Как определить формат файла онлайн
Do you have a file that has no extension or an incorrect extension?
Select your file and we will detect the file type automatically
Our online file type detector to determines the true file type based on the file contents, not the extension. For example, just because your file is named «file.doc» it doesn’t necessarily mean it’s a Word document. It could be any type of file that just has an incorrect extension.
The extension of a file can be misleading since its simply part of the name of the file. If you take an «.gif» file and rename it to «.doc» your operating system can be confused on which application should open the document.
DetectFileType allows you to upload a file and analyze the bits and bytes of it to tell you what is the true filetype of your document.
We can provide additional details about some documents such as details for image files such as jpeg and png. For example, a png file can give results like «PNG image data, 262 x 296, 8-bit/color RGBA, non-interlaced». This gives the type fo the file, the pixel sizes, color bits, and whether it is interlaced.
In additon to the file type and suggested extensions we also give the MIME Type as a convenience to those who need it for their programs.

Have you ever found a file on your computer without an extension or has an incorrect extension? CheckFiletype.com helps you determine the true file type of any file based on the content of the file, not the extension. Simply use our online tool to upload the file and we will test it and show you the results.
CheckFileType does not require an e-mail or registration. The purpose of this site is to provide a quick tool to help you determine the file extension for an unrecognized or unknown filetype.
What is a file type? Every file has a particular format. Files are either binary or ascii. Common ascii files would be simple text or more complicated formatted text such as PDF or XML. Common binary files are images (jpeg, gif, png) or compressed files. But the file formats can be layered, such as DOCX or PPTX. These are a collection of ascii XML files in a zip archive which makes it a binary file.
In some cases such as zip files this tool may search the contents of the archive to give you the file type of each file contained in the archive.
About your privacy We store your file temporarily for processing, and after one hour it is removed permanently from our server. Your file transfer is secure using up to date encryption methods.
Detect a File Type
This online application inspects a file signature and classifies it according its content. The file description, its size and MIME type will be shown. All files processed by your computer/device. More than one hundred file types supported. If several files selected, only the first one is processed.

FileTypeDetector
Detects file type by filename or content and generates correct mimetype.
FileTypeDetector
Files type detector based on file name extension or file content (binary content).
- Usage
- Installation
- Supported formats
Usage
File Type detection
- Detection by file name: Detector::detectByFilename(. filename. ): array|boolean
- Detection by file content or stream content: Detector::detectByContent(. filename/resource. ): array|boolean
Both functions will return an array with following elements in case of success:
- [0] — Type of file ( Detector::AUDIO and so on)
- [1] — Format of file ( Detector::MP3 and so on)
- [2] — Mime type of file ( ‘audio/mpeg’ for example)
In case of failure it will return false .
$type = wapmorgan\FileTypeDetector\Detector::detectByFilename($filename); // or $type = wapmorgan\FileTypeDetector\Detector::detectByContent('file-without-extension'); // or $type = wapmorgan\FileTypeDetector\Detector::detectByContent(fopen('http://somedomain/somepath', 'r')); Mimetype generation
To get correct mimetype for file only there is getMimeType($file) function.
$mime = wapmorgan\FileTypeDetector\Detector::getMimeType($file); // or $mime = wapmorgan\FileTypeDetector\Detector::getMimeType(fopen('somefile', 'r')); Installation
Install package via composer:
composer require wapmorgan/file-type-detector Supported formats
Available to use types and their formats.
