What this tool does
Local File Workbench is a private browser-side triage desk for messy file batches. Upload PDFs, images, SVGs, ZIP archives, Office documents, fonts, text files, and unknown binaries, then get one Markdown report that summarizes detected file types, browser MIME hints, extension mismatches, duplicate candidates, PDF metadata, image privacy metadata, risky archive paths, Office macros or embedded objects, font structure, and recommended Toolora tools for the next specialist pass. It is designed for vendor attachments, content handoff folders, CMS upload batches, legal or finance document intake, support tickets, and any workflow where you need a fast first look before opening, extracting, forwarding, or publishing files. The workbench does not upload, execute, extract, or modify files.

How Local File Workbench fits into your work
Use it before upload, handoff, archive, support review, or any moment where a file needs one local check before it leaves your machine.
File jobs
- Checking file type, size, metadata, and obvious mismatch signals before sharing.
- Preparing mixed folders for upload, archive, intake, or review.
- Keeping sensitive files in the browser instead of sending them to an account-based service.
File checks
- Do not treat the extension alone as proof of the real file type.
- Review metadata before a file goes to customers, vendors, or a public page.
- Keep the original file until the copied, converted, or exported result is verified.
Good next steps

- 1 File MIME Type Inspector Upload files and inspect filename, size, browser MIME type, extension, and magic-byte signature locally. Open
- 2 ZIP Manifest Inspector Read a ZIP central directory locally and flag traversal paths, encryption, duplicate names, and risky ratios. Open
- 3 Office Document Inspector Inspect DOCX, XLSX, and PPTX package structure for macros, media, embedded objects, custom XML, and size hotspots. Open
Real-world use cases
Triage vendor attachments
Review archive paths, Office package signals, image privacy metadata, and extension mismatches before a team opens shared files.
Prepare CMS upload batches
Spot duplicates, oversized images, SVG script risks, and file type mismatches before content goes into a publishing queue.
Build handoff evidence
Export one Markdown report with recommended next tools and keep it beside hashes or approval notes.
Common pitfalls
Treating a filename extension as proof of file type.
Forwarding images publicly before checking GPS, EXIF, or XMP metadata.
Extracting unknown archives before reviewing paths and uncompressed sizes.
Privacy
Files are processed locally. The exported Markdown can reveal filenames, metadata fields, and internal archive paths, so share the report carefully.
