Help and troubleshooting
Find answers about file formats, common issues, privacy behavior, and the best way to check a result before you trust it.
If a file does not behave the way you expected, start here before assuming the tool or the file is broken.

Supported file types
Images and PDFs are the strongest fit today. Video, audio, ebooks, and some office-style documents still give useful results, but some fields may be missing.
How file handling works
When a format works well in the browser, FileMetaHub keeps the work on your device. If a tool cannot do the full job, it should say so clearly.
Large or unreadable files
If a file is damaged, locked, or difficult to read, FileMetaHub should show a clear note instead of pretending everything worked.
Verify the result
After removal or editing, open the exported file again in View Metadata or a comparison tool to confirm the result.
When a result looks incomplete
Sometimes a file result might look like it's missing fields, but the file itself is still perfectly valid. This usually happens when a format doesn't share all its details with the browser, or if the metadata was removed before you got the file.
Check the 'File Details' first, then browse the metadata and sensitive tabs. If you're looking for a specific field that isn't there, you can try comparing it with another version of the file or using one of our more specialized tools.
The easiest way to verify a cleanup
The best way to check your work is to open the new file in 'View Metadata' right after you download it. This gives you a fresh look at exactly what's inside the new version instead of relying on the old results.
For extra certainty, try a side-by-side comparison. It's the fastest way to confirm that sensitive fields like GPS coordinates, author names, or software tags were actually removed or changed the way you wanted.
What happens in your browser
We've built FileMetaHub to keep your files on your device whenever possible. Most common checks and edits happen directly in your browser, so your file content isn't sent to a separate server for processing.
If you move a file between tools on this site, we might keep a temporary local copy in your browser's memory so you don't have to upload it twice. This local handoff is automatic and expires quickly.
Common issues
Is FileMetaHub free to use?
Yes. The public tools are free to use. You do not need an account to open them.
Does FileMetaHub upload or store my files?
For the formats that work well here, the tool does the job in your browser. If a file needs a lighter result or a different step, the page should say that clearly.
What is file metadata?
File metadata is the extra information stored with a file. It can include details like file type, size, author, software, timestamps, camera information, or GPS coordinates.
Which file types work best on FileMetaHub?
Images and PDFs are the best fit right now. Video, audio, ebooks, and some document formats can still be checked, but the amount of detail depends on the file.
How do I remove location data from a photo?
Open Photo GPS Checker or Metadata Remover, confirm that the image contains location data, create a cleaned copy, then open the new file again to make sure the GPS fields are gone.
How can I check whether metadata was removed?
Open the cleaned file again in View Metadata or compare it with the original. That is the easiest way to confirm that the fields you cared about are no longer there.
Can I compare two files online?
Yes. FileMetaHub includes comparison tools for images, videos, and PDFs so you can review file details and metadata side by side.
What is the difference between a MIME type and a file signature?
A MIME type is the format label reported for a file. A file signature is the byte pattern at the start of the file. Looking at both gives you a better idea of what the file really is.
Why does my file show limited or partial metadata?
Some file types do not expose every field in the browser. When that happens, FileMetaHub should show what it found and what it could not read instead of guessing.
Why is the cleaned image a different file size?
Removing metadata creates a new copy of the image. That can change compression, file size, or both.
How can I check that metadata was really removed?
Open the cleaned file again in View Metadata or compare it with the original file. That is the easiest way to confirm that the fields you cared about are gone.
Why does a file open in one tool but not another?
Each tool is focused on a different job. A file may be readable for basic inspection but not for editing, cleanup, or deep parsing.
