How to access the metadata of any file

Access the metadata

When you go shopping for a bag of potatoes or a box of cereal at the supermarket, taking a look at it you’ll see that it includes nutritional information and ingredients, as well as where it was made or who distributes it. The digital equivalent is metadata.

According to Wikipedia, metadata is data about data, information about data that is not visible to the naked eye but which, by means of labels, tells us many things about a file or document.

Metadata can be found in virtually any digital file: HTML documents, system files, photographs, videos, audios and songs, text documents, spreadsheets…

Metadata is very useful because it provides additional information to that which we obtain simply by opening a file or accessing a web page.

In addition, they serve for your organization, cataloguing or to improve the performance of applications or services.

A practical example. When you take a picture with your mobile phone, thanks to metadata we know what device was made with that image, what resolution and quality have, where it was made, when and other technical data.

Next we are going to see online tools that will help us to see the metadata of different files and documents to know what data can be extracted from our digital content if we decide to share it.

ExtractMetadata

With the short name ExtractMetadata or Metadata Viewer in Spanish, this handy online tool helps us unravel what metadata is hidden in a file or document we have on our computer or from a web link.

The advantage of ExtractMetadata is that it reads different formats of image, video, document or audio: HTML, PDF, PS, Microsoft Office (Word DOC, Excel XLS, Powerpoint PPT), StarOffice (SDW), OpenOffice (SXW), DVI, MAN, FLAC, MP3, OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), ZIP, ELF, S3M , XM , AVI, FLV, REAL, RIFF, MPEG, QT and ASF.

Get-Metadata

Another web tool for reading metadata is Get-Metadata, which supports various formats such as WEBM, WAV, GIF, 3GP, DOC, PNG, XLSX, MOV, MP3, PDF, SVG, MP4, ZIP, DOCX and JPG.

Drag the file to the main window and you’ll learn about it in documents, videos, and photos. Specifically, size and format, RAW and MIME data, creation and modification dates, resolution, etc.

Metapicz

If you are only interested in image metadata, Metapicz will show them to you.

The tool is very simple. Upload the image or indicate its online address and you will see the camera with which it was made, GPS location and XMP, EXIF and ICC data.

As a curiosity, Metapicz has an extension for WordPress.

EXIF Data Viewer

Also specialized in images and photographs, EXIF Data Viewer reads various file formats up to 20 MB.

Specifically, you can upload or provide the link of images JPG, TIFF, GIF, PNG, PSD, BMP, RAW, CR2, CRW, PICT, XMP and DNG.
