JPEG Metadata Reader

About JPEG Metadata Reader

Every photo from a phone or digital camera carries invisible metadata alongside its visible pixels — camera make and model, the exact date and time taken, exposure settings, and sometimes precise GPS coordinates. This data is normally hidden from view but easy to check directly.

This tool reads a JPEG or PNG file's embedded metadata by parsing the file's binary structure directly — for JPEGs, it locates and decodes the EXIF segment (a TIFF-format data block embedded in the file); for PNGs, it reads the image header chunk for basic dimension information, since PNG doesn't carry EXIF-style metadata the same way JPEG does.

The parser implementation was verified against real JPEG files with known embedded EXIF tags (written using Python's Pillow imaging library as an independent reference), confirming every extracted field — camera make, model, orientation, resolution, and timestamp — matched exactly.

This is useful for checking what metadata a photo carries before sharing it publicly, verifying a camera's settings used for a specific shot, confirming when and with what device a photo was taken, and general curiosity about the hidden data embedded in image files.

How it works

1. Upload a JPEG or PNG file. Read entirely in your browser.
2. Metadata is extracted automatically. File type, dimensions, and any embedded EXIF fields.
3. Review the results. Camera details, timestamp, resolution, and more, clearly labeled.
