What makes KontextFlux different?

A focused editing workflow keeps the source image and one requested change at the center of the experience.

Context understanding

Structured task fields tell the model what to change and what must remain intact.

Precise control

Replace text, change a background, recolor an object, or describe one custom edit without prompt guesswork.

Private, practical results

Inputs and outputs are temporary, results are private, and local resize or format tools keep working without AI capacity.

How it works

  1. 1
    Upload your image

    Drag, paste, or choose a JPG, PNG, or WebP file.

  2. 2
    Choose one edit

    Use focused fields to describe the exact visible change.

  3. 3
    Generate privately

    Complete the abuse check and submit one protected job.

  4. 4
    Compare and download

    Inspect the before-and-after result before publishing.

Powerful image editing, without the heavy SaaS

Everything needed for a focused edit, with the expensive and distracting product layers removed.

Context-aware prompts

The editor builds preservation-focused instructions from clear task fields.

Fast task flow

Upload, configure, generate, compare, and download from one focused page.

Visual result review

A draggable before-and-after comparison helps catch altered details.

Local image utilities

Resize, compress, convert, and remove metadata directly in the browser.

Private by default

No public gallery, no permanent public result URL, and short retention windows.

Honest free capacity

Clear browser, network, and daily limits protect the shared provider budget.

Popular editing tasks

Start with the job you need done instead of choosing a model or learning a prompt syntax.

Frequently asked questions

Is KontextFlux really free?+

Eligible anonymous visitors receive one free AI edit in the current 24-hour window. Browser-local resize, compress, convert, metadata removal, and prompt-building tools remain free without AI capacity.

Do I need to create an account?+

No. The first eligible edit uses a signed anonymous browser session, Turnstile, and exact server-side quota checks instead of an account wall.

Are uploaded images public?+

No public gallery is created. Prepared inputs and generated results are stored privately for short retention periods and result access requires the same anonymous session plus a signed token.

Which image formats are supported?+

JPG, PNG, and WebP are accepted. The browser prepares a size-limited copy and removes metadata before submission.

Why can free AI editing be temporarily unavailable?+

Browser, network, daily-budget, and provider-cooldown limits prevent automated users or an overloaded upstream provider from consuming the shared free capacity.

Can AI alter small text or product details?+

Yes. Generated output is probabilistic. Always inspect labels, logos, product claims, colors, hands, faces, and other important details before publishing.

KontextFlux policy

How KontextFlux handles uploaded images, edit instructions, technical data, and short-lived results.

Updated July 30, 2026

The short version

KontextFlux is designed for one-off image edits without an account. We process the image and instruction needed to complete your request, protect the service from abuse, and delete short-lived files on a limited retention schedule.

Do not upload material that you do not have the right to process or information that you would not want sent to a third-party AI provider.

Information we process

  • The image you upload and the structured edit instruction you submit.
  • Prepared image details such as file type, dimensions, and size.
  • A random anonymous browser identifier stored in a signed, HttpOnly cookie.
  • Privacy-preserving hashes derived from network and browser characteristics for rate limiting and abuse prevention. We do not intentionally store raw IP addresses in the application database.
  • Job status, provider/model routing, error category, timing, and download events needed to operate and secure the service.
  • Cloudflare may process ordinary edge, security, and Turnstile telemetry under its own terms and policies.

Why we process it

  • To validate, queue, perform, store, and deliver the requested edit.
  • To enforce individual, shared-network, burst, and global free-capacity limits.
  • To detect unsafe or prohibited requests and investigate service failures.
  • To maintain security, reliability, and aggregate product performance without analyzing your image for advertising profiles.

AI providers

KontextFlux sends the prepared image and edit instruction to a third-party AI inference provider. The provider may route the request to an underlying model provider. Provider handling, retention, and model-improvement practices can change under their applicable agreements and policies.

KontextFlux does not claim that uploaded images are never used for provider improvement or training unless that claim is supported by the active provider agreement. Avoid uploading highly sensitive or confidential material.

Retention

  • Prepared input images are scheduled for deletion approximately one hour after upload.
  • Successful output images are scheduled for deletion approximately 24 hours after completion.
  • The normalized edit instruction is cleared from the job record after a terminal result or expiry.
  • Minimal operational records, hashes, error categories, and aggregate capacity counters may remain longer for security, abuse prevention, accounting, and reliability analysis.
  • Deletion is automated and may not be instantaneous during an outage or provider incident, but the service is not intended as permanent image storage.

Cookies and local browser data

The service uses a signed anonymous-session cookie to enforce free usage and protect private job results. The editor may also use browser memory or local storage for non-sensitive interface preferences. We do not use an account cookie or cross-site advertising cookie at launch.

Sharing

We share data with infrastructure and inference vendors only as needed to operate the service, comply with law, prevent harm, or protect legal rights. We do not sell uploaded images or edit instructions.

Your choices

  • Close or reset the editor to discard the browser's local preview.
  • Do not submit the AI job; local resize, compression, conversion, and prompt-building tools can run in your browser.
  • Contact hello@kontextflux.com about a privacy request and include the job ID if it is still visible. We may be unable to identify anonymous use after short-lived records expire.

Changes

We may update this policy when providers, features, or legal requirements change. The updated date at the top identifies the current version.
