Effacer l'EXIF / éditer les métadonnées
Supprimez GPS, numéro de série d'appareil photo et horodatages — ou ajoutez vos propres mentions de copyright, crédits et mots-clés IPTC en lot. Tout dans votre navigateur.
Déposez les photos n'importe où sur la page
JPG, PNG, TIFF — le glisser de dossiers et le collage fonctionnent aussi. Pour le HEIC, utilisez le convertisseur HEIC d'abord.

Qu'est-ce que l'EXIF et pourquoi s'en soucier ?
Every photo your phone or camera takes silently records extra information inside the image file — called EXIF metadata. This includes the GPS coordinates where the photo was taken, your camera's serial number, the exact timestamp, the editing software you used, and often a small embedded preview of the image.
Some of this is useful (knowing the date a photo was taken). Some is a real privacy hazard:
- GPS leaks your home address. Post a photo of your dog on social media and the EXIF tells anyone with a free tool exactly where you live.
- Miniature intégrées sometimes show the original image even after you crop or blur the visible photo — the thumbnail wasn't updated.
- Camera serial numbers can be used to link otherwise anonymous photos back to you across the internet.
Most social platforms (Facebook, Instagram, Twitter) strip EXIF on upload. But many don't — and direct shares (email, SMS, file transfer, cloud links) preserve the metadata exactly as your camera wrote it.
Pour les créateurs — l'autre versant
If you're a photographer, the goal is the opposite: you want to add metadata. Embedded copyright, artist credit, IPTC keywords, and descriptions travel with the file and are the digital equivalent of signing your work. Stock-photo sites and image search engines read these fields. Clients can identify the creator of an orphan file. Search inside your own folders by keyword.
This tool batch-applies a template you've saved (e.g. "© 2026 Studio Name, all rights reserved, keywords: editorial, lifestyle") to every photo you drop — no need to edit each one in Lightroom.
F.A.Q.
Will GPS really be removed from the file?
Yes. The GPS block is deleted from the EXIF data and the file is rewritten without it. You can verify by re-dropping the output file — the metadata viewer will show "no GPS" or "no metadata" depending on your strip settings. For maximum privacy, also enable "Strip everything" — that wipes camera serial, timestamps, embedded thumbnails, and editing software too.
What's the difference between "Strip GPS" and "Fuzz GPS"?
Strip GPS removes the location data entirely — viewers see no location. Fuzz GPS rounds the coordinates to about 0.01° resolution (~1 km / city-level). Useful when you want viewers to know roughly where a photo was taken ("somewhere in Montréal") without revealing your exact home or hotel block.
Can I add copyright info to all my photos at once?
Yes. Fill in the Copyright, Artist, Description, and Keywords fields, then click "Apply to all". The same values are written to every JPG you've dropped. Save the form as a named preset so you can re-apply it next time with one click. Presets are stored in your browser's local storage — they don't leave your device.
Why is metadata writing only on JPG, not PNG?
Standard EXIF is a JPG/TIFF/HEIC convention; PNG has its own metadata format (tEXt/iTXt chunks) which is rarely used in practice and not widely supported by photo workflows. For PNG input we strip all metadata (privacy mode), but we don't write new fields. If you need PNG copyright tagging specifically, convert to JPG first using the image converter.
Can I shift photo timestamps to fix a camera with wrong timezone?
Yes — use the "Shift dates" field to add or subtract hours from every timestamp in the EXIF. Useful when you forgot to update your camera's clock for daylight savings or a flight to another timezone. Use 0.5 for half-hour offsets (Newfoundland, India).
Do the templates / presets sync between my devices?
No — they're stored in your browser's local storage on the device where you saved them. This is on purpose: we don't have user accounts and your presets stay private. If you want the same preset on another device, save it by filling in the fields manually on that device too.
