About
Local Toolworks is a personal side project: fourteen small, focused utility tools built to handle everyday tasks without sending your data anywhere.
The tools
- Document Hygiene — inspect and scrub metadata from images and PDFs.
- Media Optimizer — resize images for platform limits.
- Time Coordinator — find shared meeting windows across time zones.
- Payload Workbench — format, convert, and encode payloads.
- RAG Cleaner — convert text or HTML into deterministic Markdown and JSONL chunks.
- Text Hygiene — inspect invisible Unicode and review writing-quality patterns without uploading text.
- Subtitle Converter — convert SRT to VTT and VTT to SRT subtitles without uploading them.
- Volumetric Weight Calculator — compute dimensional and chargeable shipping weight locally, with carrier factors and CBM for sea freight.
- Passphrase Generator — generate strong, memorable random passphrases locally from the EFF word list.
Why browser-local
Every tool processes your files and text entirely in your browser: no uploads, no accounts, no cloud storage, and no content telemetry. The data stays on your device unless you choose to download a result. This is the one promise that holds across all fourteen tools — see the Privacy Policy.
Status
Local Toolworks is publicly available and displays no advertising. Consent-based Google Analytics measures general site usage only after a visitor accepts it. The Cookie settings control allows rejection and withdrawal, while tool files and text always stay in the browser.
How the tools are verified
Each tool is checked locally before any change is accepted: unit tests,
TypeScript type checks, production builds, and browser smoke and
accessibility checks, all recorded under docs/evidence/ in the repository.
