File type inspector

How to use File type inspector

1. Provide the source

   Choose the supported original file using the file picker or drop zone. Check the accepted input types listed above the workspace. Read the operation note before starting, because supported syntax and file limits are part of the result contract. The original file is not overwritten or renamed by this workflow.

2. Choose the intended result

   This operation uses a fixed report format, so no extra output configuration is required. Change settings according to the file or text you actually supplied. Defaults are a starting point rather than a promise that every source uses the same conventions. Recognizes common images, PDFs, ZIP-based Office/EPUB files, archives, audio and video containers. Unknown binary data is reported as unknown rather than guessed from its extension.

3. Create and inspect the output

   Use the main action button to run file type inspector. Local processing checks the source and reports malformed or unsupported inputs. A completed job appears in Your results, with a download action and a preview when the output supports it. If the operation fails, read its message and correct the source or settings before retrying; changing only a filename does not change file contents.

4. Save and verify the result

   Download the finished output and open it in the application or workflow that will consume it. Choose the original source, adjust the settings, create the result and inspect the saved output. Check the values, layout, encoding or parsed structure relevant to your task. Keep the source when you may need another set of settings later. Temporary job downloads are session-owned and expire; saving your own copy is the way to retain a result.

Understand the settings

This operation uses fixed output settings. Choose and order the supported files as described above, then review the output notes.

Try file type inspector with a small source

Choose one small supported * file. Use the initial settings, inspect the result and then change one setting to understand its effect. Recognizes common images, PDFs, ZIP-based Office/EPUB files, archives, audio and video containers. Unknown binary data is reported as unknown rather than guessed from its extension.

Check your result

Choose the original source, adjust the settings, create the result and inspect the saved output. Recognizes common images, PDFs, ZIP-based Office/EPUB files, archives, audio and video containers. Unknown binary data is reported as unknown rather than guessed from its extension. Open the saved output in the app or workflow where you plan to use it. Check one representative result before repeating the same settings with more files. The original files stay unchanged.

What to know before you start

• Files are processed on this device. Browser memory and engine-specific limits apply. Save results before reloading.
• Recognizes common images, PDFs, ZIP-based Office/EPUB files, archives, audio and video containers. Unknown binary data is reported as unknown rather than guessed from its extension.
• Upload one file with a combined size of at most 100 MB. The completed output must fit within 200 MB.
• Files are checked by the local engine; a matching filename alone is not proof of valid contents.
• Selections and completed jobs stay available while you navigate inside this tab. Use My files to revisit results. Reloading or closing the tab clears the workspace; download results you want to keep first.
