Selected images and results
When you select or drop an image, the application reads it locally to make previews and converted files. The conversion tools do not send image contents, previews, or filenames to our servers.
The application does not create an image account, server backup, or persistent conversion history. Clearing the list or leaving the page releases its references to selected files and results. Browser memory is managed by the browser; this does not guarantee immediate secure erasure from device memory.
Downloaded files stay on your device until you remove them. Your browser, operating system, backups, and any cloud-synced download folder are outside the application’s control.
Metadata inside images
JPG preserve mode keeps the complete source file, including any camera, location, or other metadata. Browser re-encoding may remove or change metadata, but the site is not a verified metadata scrubber. Check sensitive images before sending them elsewhere.
Requests made to load the website
Your browser requests the site’s pages, scripts, fonts, and other assets. The server or hosting network handling those requests can receive an IP address, requested URL, browser headers, and request time. Local image processing does not eliminate these normal website requests.
The application includes no analytics SDK, advertising pixel, tracking cookie, or image-upload endpoint. Any access or security logging configured by a deployment host is separate from the conversion application.
Cookies and browser storage
The application does not set cookies or store a conversion history. File lists, settings, and undownloaded results belong to the current page session. There is no account profile or saved conversion library to retrieve after you leave.
Reports and email
The contact page prepares a text report on your device. Preparing, copying, or downloading it does not send a support message. If you choose to email it, your email provider and the recipient receive the information you include.
Review the report before sending it and leave out private images or sensitive filenames. Direct privacy questions to [email protected].
Links and policy updates
Guides link to independent documentation. Those websites handle visits under their own policies; this page describes the jfif.net conversion application.
Changes to the application’s data handling should be reflected here before they are introduced. The date above identifies this version.
