EXIF Date Changer

Read the current EXIF date tags from a JPEG image and rewrite them to a new date — without re-encoding the image. Changes DateTimeOriginal, DateTime, and DateTimeDigitized fields in the EXIF APP1 segment. Runs in your browser; your image is never uploaded.

How to use this tool

  1. Upload a JPEG image. The tool reads and displays the current EXIF date fields.
  2. Pick a new date/time and click "Apply & Download".
  3. The modified JPEG (pixel data unchanged, only EXIF bytes patched) downloads instantly.

Technical note

EXIF date strings in JPEG are stored as 20-byte ASCII strings in the format YYYY:MM:DD HH:MM:SS. This tool locates each date string in the EXIF APP1 segment and overwrites it in place — the image bytes are not decoded or re-encoded, so there is zero quality loss. Works only with JPEG files (not PNG, WebP).

Why it's private

All processing uses the File API and ArrayBuffer in your browser. Your image is never sent to a server.
