JEITA established Exif version 2.2 (a.k.a. Version 2.1 of the specification is dated 12 June 1998. The text extractor will allow you to extract text from.The Japan Electronic Industries Development Association (JEIDA) produced the initial definition of Exif. Among the file types supported are those used by Canon (CRW, CR2, CR3), Fujifilm (RAF), Hasselblad (3FR, FFF), Leica (RAW, RWL, DNG), Nikon (NEF, NRW), Olympus (ORF), Panasonic (RAW, RW2), Pentax (PEF, PTX), Samsung (SRW), Sigma (X3F), and Sony (ARW, SRF, SR2).Upload your files and change their file type from your browser, and then download. The EXIF reader is based on Phil Harvey's Exiftool utility, which can analyze not only jpg and png images, but also a broad range of RAW file formats.
Likewise, you can find out where the photo was taken by looking at the location information An online exif data reader can show you all these hidden information.The metadata tags defined in the Exif standard cover a broad spectrum:Developed in 1995 by JEIDA for JPEG images, EXIF data was later added to TIFF. Information such as shutter speed and focal length are stored inside an image. Exif is supported by almost all camera manufacturers.Metadata From Photos Photos contain exif data that can give you useful information about the picture. The latest version 2.3 was released on 26 April 2010, and revised to 2.31 on July 2013 and revised to 2.32 on , was jointly formulated by JEITA and CIPA. Version 2.21 (with Adobe RGB support) is dated 11 July 2003, but was released in September 2003 following the release of DCF 2.0.
( August 2020)The Exif tag structure is borrowed from TIFF files. You can help by adding to it. A thumbnail for previewing the picture on the camera's LCD screen, in file managers, or in photo manipulation software.This section needs expansion with: changes. This includes static information such as the camera model and make, and information that varies with each image such as orientation (rotation), aperture, shutter speed, focal length, metering mode, and ISO speed information. Digital cameras will record the current date and time and save this in the metadata. Date and time information.
When Exif is employed in TIFF files (also when used as "an embedded TIFF file" mentioned earlier), the TIFF Private Tag 0x8769 defines a sub-Image File Directory (IFD) that holds the Exif specified TIFF Tags. When Exif is employed for JPEG files, the Exif data are stored in one of JPEG's defined utility Application Segments, the APP1 (segment marker 0xFFE1), which in effect holds an entire TIFF file within. The Metadata Working Group has guidelines on mapping tags between these standards. For descriptive metadata, there is an overlap between Exif, IPTC Information Interchange Model and XMP info, which also can be embedded in a JPEG file.
Some cameras can be paired with cellphones to provide the geolocation. Recorded GPS data can also be added to any digital photograph on a computer, either by correlating the time stamps of the photographs with a GPS record from a hand-held GPS receiver or manually by using a map or mapping software. Some other cameras have a separate GPS receiver that fits into the flash connector or hot shoe. As of 2014 , many cameras and mobile phones have a built-in GPS receiver that stores the location information in the Exif header when a picture is taken. When these formats are used as Exif/DCF files together with the DCF specification (for better interoperability among devices of different types), their scope shall cover devices, recording media, and application software that handle them.The Exif format has standard tags for location information.
For this reason most image editors damage or remove the Exif metadata to some extent upon saving. The derivation of Exif from the TIFF file structure using offset pointers in the files means that data can be spread anywhere within a file, which means that software is likely to corrupt any pointers or corresponding data that it doesn't decode/encode. Many image gallery programs also recognise Exif data and optionally display it alongside the images.Software libraries, such as libexif for C and Adobe XMP Toolkit or Exiv2 for C++, Metadata Extractor for Java, PIL/Pillow for Python, LEADTOOLS or ExifTool for Perl, parse Exif data from files and read/write Exif tag values.The Exif format has a number of drawbacks, mostly relating to its use of legacy file structures. While many recent image manipulation programs recognize and preserve Exif data when writing to a modified image, this is not the case for most older programs. Photo-sharing communities like Panoramio, locr or Flickr equally allow their users to upload geocoded pictures or to add geolocation information online.Exif data are embedded within the image file itself.

Although the FlashPix extensions allow information to span multiple JPEG APP2 segments, these extensions are not commonly used. Exif metadata are restricted in size to 64 kB in JPEG images because according to the specification this information must be contained within a single JPEG APP1 segment. For example, someone might blank out a licence registration plate of a car (for privacy concerns), only to have the thumbnail not so updated, meaning the information is still visible.
There is no way to record time-zone information along with the time, thus rendering the stored time ambiguous. (In 2009, CIPA released the Multi Picture Object specification which addresses this deficiency and provides a standard way to store large previews in JPEG images. These non-standard extensions are commonly lost if a user re-saves the image using image editor software, possibly rendering the image incompatible with the original camera that created it.
Some software records this information using the GPSImgDirection tag along with custom GPSPitch and GPSRoll tags. It could also establish relative camera positions or orientations in a sequence of photos. Such data could help to establish the relationship between the image sensor's XYZ coordinate system and the gravity vector (i.e., which way is down in this image). There is no standard field to record readouts of a camera's accelerometers or inertial navigation system. Related tags are: "OffsetTime", "OffsetTimeOriginal" and "OffsetTimeDigitized".
For example, a whistleblower, journalist or political dissident relying on the protection of anonymity to allow them to report malfeasance by a corporate entity, criminal, or government may therefore find their safety compromised by this default data collection.In December 2012, anti-virus businessman John McAfee was arrested in Guatemala while fleeing from alleged persecution in neighboring Belize. Many users may be unaware that their photos are tagged by default in this manner, or that specialist software may be required to remove the Exif tag before publishing. For example, a photo taken with a GPS-enabled camera can reveal the exact location and time it was taken, and the unique ID number of the device - this is all done by default - often without the user's knowledge. Since the Exif tag contains metadata about the photo, it can pose a privacy problem. These tags were inherited from the TIFF 6.0 standard and are required even though for images produced by digital cameras, image resolution values such as ppi are meaningless. (The length unit itself is specified by the tag ResolutionUnit.) By default, these tags in combination are set to 72 pixels per inch (ppi).
McAfee later claimed to have edited the EXIF data from his phone to provide a false location. The photo's metadata included GPS coordinates locating McAfee in Guatemala, and he was captured two days later.
