メタデータとは、基本的に他のデータに関する情報です。
多くのファイルには、最初に目にする見た目の内容以外に、追加または隠れたデータが含まれています。電子書籍、写真、動画、音楽、ドキュメントなどには、すぐには見えないデータが含まれている場合があります。
Metadata comes in a handful of kinds, and most files carry several of them at once.
オンラインでファイルの EXIF を確認できるということは、他の人も同じことができるという意味です。ファイルに含まれるすべての情報を把握することは、プライバシーの観点から非常に重要です。インターネット上で共有する写真やドキュメントに、世界中に公開したくない情報が含まれていないか確認しましょう。
A metadata viewer, a metadata reader and a metadata checker all mean the same thing: something that opens the hidden layer and shows it to you. This one reads the file in full detail rather than a summary, lists every field it finds, and lets you save the result as a PDF report.
メタデータを表示Every medium writes its metadata in its own format. Photos use EXIF for the camera settings and XMP for titles, captions and rights. Audio files use ID3 tags for the artist, the album and the encoder. Video keeps its fields in the container alongside the streams, and PDF and Office files keep document properties such as the author, the company and the dates.
You do not have to know which standard your file uses. Upload it and the viewer reads whichever ones are there, then lists the fields under their own names.
Metadata2Go.com はオンラインの EXIF データビューアです
写真には、画像に関する有用な情報を含む EXIF データが保存されています。シャッタースピードや焦点距離などの情報が画像内に記録されています。また、位置情報を見ることで、写真が撮影された場所を知ることもできます。
写真と同様に、動画にも撮影場所に関するメタデータが含まれます。さらに、AVI や MP4 のようなコンテナ形式には、コーデックや動画・音声ストリームなどに関するメタデータも含まれています。
ドキュメントにもメタデータが含まれる場合があります。ファイルサイズや作成日時といった情報に加え、ドキュメントの作成者や作成に使用したソフトウェアに関する情報も含まれます。
Music and voice recordings carry ID3 tags: the artist, the album, the track number, the year and the software that encoded them. Podcast files often keep a description and a chapter list in the same place.
An ebook keeps its own record of the title, the author, the publisher and the language, plus the reading software that last opened it. Upload the file and the viewer lists the fields it holds.
The metadata viewer has no format list. It accepts any file type and reads whatever the format stores, so an archive, a font or a design file can be checked the same way a photo is.
Open the metadata viewer and upload your file. Photos, documents, video, audio and ebooks are all accepted.
Press Start. The viewer reads the file and pulls out every metadata field it can find.
Go through the fields under their own names: camera, location, author, encoder, dates and the rest.
Save the metadata report as a PDF if you want to keep it or pass it on.
The files people check for metadata are personal by definition. Here is exactly what happens to yours.
Every upload and download runs over an encrypted connection, so your files cannot be read on the way. The download link is random and cannot be guessed.
The whole pipeline is automated. Nobody reads, looks into, or copies your files, and they are never used to train AI models.
Files are processed on servers located exclusively in Europe, under a signed data processing agreement. You keep the copyright and the ownership of every file.
Metadata is information about other data. A file keeps a record of itself: the camera that took a photo, the software that made a document, the length and codec of a video, the artist behind a track. None of it appears when you open the file, and all of it travels with the file wherever you send it.
Upload the file to the metadata viewer and press Start. The viewer reads the file, lists every field it finds under its own name, and lets you save the whole report as a PDF. Nothing is installed and no account is needed.
Any of them. The metadata viewer declares no format list, so photos, PDFs, Word and Excel documents, MP4 video, MP3 audio and ebooks are all accepted. What each format stores is different, so the viewer lists the fields the file you upload actually carries.
Yes. Reading metadata is free and needs no account, and a file can be up to 75 MB. A free account and the paid plans raise that limit.
EXIF is the metadata standard cameras and phones use for photos. It records the camera and lens, the shutter speed, the aperture, the ISO, the date the picture was taken and often the GPS coordinates. EXIF is one kind of metadata among several: documents, video and audio use standards of their own.
Often, yes. Phones and many cameras write GPS coordinates into the EXIF block of a picture, and those coordinates point at a real address. Upload the photo to the metadata viewer to see whether yours carries location data before you share it.
Use the app that strips hidden fields: upload the photo, press Start, and download the cleaned copy. The viewer shows you what a file carries, and that app takes it off without changing the picture itself.
Uploads and downloads run over an encrypted connection, and files are processed on servers located exclusively in Europe under a signed data processing agreement. The pipeline is automated, so nobody reads or copies your files, they are never used to train AI models, the download link cannot be guessed, and you keep the copyright at all times.
Pick an app, upload a file, and read what it says about itself. No account, no install.
