Edit Pictures with Prompt-Based AI Image Generator

Edit your AI-generated images with just one command. In PicLumen, you can enjoy such powerful AI magic with our newly integrated prompt-based AI image generator, FLUX.1 kontext. Whether you want to replace an object in the picture, change the pose/clothes of the person in your image, or correct text mistakes, the only thing you need to do is share your thoughts.

Smarter Edits through Image Logic

Automatically analyzes the relationships between elements in the image to ensure logical consistency after editing.

Pixel-Precise Element Control

Pinpoint any object in your image and edit it exactly based on your commands. Swapping colors, removing objects, or re-styling, the control stays in your hands.

Big Changes with Simple Prompts

Say goodbye to time-consuming edits. Simply describe what you want to change, and let Kontext do the rest. It’s faster, smarter, and saves hours of manual work.

Keep Character Consistency Across All Poses

Working on a story, game, or brand? PicLumen can keep your characters looking the same—no matter the pose, expression, or angle. Even with just one sideways image, you can generate a perfect front-facing shot or try new actions without breaking the look. It’s ideal for character concept art, comics, and Vtuber designs.

Edit Your Images with Smart Object Replacer

As a top-tier AI technology, our prompt-based AI image generator allows you to remove or modify objects in the image easily. Select one image that you generated with PicLumen, and tell us your idea about it, like deleting people in the background, changing a hat color, replacing the cup with a vase on the table, or converting wood to metal. Wherever there is imperfection, tell us how to make it perfect. And we will return to you a perfect one.

Change the Style of Your Image

FLUX.1 kontext is also a premium style changer. Once you have a specific style in mind but are not satisfied with the results, that’s okay. PicLumen can help you. Select the image you want to change the style of and enter the desired style. The highly trained Kontext can easily cover a wide range of styles, including those mentioned by you, such as Tim Burton, Pixar, Van Gogh, Takehiko Inoue, and more. Adding a filter or changing a style has never been easier!

Strange Letters? Not Anymore!

Do you often find spelling mistakes or strange characters in AI-generated book covers? No problem, this AI image editor can help you solve this problem. Editing images based on prompts makes it easy to correct text. For example, if your image contains “Piccllume,” you can tell Kontext, “change Piccllume to PicLumen.” In just a few seconds, you will get a new one with the correct text.

Remove BG and Swap a New One through a Prompt

Kontext can use AI to detect elements in the image, categorize and layer them, and remove the background layer while preserving the main object. Then, it will generate a new background based on the prompts you provide. This compensates for PicLumen’s inability to replace the background with ease.

Explore Creative Concepts and Co-Create with AI

Bring your ideas to life instantly. Upload a sketch or line art, tell us what effect you need, and PicLumen will automatically fill in the details for you. If you need product variants, our AI can generate multiple design versions with different colors, textures, or materials – all based on your commands. Once you need commercial-grade clear images, use this prompt-based AI image generator as an upscale. Effortlessly enlarge them and sharpen the final result.

Tips for Maxing Out the Effects of One-Line Magic

For a better experience using this prompt-based AI image generator, these practical tips can help you.

The key to mastering FLUX.1 kontext lies in efficient and precise text commands. Therefore, we have summarized a golden formula:

[Action] + [Object] + [Detail Constraints] + [Style/Environment]

❌ Incorrect example:

“Make the sofa better.”

We also prepared 6 high-success-rate tips & scenario templates for you:

Precise object positioning

Use the only object in the frame as a reference to position the item you want to change.

Portrait editing: Restrict the modification range

If you only want to change the color or material of an object, use “only” to limit the modification area.

Complex Scene Generation: Layered Description

Structure the image into “foreground-midground-background” to make it easier for AI to understand.

Stylization: Bind artist/era keywords

Style + Medium + Artist: Use this formula to ensure the image achieves the desired style.

Avoid AI hallucinations: Lock unchanged elements

If there are elements you don’t want to change, use “keep original” to prevent tampering.

Iterative Optimization: Incremental Correction Instructions

If you have an edited image but are not satisfied with minor details, select it for fine-tuning.
