Runs on your device. Your files are never stored.
Short answer
To find out what type a file is, add it to FileFleet: it reads the file’s first bytes, which say what it really is, and compares that with its name. If the extension is wrong or missing, you can download it with the right one. Nothing is uploaded.

Questions
Do my files get uploaded?
No. FileFleet runs entirely in your browser, so your files never leave your device. Close the tab and they're gone.
Is it really free?
Yes. No account, no daily limits and no watermark on your files.
Why would a file have the wrong extension?
Downloads, email attachments and phone transfers sometimes lose or change it, so a photo arrives as “file” or a PDF as “.bin”. The contents are fine; only the name is wrong.
