Overview

The ExifInjector EXIF Editor is a professional, browser-based tool for modifying any metadata field inside image files. Whether you need to fix a wrong timestamp, add copyright information, embed GPS coordinates, or enrich IPTC fields for SEO — the editor provides a clean, intuitive interface that handles the technical complexity for you.

All editing happens locally in your browser. Your images are never transmitted to any server.

Key Features

Getting Started

1. Load an Image

Drag and drop, click to browse, or paste a URL. The editor accepts JPEG, PNG, TIFF, WEBP, and HEIC files.

2. Browse and Edit Fields

Metadata fields are organized into labeled sections. Click any field value to edit it inline. Empty fields appear with a placeholder prompt. Fields changed since loading are highlighted.

3. Validate Your Changes

The built-in validator flags issues:

4. Save the Modified File

Click “Save Changes” to download the modified image. The filename and all pixel data are preserved.

GPS Coordinate Picker

The built-in map picker eliminates the need to manually enter coordinates:

  1. Click the “Pick on Map” button next to the GPS fields
  2. Search for an address or location name
  3. Click the map to drop a pin at the exact location
  4. Coordinates are automatically populated in decimal degrees format
  5. Altitude can be fetched automatically from elevation data

Supported input formats:

Decimal degrees:  48.856614, 2.352222
DMS:              48°51'23.8"N 2°21'7.9"E
DM:               48°51.397'N 2°21.133'E

Batch Editing

Switch to Batch Mode to apply the same metadata changes across multiple images:

  1. Upload 2–500 images at once
  2. Define which fields to edit and their new values
  3. Choose conflict resolution:
    • Overwrite all — replace existing values
    • Fill empty only — skip fields that already have values
    • Merge keywords — add to existing keyword lists
  4. Preview changes on a sample image
  5. Apply to all and download as a ZIP

Batch editing use cases:

For the dedicated bulk tool, see: Bulk EXIF Editor

Lossless Editing Guarantee

ExifInjector’s editor uses a metadata-only write strategy:

  1. The original image pixel data block is extracted and preserved exactly as-is
  2. Only the APP1 (EXIF) and APP13 (IPTC) marker segments are rewritten
  3. The pixel data block is reattached without any recompression
  4. The output file’s image quality is bit-for-bit identical to the input

This means you can edit metadata as many times as you like with zero cumulative quality loss.
