Register images, apply common or individual settings, then convert selected files. Review processing status and current eligibility before downloading.
Image files, filenames and EXIF details stay in your browser and are not uploaded. Only unexpected application faults may send minimal technical codes, processing phase, app version, device class and browser family. Raw error messages, stacks, paths and IP addresses are not stored in the app's log database; saved error records are purged after seven days. Cloudflare infrastructure access data and any advertising or analytics are governed separately.
Download original files, outputs verified against current settings, or preserved previous results individually. Save currently valid outputs as a ZIP and export a CSV report for every registered image. Files stay in your browser; use individual downloads if a large ZIP fails.
Selections and settings exist only in page memory. Changing language, navigating, reloading or closing the tab resets them. A confirmation dialog is not guaranteed when closing the browser or entering a URL directly.
