Real edit patterns

One instruction. A visible difference.

These before-and-after pairs show the kinds of focused changes contextual editing handles well. They demonstrate the task shape—not a guaranteed result for every source image.

How it works

The task is the interface.

KontextFlux removes model selection and prompt guesswork. Each mode asks only for the details needed to make one understandable edit.

Prepare privately

Your browser corrects orientation, reduces the longest edge, converts the image, and removes metadata before submission.

Name one change

Original text and new text, object and color, product and scene—the form turns concrete inputs into a controlled edit instruction.

Inspect the result

Use the draggable Before/After comparison, verify lettering and product details, then download the short-lived private output.

Focused tools

Start from the job you need done.

Each page opens the same production editor with the right task already selected, plus examples and limitations specific to that job.

Free without pretending

Capacity is bounded. The utility is not.

Anonymous AI generation has browser, network, and daily capacity limits so a small group of automated users cannot consume the entire provider budget.

When the AI queue is paused or your edit has been used, the browser tools remain available: resize, compress, convert formats, remove metadata, and copy the structured prompt.

There is no surprise account wall after generation and no watermark added to an eligible free result.

Privacy & review

Your image is a task input, not a social post.

Prepared inputs are scheduled for deletion after roughly one hour; results after roughly 24 hours. Files live in private storage and require the same anonymous browser session plus a short-lived signed token.

AI output is probabilistic. Always compare small text, logos, product claims, colors, hands, and identity 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.
