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.

01 · Local first

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.

02 · Useful artifacts

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.

03 · Exact verification

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.
