Your file is not the product.
Supported browser workflows process inputs in the tab. Analytics receives an allowlisted tool or file-family label, never the file name or contents.

Local file router
Stop guessing which tool fits.
The router checks file type, a bounded signature or supported JSON structure, and the exact bytes. It recommends a destination; the destination tool still validates the input before producing a result.

Browse by the outcome
A small shelf of tools that do real work.
Search does not expose an inflated legacy catalog. It searches workflows with an explicit input, output and limitation; early-access tools are labeled separately.
All supported tools are shown.
Early access
Useful, directly accessible workflows still earning broader publication. They remain free and carry the same local-processing boundary, but are not presented as fully promoted products.
What makes the output useful
Finish now. Recheck later.
FastTool is designed around the handoff after the click: an artifact a person can use, the exact bytes that produced it, and a visible limit on what was not proven.
A result must leave the page.
Reviewed tools export the job output plus machine-readable or human-readable evidence. Empty dashboards and fake initial results are rejected.
Trust can be recomputed.
Where supported, SHA-256 hashes identify inputs and artifact bytes. Receipt Verifier independently checks supplied receipt and artifact pairs in the browser.
Clear limits
Before you choose a file.
Routing is intentionally narrower than conversion. It identifies a supported family and gives you a defensible next step; it does not silently upload, convert or certify the file.
Does the file router upload my file?
No. The browser reads the selected bytes locally to calculate SHA-256 and inspect a bounded signature or supported structured-file shape. File names, bytes and hashes are not sent in analytics events.
Is a routing match a PASS verdict?
No. It means FastTool found a relevant workflow. The destination tool must parse and validate the input again. Unsupported, encrypted, scanned, malformed or oversized inputs can still produce BLOCK or INDETERMINATE.
Why are some familiar utilities missing?
Older pages are not restored merely to increase URL count. A tool returns only after its engine, state handling, mobile experience, exports and claims pass the current quality gates.
How does FastTool make money?
The workbench and result path remain free and ad-free. Advertising can appear only on eligible guides or labs after consent and policy approval; sponsors or affiliate links cannot influence a tool verdict.
