number of HD images.
12. Fotor
The Fotor AI image generator runs in the browser and in its iPhone and Android apps. Each image costs one credit; you get free daily credits, plus 5 extra for signing up in the app. Fotor allows commercial use and includes AI Expand.
How to incorporate yourself in an AI image generator
- Meta AI: type “imagine me as an astronaut on Mars” (any scene works).
- Gemini, ChatGPT or Copilot: upload a clear, well-lit photo of your face, then describe the new scene. Ask it to keep your face and hairstyle the same.
- Image Playground: choose a person from your Photos library. If the result doesn’t look like you, try a different photo where your face is front-on.
Privacy check before you upload a selfie: Leonardo and Ideogram make free images public, and Copilot keeps images for up to 18 months. Only give an app access to the photos it needs; our guide to changing app permissions on iPhone shows how to limit photo access to selected pictures. Never upload photos of other people without asking them.
How to extend a photo with an AI image extender
An AI image extender (also called outpainting or “expand”) fills in what’s beyond the edges of a photo, which is handy for turning a portrait into a wallpaper or a banner.
- Canva: Magic Expand stretches an image to a new size or shape.
- Fotor: AI Expand does the same in the app.
- Ideogram and Leonardo: expand to a new aspect ratio, or “unzoom” in Leonardo.
Expanded images can fill your storage fast. If space is tight, see how to manage iPhone storage.
Free limits and watermarks: what “free” really means
- Limits reset on a timer. Gemini refreshes every 5 hours, Leonardo every 24 hours and Ideogram weekly. Canva uses a monthly pool.
- Some free images are public. On Leonardo (with Private Mode off) and Ideogram’s free plan, other people can see what you make.
- Watermarks. Samsung adds a visible Galaxy AI mark. Gemini adds an invisible SynthID mark and Content Credentials that stay even if you hide the visible one. Removing an AI label to pass a picture off as real is a bad idea.
- Commercial use. Leonardo, DeepAI and Fotor say their free images may be used commercially. For anything else, read the app’s terms before selling a design.
How to write a better prompt
Every one of these AI image generation tools does better with a clear brief. Use this order:
- Subject: who or what (“a golden retriever puppy”).
- Action and setting: what is happening and where (“running on a beach at sunset”).
- Style: photo, watercolor, 3D render, anime or pencil sketch.
- Framing: close-up, wide shot, square or tall (for a phone wallpaper).
- Fix, don’t restart: ask for one change at a time (“brighter”, “remove the person on the left”).

AI image generator not working? Common fixes
- Image Playground is missing: check your model is on Apple’s supported list and that your device and Siri language match a supported language.
- Image Playground shows no people: Apple Community users report that the People section stays empty until Photos finishes recognizing faces. Give Photos time to finish, then try again.
- ChatGPT says you’ve hit the free plan limit: wait for the reset or try another app from the table.
- Samsung says it can’t generate this content: some subjects are blocked. Try simpler wording.
- Gemini stops making images: check Settings > Usage Limits; you may have used your allowance until the next refresh.
