Privacy at ImagePrepLab

Images and browser editing

The current editor is designed to select image files from your device, create a browser preview, and export the result from the page. Images are not intentionally sent to a ImagePrepLab upload service by the editor described on this site. You should still avoid loading sensitive files on a shared or untrusted computer.

Exports are re-encoded by the browser from the edited canvas. We verified in October 2026 that exports in JPG, PNG, and WebP formats do not carry the source file's EXIF or GPS metadata; exported PNG and WebP files are also fully opaque, with the canvas background filled in. Always check the exported file before sharing it.

Feedback and external services

The feedback link points to the project's GitHub issue tracker, and GitHub has its own account, privacy, and cookie policies; review those policies before submitting personal information or an image. Opening the issue form requires a GitHub account with access to that project repository — if the link does not open a form for you, the tracker is not publicly accessible at this time. External links are provided for convenience and are not controlled by ImagePrepLab.

Optional usage analytics

If you choose Allow analytics, ImagePrepLab loads Google Analytics 4 (GA4) and records one page view for the current page plus three editor events: editor_entered, image_processing_started, and image_export_succeeded. The editor entry event waits for a valid image to decode or a collage board to be activated. Processing starts only after an effective edit or image generation begins. Export success means the browser generated the image and the download link was triggered; it does not confirm that the file was saved.

Editor event parameters are limited to a task and an entry source. Tasks are Dimensions, Collage, Privacy, or unknown. Entry source is recorded separately as Dimensions, Collage, Privacy, direct, or unknown. The page view uses the page's canonical path without query strings or fragments. The site does not send images, image contents, file names, measurements, text entered in the editor, or URL query parameters to GA4.

GA4 also creates its standard visit and session measurements, such as first_visit for a new visitor, session_start, and user_engagement. Google Analytics may process standard browser and session information, including language, screen resolution, page title, page path, and its first-party analytics identifier. Google Signals and advertising personalization are disabled for this tag. Enhanced Measurement is disabled for the ImagePrepLab data stream, so it does not add automatic scroll, outbound-click, file-download, form, or embedded-video events.

The Google Analytics tag is not loaded unless you choose Allow analytics. Reject analytics leaves the editor fully usable and prevents analytics collection. Your choice is stored in this browser's local storage and can be changed here at any time. Google Analytics is provided by Google; see Google's privacy information.
