About

Limpide is a small, open-source toolkit for image metadata and format conversion.

Web app (browser, no upload)

• View EXIF — inspect embedded metadata (camera, GPS, dates, etc.)
• Strip EXIF — remove camera EXIF, GPS, ICC color profile, and JFIF metadata
• HEIC to JPEG — convert Apple HEIC/HEIF files (EXIF and GPS preserved)
• ZimmyGpx — set the date on a folder of JPEGs, or shift every photo by ±x seconds (no GPX file)

Processing runs entirely in the browser. There is no upload endpoint, no database, and no server-side storage. The logic lives in web/app.js and can be reviewed directly.

CLI (Python, local or batch)

• strip-exif — remove EXIF from JPEG, PNG, WebP, TIFF
• convert-heic — convert HEIC/HEIF to JPEG (preserves EXIF and GPS)
• zimmy-gpx — set or shift EXIF dates on a folder of JPEGs (no GPX file)
