Optimize Image

Edit Image Metadata

Write EXIF fields — author, copyright, description, orientation — into a JPG without re-encoding it.

Choose a file to convert. It's processed locally — never uploaded. Tip: add several files to convert them all at once.

{ } How to use

  1. Choose a JPG.
  2. Fill in the fields you want to set — anything left blank is not written.
  3. Select Process and download. Check the result with Image Info & EXIF Viewer.

{ } How it works

Edit Image Metadata works on the file you upload. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Inputs

  • JPG image — upload a file (.jpg,.jpeg,image/jpeg); it is read locally in your browser
  • Artist / author — a value
  • Copyright — a value
  • Description — a value
  • Software — a value
  • Date and time (YYYY:MM:DD HH:MM:SS) — a value
  • Camera make — a value
  • Camera model — a value
  • Orientation — choose one — Leave unset, Normal, Rotate 90° clockwise, Rotate 180°, Rotate 90° anticlockwise (default: Leave unset)

Output

A downloadable JPG file — use the Download button in the Output panel.

{ } Common uses

  • Stamp your name and a copyright line onto photographs before publishing them.
  • Add a description that photo software and screen readers can pick up.
  • Fix a photo that displays sideways by correcting its orientation flag.

{ } Limitations

  • JPG only. PNG and WebP store metadata differently, and there is no EXIF segment to write.
  • Existing EXIF is replaced rather than merged. A partial edit that left half of the old camera’s fields behind would look deliberate and be wrong.
  • The fields listed are the ones worth editing by hand. GPS coordinates, lens data and maker notes are read-only here.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

Yes — add several files and they’re all processed and downloaded together as a ZIP.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Does this re-compress my photo?

No, and that is the point. Only the metadata segment is rewritten; the compressed image data is copied across byte for byte. A tool that decoded and re-encoded the picture would lose a little quality every time you corrected a typo in a copyright line.

Why was my accented character changed?

EXIF text fields are 7-bit ASCII. Characters outside that are replaced with a question mark rather than written as bytes other software would misread. Keep names plain, or put the full text in a caption elsewhere.

Will this make my photo private?

No — the opposite. This writes metadata. To strip it, including GPS, use Remove Image Metadata.
