About File Tools

Workforge File Tools are file-level utilities: identify a file by its actual bytes, recover files with wrong extensions, inspect metadata, and hash for integrity checks. Everything runs in your browser. Your files are never uploaded, never scanned by a third party, and never retained anywhere.

The first tool live is File Identifier & Recovery. Drop in a batch of files and the tool reads their magic bytes, tells you what each file actually is (JPEG, PNG, MP4, HEIC, PDF, ZIP, and more), and offers to rename them with the correct extension. This is the fastest way to recover photos and videos that were renamed to something wrong (commonly .dll from ransomware or broken sync tools) as long as the file itself is intact.

Coming soon: a hash generator (MD5/SHA-1/SHA-256), an EXIF viewer that reads camera metadata in-browser, a header repair tool for lightly corrupted images, a duplicate-file detector, and a batch renamer. If you have a file-level utility that would save you real time, let us know.

Frequently asked questions

Are File Tools free?

Yes. Every Workforge tool is free, browser-only, no signup, no watermark, and no server-side processing. Your files never leave your device.

How does File Identifier work if you cannot see my files?

The identification runs entirely in your browser. When you drop files in, JavaScript reads the first few kilobytes of each file, compares those bytes against a table of known file-format signatures, and reports what type it actually is. Nothing is sent to any server.

Can this recover ransomware-encrypted files?

No. If a file has been encrypted, the raw bytes are scrambled and no rename will restore it. The tool detects likely encryption and warns you rather than pretending a rename fixes anything. Check nomoreransom.org for known decryptors and consult a professional.

What formats does File Identifier support?

Images (JPEG, PNG, GIF, WebP, HEIC, BMP, TIFF), video (MP4, MOV, MKV/WebM, AVI, M4V), audio (MP3, WAV, FLAC, OGG), documents (PDF), and archives (ZIP, 7z, RAR, GZIP). The full signature list is documented in the package README.

Will this rename a real DLL or EXE?

No. Real Windows executables are detected by the MZ header and blocked from rename. The tool always tells you what the file actually is before offering to change anything.
