Inspect File Properties and Metadata
Read complete, accurate metadata from documents, images, audio and video — dates, camera settings, document properties, hashes and file-signature validation.
What is File Info?
Inspect a file before uploading it when a portal reports the wrong format, excessive size, or unsuitable photo dimensions. A filename extension alone does not prove what is inside the file: renaming .png to .jpg does not convert an image.
Compare the detected type, size, and available image dimensions with the portal’s requirements. Photo metadata can also contain location or device details. Some files contain little metadata, and a timestamp can reflect copying or downloading rather than when the document was created.
When should you use File Info?
- You received a photo and want to know when and with what camera it was taken
- You need to confirm the exact pixel dimensions of an image before using it in a design or print job
- You want to check the real format and size of a file before uploading it somewhere with limits
- You are troubleshooting a PDF and need to see which software produced it and when
- You suspect a file has the wrong extension and want to verify its actual format
- You are reviewing an image before sharing it and want to see what EXIF data it carries
- You need the creation or modification date of a document for records or a dispute
- You are organizing a batch of files and want quick technical details on each one
Benefits of using File Info
Completely free, no account
File Info is 100% free forever with no sign-up, login, email, or payment ever required. Open the page and inspect a file right away.
Your file is deleted automatically
The file is processed on a secure server and deleted automatically right after processing. Nothing is stored, logged, or shared.
Deep technical detail
See format, size, image dimensions, EXIF, creation date, and other properties that your operating system's basic file info leaves out.
Works across file types
One tool reads PDFs, images, and documents, so you do not need a separate viewer or utility for each kind of file.
Nothing to install
Everything runs in your browser on Windows, macOS, Linux, Android, and iOS. There is no software to download and no watermark added to anything.
Fast and readable
Metadata is presented in a clear, organized layout instead of raw code, so you can find the detail you need at a glance.
How to use File Info
- 1
Open the File Info tool
Go to the File Info page in any modern browser on your desktop, tablet, or phone. There is nothing to install and no account to create.
- 2
Upload your file
Select or drag in the PDF, image, or document you want to inspect. The file is sent to a secure server for processing.
- 3
Let it read the metadata
The tool analyzes the file and extracts its format, size, dimensions, EXIF, dates, and other technical properties.
- 4
Review the details
Read the organized breakdown of your file's metadata on screen. Everything is shown in plain language rather than raw data.
- 5
Inspect the next file
When you are done, your uploaded file is deleted automatically. Upload another file if you need to check more.
Common problems & how to fix them
Upload it to File Info and check the reported format. The detected format reflects the file's actual contents, not just the name.
Some files simply carry no EXIF, often because it was stripped when the image was edited, screenshotted, or shared through an app that removes it. In that case there is nothing more to display.
Encrypted or password-protected files can limit what metadata is readable. Remove the password or use an unprotected copy, then inspect it again.
This usually points to a large file or a weak connection. Wait for it to finish, or retry on a more stable network.
Not every file stores an original creation timestamp. The tool can only show the dates that are actually recorded inside the file.
That is expected. File Info reads metadata embedded inside the file, while your OS often shows filesystem details that can change when a file is copied or moved.
Before you use the output
- Compare the detected format with the portal’s accepted formats.
- Check file size and, for images, width and height separately.
- Treat missing metadata as missing information, rather than proof that a file is safe or authentic.
