📌 What is EXIF?

EXIF (Exchangeable Image File Format) is hidden metadata baked into every image file. It records things like camera model, GPS coordinates, date taken, lens settings, ISO, and more. Every photo you shoot with a phone or camera has it — most people never see it.

File Data Editor lets you see all of it, and change any of it.

⚡ Quick Start

🏆 Recommendation — Use the Web Version

Open medit-site/medit.html in your browser. That's it. No Python, no install, no terminal. Works on any device with a browser. The CLI is a bonus for power users and batch automation.

---

🌐 Web Version [RECOMMENDED]

Usage

1. Open medit-site/medit.html in any browser
2. Drag & drop your image (or click to browse)
3. Pick a category from the sidebar
4. Click any field → type a new value → it saves instantly
5. Hit ↓ Download to get your edited image

Supported Formats

Format	View	Edit	Download with edits
JPG / JPEG	✅	✅	✅ Full support
PNG	✅	✅	⚠️ Re-downloads original
GIF	✅	✅	⚠️ Re-downloads original
WEBP	✅	✅	⚠️ Re-downloads original

EXIF embedding on download is JPEG-only due to a browser limitation. Use JPG for the full experience.
