Who this tool is for
For photo organization, delivery checks, privacy review, and copyright labeling. Understand a field before changing it, especially orientation, dates, GPS, and vendor data.
Real use cases
Correcting capture time
Fix a wrong camera clock, time-zone shift, or scanned-photo date while keeping the required EXIF date format.
Reviewing location before publication
GPS IFD may contain coordinates. Also inspect thumbnails and the destination platform for separate location data.
Adding author information
Artist and Copyright are standard fields, although platforms may strip or ignore them.
Steps
Read a JPEG, review each IFD, Tag, type, and value, then modify, remove, or add rows before exporting a new file.
Fields and export
Typical fields cover date, device, orientation, GPS, and copyright. Export rebuilds EXIF while retaining JPEG image data.
What to check after download
- The new file opens with correct orientation and color.
- Read the exported file again and verify critical field types and values.
- Check once after uploading because platforms often re-encode and strip metadata.
Common reasons a job fails
- No entries are found
- The file may have no EXIF, use an unsupported layout, or have been stripped by another platform.
- MakerNote cannot be preserved
- Vendor data uses internal offsets and cannot be safely rewritten in every case.
- A date or number cannot export
- The field type and value format do not match. Check ASCII, integer, rational, and Tag requirements.
