To generate images with AI, you write a text prompt describing what you want and the model renders it. To edit an image with AI, you do the opposite: you start from a photo you already have and tell the model what to change. Both are useful, and the practical difference matters more than most guides admit — generation invents from scratch, while editing has to respect the picture that's already there. This guide walks through both, plus two adjacent jobs people always need next: upscaling a small image and removing its background.
We build Kvora, Torki's image engine, so we'll use it for the concrete steps. The principles, though, carry over to most modern image tools.
The two things "AI images" actually means
People say "AI images" to mean two different jobs:
- Text-to-image (generation): You describe a scene and the model creates a brand-new picture. There's no source image — only your words.
- Image-to-image (editing): You upload an existing photo and ask for a change — a new style, a different background, a cleaned-up version. The model transforms the pixels you gave it rather than starting blank.
This distinction is the single most important thing to get right, because tools vary a lot here. Some are excellent at generating but can't truly edit an image you hand them; others do both. Torki does both: it generates from text and edits existing images (image-to-image), and it also upscales images, removes or replaces backgrounds, and can analyze a photo you upload (vision). Below, each gets its own short recipe.
How to generate an image from a text prompt
Start in chat and just ask. A request like "create an image of a quiet reading nook by a rain-streaked window, warm lamp light, cozy" is enough to get a first result. To get a result you actually want, structure the prompt.
A prompt formula that works
Most strong prompts cover five things, roughly in this order:
- Subject — what's in the frame ("a golden retriever puppy").
- Context / setting — where it is ("on a wooden porch at sunset").
- Style — the look ("watercolor," "cyberpunk," "photorealistic," "line art").
- Composition — framing and lens cues ("close-up," "wide shot," "shallow depth of field").
- Lighting / mood — ("soft golden-hour light," "moody and dramatic").
In Torki you can lean on built-in style presets (realistic, anime, cyberpunk, 3D render, line art, oil painting, watercolor, minimalist) and pick an aspect ratio — square (1:1), landscape (16:9), portrait (9:16), and several others — so you don't have to encode all of that in words. Choose the aspect ratio for where the image will live: 1:1 for a profile picture, 16:9 for a header, 9:16 for a phone screen or story.
Prompt tips that consistently help
- Be specific about the things that matter, vague about the things that don't. "Red ceramic mug, steam rising" beats "a nice mug."
- Name a style explicitly. "Photorealistic" and "flat vector illustration" produce wildly different images from the same subject.
- Add lighting words. Lighting does more for mood than almost any other token.
- Iterate, don't restart. Generate, see what's off, and adjust one variable at a time — change the style, then the composition, then the lighting.
- Keep a known-good prompt. When something lands, save the wording so you can reuse the structure.
A quick honesty note: AI image models render text inside images inconsistently, struggle with exact counts ("exactly seven birds"), and sometimes mangle hands and fine symmetry. Treat the first generation as a draft.
How to edit an existing image (image-to-image)
Editing is where workflows usually get stuck, because not every tool can take your photo and change it. In Torki, you attach a photo and describe the change in plain language — for example, upload a portrait and say "make this an anime illustration" or "give it a 70s film look." The edit applies your style or instruction while aiming to preserve the real subject — the face, expression, and background — rather than regenerating a different person.
There are ready-made transform templates for common edits (think portrait, anime, comic, oil painting, and similar looks), so you can get a consistent result without hand-tuning a prompt. And because it's conversational, you can keep going: edit, look, refine. Practical editing tips:
- Describe the change, not the whole picture. Say what's different ("swap the daytime sky for a sunset"), not everything that should stay the same.
- Start from a good source. A sharp, well-lit original edits far better than a blurry one.
- Generate a few variations and pick the best, rather than expecting one perfect output.
How to upscale an image
If an image is too small — an old logo, a low-res photo, a generated picture you want to print — upscaling increases its resolution and sharpness. In Torki, point the upscaler at any generated or uploaded image to enlarge it (2x or 4x). The realistic expectation: upscaling recovers and sharpens detail impressively, but it can't invent information that was never captured, so a tiny, heavily compressed source has limits.
How to remove or replace a background
Background removal is the workhorse edit for product shots, headshots, and design assets. Torki can remove a background to transparent, or replace it with a solid color or another image. The usual flow: remove the background, drop the subject onto a clean backdrop, and you have a usable product or profile image in seconds. Subjects with clean edges (a person, a bottle) cut out more cleanly than wispy ones (loose hair, fur, smoke), so check the edges before you ship it.
How AI image tools compare
Different tools are built for different jobs. Here's a fair, high-level view — verify exact specs and pricing on each vendor's site, since these move quickly.
| Tool | Generate from text | Edit existing images | Best for |
|---|---|---|---|
| Torki | Yes | Yes — image-to-image, upscale, background removal, vision | An all-in-one app: image generation and editing alongside chat, research, voice, and Google/Microsoft connectors |
| ChatGPT (OpenAI) | Yes | Yes — instruction-based, in-chat | A large ecosystem with native generation and conversational editing |
| Google Gemini | Yes | Yes — strong editing | Editing with character/object consistency, plus deep Google Workspace ties |
| Midjourney | Yes | Yes — strong in-app editor | Top-tier aesthetics, but effectively no first-party integrations |
| Anthropic Claude | No native generation | No native pixel editing | Writing, reasoning, and analyzing images; can build charts/diagrams as code |
| Perplexity | Yes (via third-party engines) | Largely absent | Cited research; image generation is a secondary feature |
The takeaway: if you only generate, several tools are excellent. If you need to edit your own photos — restyle them, upscale them, cut backgrounds — that's a narrower field, and it's where having generation and editing in one place pays off. Torki keeps all of it next to your chat, research, and agentic actions, so an image can flow straight into a document or design without tool-switching.
A simple end-to-end workflow
- Generate a first draft from a structured prompt.
- Edit it (or your own photo) to fix style, mood, or details.
- Remove the background if you need the subject isolated.
- Upscale the final pick for print or a hi-res screen.
That loop covers the vast majority of real image jobs, from a social post to a product mockup.
FAQ
What's the difference between generating and editing an image with AI?
Generation creates a new image from a text prompt with no source picture. Editing (image-to-image) starts from an existing image and changes it. Torki does both.
Can AI edit a photo I already have?
Yes. In Torki you upload your photo and describe the change in plain language — restyle it, change the background, or upscale it — while it works to preserve the real subject.
Can I remove a background and upscale an image too?
Yes. Torki includes background removal (to transparent or a new background) and 2x/4x upscaling, alongside generation and editing.
Do generated images have a watermark?
Images on the free plan carry a Torki watermark; paid plans don't. Daily image limits also vary by plan.
Where can I try it?
The free tier lets you generate and edit a handful of images per day to see how the workflow fits you. You can explore plans on the pricing page when you're ready for more.
Try it on the free tier
The fastest way to learn AI image generation and editing is to run a few prompts yourself. Start free, generate a draft, edit it, remove a background, and upscale the result — the whole loop takes a couple of minutes. When you outgrow the free limits, the plans scale up your daily images and remove the watermark.
